If you intend to use this material for a school paper, be aware that your teachers will have learned something entirely different from what is presented here. This chapter has no information on AD 2012.
The Mesoamerican / Maya calendar contains cycles within cycles, all of which are held as significant to some degree in determining the "quality" of any day in time. Many of the cyclical features look like remnants of earlier calendar systems which could not be discarded, but were carried forward in time as each change in the calendar was forced upon the users with a change in the structure of the Solar System. I would thus suggest that the current calendar -- because of its inclusion of these arcane, and in some cases near-useless, features -- shows faithful and careful adjustments to changes in the number of days in the year over a very long period. I'll suggest, in fact, that the calendar can certainly be traced back with certainty to the era starting in 3147 BC. I think this is clearly shown from the remnants retained at later times. In fact, a page of the Chilam Balam, which deals with the events of 2349 BC, specifically states, "And then days of the year were introduced." But this is the addition of a round of 13 numbers superimposed on the original "monthly" calendar of 20 named days.
- The original count of years was started in 8347 BC, when the southern plasmoids first showed up.
- In 3147 BC, as the 13th Baktun was completed, the "Era of the Gods" came to a close, and a new count was started of Baktuns, Katuns, Tuns, Uinals, and Days. A calendar of days was instituted, amounting to a rotation of 20 named days. These repeated 12 times to account for the 240 days of the year. The 12 may have rotated at the same time as the 20 named days.
- In 2349 BC this was augmented with a rotation of one extra day, a total of 13 numbered days (representing a half period of the Moon) simultaneously with the 20 named days. This is called the "Tzolkin," and consists of a total of 260 distinctly identified days (named and numbered) before repeating again, and exactly filling the year of 260 days.
- In 1492 BC another calendar was introduced, called the "Haab," consisting of 20 numbered days rotating through 18 named "months," which totalled 360 days.
- The Haab was adjusted in 747 BC to add 5 extra days (a short month), so that the calendar then totalled 365 days.
- An accurate count of days was also established in 747 BC, with a system called the "Long Count." The Long Count tallied days, "months" of 20 days, years (called "Tuns") of 360 days (not 365), double decades of 20 Tuns (called "Katuns"), and a measure of 400 years, called simply "400," or, in the nomenclature of archaeologists, "Baktuns."
It is also certain that there was a calendar, in the sense of a count of years from the retrocalculated year of 3114 BC, since the Maya Chilam Balam correctly places the earliest event of the current era in the properly named double-decade Katuns.
I should also note that the Baktuns and Katuns were probably in use already by 8300 BC, for the Chilam Balam has reference to this in Book 11 which details the "first creation" of 8347 BC. In 3114 BC (actually 3147 BC), with the collapse of the "Era of the Gods," the count of years had reached 13 Baktuns, and was reset to zero.
The date of 3147 BC, when the count of Baktuns of the calendar was reset to zero, was known as the "second creation." With the institution of the Long Count in 747 BC, the Olmecs were able to calculate backwards into the past to determine the exact names and numbers of the Tzolkin and Haab when zero was reached in 3147 BC (which calculated as 3114 BC) -- the Tzolkin day is 4-Ahau and the Haab day is 8-Cumku.
... preliminary observations
The Long Count, as interpreted by archaeologists, initially used August 11, 3114 BC, on the Gregorian calendar as a starting point. In that there is a two-day difference in calendars between early Olmec (and current Guatemala) and the calendar of the Maya (and Aztecs), the other widely accepted date is August 13, 3114 BC. In both cases it is assumed that the year has always been the same length as today -- 365.2422 days. The Classical era Maya (AD 400 to 700) also used this measure, arriving at the proper retrocalculated Tzolkin and Haab days at the beginning of the current creation, even though they are likely to be incorrect.
The archaeological count of days which starts at August 11, 3114 BC, was first derived by Joseph Goodman in 1905. Juan Hernández in 1926 came up with a calculation of August 12, which was followed in 1927 by John E. Thompson's calculation of August 13. In 1935 Thompson revised his calculation to August 11. As the dean of Maya archaeologists, Thompson's estimate is generally used today, although any number of researchers think that the date of August 13, 3114 BC, is more likely to be correct."Overwhelming support for the precise placement of the Thompson [August 11] correlation number came in the 40's and 50's, when newly discovered calendar counts still being followed among the Quiche, Kekchi and Ixil of Guatemala all supported the [August 11 date]."
-- John Major Jenkins [http://edj.net/mc2012/fourahau2.htm]
The above "correlation dates" are on the Gregorian calendar, converted from a measure known as the "count of Julian days" used by astronomers since the 16th century AD. The actual "astronomical year" for 3114 BC is -3113, based on recognizing a "year zero." The Gregorian calendar will match solar years under the assumption that the length of the year has not changed.
The Julian calendar, in use from about 40 BC to about AD 1500, and not to be confused with "Julian days," is based on a year of 365.25 days, and thus the Julian year is slightly longer than the Gregorian year. By 3114 BC the Julian calendar places dates about 13 months further into the past than the Gregorian calendar. On the Julian calendar the zero date is September 4, 3115 BC.
There have been suggestions that the Maya made a two-day correction at some time in the past, and that this accounts for the difference of two days between the Long Count notation found on monuments in antiquity, and in the continued use of the earlier Tzolkin among contemporary tribes.
In fact, Vincent H. Malmstrom, writing in Cycles of the Sun, Mysteries of the Moon (1997), suggests that this happened in circa 48 BC -- that the Maya in effect skipped two days, thus setting the calendar ahead by two days. Malmstrom sets out when and where this would have happened, and the reasoning behind the change, but admits that his "story" is pure conjecture.
But a "correction" carries with it the suggestion of an absolute and uniform use of the Tzolkin and Haab calendars by many tribes spread over a large area since remote antiquity. The concept of uniform agreement doesn't work among humans. I think it should be considered that by 747 BC, when the Long Count was devised, there were already some diverse regional opinions on the concept of where one era ended and another started -- a question about the existence ("completion") of two days which had not been seen in progress. Considering that the 2000-year-old Tzolkin was in use among many diverse tribes, it is likely that some stubborn local opinions prevailed.
The "August 11" calendar reaches further into the past by two days. It correctly fits the start of the Long Count on February 28, 747 BC, and accounts for later retrocalculations of some past events by the Olmecs. But it was supplanted by the "August 13" calendar because the "August 13" calendar "correctly" fit what was thought to be the quality of a number of important dates in the year 685 BC, and in 1492 BC. (See the discussion in the chapter "The Day of Kan.")
My sense is that in the Valley of Mexico, and perhaps also in the Olmec coastal region, the "August 11" calendar was replaced by the "August 13" calendar by 400 BC, but long after the use of the "August 11" calendar had been exported and adapted by tribes in Southern Mexico and Guatemala, where it has been retained to today. (Some researchers have suggested that the calendars may have started in Guatemala. This likely is an erroneous opinion.)
It should also be pointed out that August 11, 3114 BC (or August 13), is not the start of the current era, but is the end (the completion) of the previous era. The texts at Palenque, for example, make this clear when it is read:"And then the past epoch ended. On 4-Ahau 8-Cumku [presumed to be August 13, 3114 BC], 13 Baktuns were completed."
The transliterated text reads:"(And then) there was an event / (on) 4-Ahau / 8-Cumku / were completed / 13 Baktuns"
There can be little doubt, no matter how it is translated, that this phrasing speaks to the completion of a previous 13 Baktuns -- 5200 solar years. It points directly to an earlier calendar which would have started in 8347 BC. Occasional stelae specify the placement on the day 4-Ahau 8-Cumku of "the three stones" or alternately the first "image of the turtle." The references here are to a day in the year 8347 BC, but the day name and number are known only because of a retrocalculation by the Olmecs or the people of the Valley of Mexico in antiquity, probably after 600 BC, which found this day name and number for the restart of the calendar in 3147 BC.
Support for a correlation based on the date of August 13 comes from the record of eclipses, which cannot be off by a day. But my observation is that the starting date of February 28th, 747 BC, Gregorian, corresponding to the Long Count date of 18.104.22.168.0, can only be upheld with an "August 11" correlation. This matches the start of the Era of Nabonassar in the Eastern Mediterranean region (the evening of February 27, 747 BC) and the start of the Roman calendar (the day after February 28th). I think the arguments among archaeologists and historians may be meaningless. It should be recognized that there were two Long Counts in use, and that they differed by two days. [note 1]
The first Tzolkin date inscription was in use at the Zapotec site of San José Mogote in the Oaxaca region in about 600 BC. By 400 BC the Tzolkin and Haab calendars were in use at Monte Alban in Oaxaca.
Since 1939 the earliest Olmec Long Count discovered was depicted on Stela C from Tres Zapotes as 32 BC (Julian). Malmstrom notes that this stele would celebrate a total eclipse of the Sun as it rises out of the Eastern Gulf of Mexico, if the August 13 Thompson correlation is used. Otherwise it would be off by two days. Malmstrom notes a transcription error in the stele (carving three bars rather than two to accompany the three dots for the "kin") and then writes about the eclipse:"... whose path ... passed right over the Olmec ceremonial center of Tres Zapotes at dawn on the morning of August 31, 32 B.C. A more frightening celestial event can scarcely be imagined, for the sun rose out of the Gulf of Mexico totally black except for a ring of light around its outer edges. [It was] described as an annular, or ringlike, eclipse, and subsequent calculations at the U.S. Naval Observatory have revealed that the disk of the sun was 93 percent obscured (personal communication). Surely, a 'day without a sunrise' is not likely to have gone unrecorded by the Olmecs!"
He concludes with:"... therefore, the inscription of Stele C, erroneous though it seems to be, appears to confirm the accuracy of the original Thompson correlation value [August 13] between the Olmec calendar and our own."
Malmstrom also identifies a much later eclipse seen at Copan (Copán) on June 29, AD 763 (22.214.171.124.17 6-Caban 10-Mol), and suggests that it had been predicted. Again, the date agrees with a lunar eclipse only if the "August 13" correlation is used. The date was recorded on a half dozen stelae. Archaeologists have not as yet accepted this. (Surprise!)
It should be obvious also from many inscribed stelae that it is the completion of a time period that is celebrated, not the start. The event of 3114 BC is known as the "second creation," which is inferred from the fact that the event which we know as the "flood of Noah" is consistently called the "third creation." The reason the "second creation" of 3114 BC ended with the completion of 13 Baktuns (the count of years then went to zero Baktuns), is that the predecessors of the Olmecs had already been counting years (solar years) for a span of 13 Baktuns since 8347 BC.
In that the Sumerians managed to have a count of years (in days) from 4200 BC, it is reasonable to suggest that the Olmecs or their predecessors were also perfectly capable of this. "Counting," after all, must have been one of the high sciences even for the only slightly more remote Cro-Magnons.
The Beginning of Time[Image: August 13, 3114 BC, day "zero" of the Maya calendar. This reads, "13 Baktun, 0 Katun, 0 Tun, 0 Uinal, 0 Kin, 4-Ahau 8-Cumku, was (first) seen the image."]
The phrase of "the image," some stelae complete as "the image of the turtle." This would represent the first appearance of the southern plasmoid. We can thus place the first showing of Peratt's southern plasmoid in 8347 BC. This is reasonable also, for 8347 BC is about 1500 years after Earth emerged from the shadow period of the Younger Dryas and enough time to reach the outer edge of the lower plasma expulsion of Saturn (the edge of the cup form).
It has always been strange to note that the "zero" number for the Baktun at the start of the current era (3114 BC) actually has a value of 13 Baktuns. This fact is mostly passed over on the assumption that "13" has some magical or ornamental value among the Maya, who are the people who had reference to the date of 126.96.36.199.0.
The date of the "first creation" is not the nova event of Saturn in 4200 BC, which the Popol Vuh describes as the "dawning of the light," but an event 4000 years earlier.
In the iconography of the Maya, the "turtle," which appeared in 8347 BC, at the time of the "first creation," is often combined with the appearance of Jupiter ("Hun-Nal-Ye") as the "First Father" in 2349 BC, the time of the "third creation." Just like the second and third southern plasmoids would seem to have appeared out of the carapace of the "First Turtle" sometime after 8300 BC, so First Father is shown to rise out of a turtle carapace, assisted by Hunahpu and Xbalanque (from the era of the 7th century BC). This scene is repeatedly shown on bowls and vases.
In Maya Cosmos Freidel and Schele present the imagery of a painted pot showing six Gods in council with a seventh and elder God. The council is advising the seventh god to "bring into existence" and "put in order" the place called "black is its center" -- a fit description of the deep shadow at the center of the Absu which changed size and shape over the year.
The elder God (God L) is easily identified as Jupiter as well as First Father. The six Gods have various names, of which some are easily identified. God "Three Born Together" is obviously the three plasmoids of the south and God "Nine Footsteps" is Mars. Subtracting God "Three Born Together" of the south leaves five Gods all associated with the polar configuration of the north. This is the same number as listed in the Popol Vuh (see the chapter "The Popol Vuh" for details). These are Uranus, Neptune, Saturn, Mercury, and Mars, all of which were easily distinguished in the earliest time after 9500 BC, although some disappeared behind (or above) each other by 5800 BC, and Mercury is misnamed for Venus, which probably did not exist as early as this council is meant to depict. God L (Jupiter) is here distinguished from the polar configuration planets, and it is a rare insight to suggest that indeed at the time of the council, sometime before 4200 BC, Jupiter had been known and seen for eons, and therefore was properly represented as very old.
This illustrated pot also points up the Mesoamerican concept of the simultaneity of time. The council of the six Gods happens after the "first creation" of 8347 BC as far as the narrative of the Popol Vuh is concerned, resulting eventually in the creation of the Sun -- the lighting up of Saturn. But the disposition of the dark spot in the Absu, in fact, the whole of the Absu, is not tackled until the "third creation" of 2349 BC. Most of the six Gods had long since disappeared from view by then. Archaeologists today think that the "dark spot" is a dark area of the cloud of stars of the Milky Way galaxy.
The other (and more common) image which is often represented as first appearing on 4-Ahau 8-Cumku, is the setting of the three hearthstones in the sky. These have been identified by Schele as a star of the belt of Orion and two of his feet (Alnitac, Rigel, and Saiph). The cluster M-42 is enclosed in this triangle, like a fire at the center of a three-stone hearth. The constellation is below (slightly east) of the intersection of the equatorial and ecliptic, and removed from the brightness of the Milky Way. In fact, these stars first showed up in 2349 BC, the date of the "third creation," at a location known as "Lying-down-Sky" which must represent the gap in the Absu during either of the equinoxes. Other names for the shadow gap in the Absu are the "Earth Partition," and "Black is the Center" (as in the text of the pot, above). Even though the shadow fell on the Absu, no stars would have been seen in the dark area.
Thus the three hearthstones could not refer to the second creation of 3147 BC. Additionally, if we hold that the skies have been invariant, then at no time in the past could these three stones have been placed, for they were always there. This suggested to me that the "setting of the three stones" probably referred back to the "first creation" when three stones (the three southern plasmoids) were set beneath the mighty stone (Saturn) of the north, as the Chilam Balam relates in Book 11.
The date of 3147 BC is actually a reasonable estimate for the start of the current era, that is, as the date for the close of the "Era of the Gods" and the end of the first 13 cycles of 400 years. The Olmecs must have had a record of the number of solar years which had lapsed since various worldwide cataclysms -- or were able to place events in named year tallies, at least since 3147 BC, and very likely since 8347 BC (although no record of time spans shows up among the sparse Mesoamerican records of past history). Time spans between "ages" (after 3147 BC) show up in later Mesoamerican legendary histories and are correct or nearly correct, and match the records of other civilizations. The records of the Chilam Balam books of the colonial-period Maya are accurate to the Katun (20-Tun period) after 3147 BC (after allowing for some slight-of-hand by the 16th-century-AD scribes).
When the Long Count was established in 747 BC by the Olmecs, they added six Baktuns (counts of 400 Tun years) to a base date of 0.0.0.0, based on the assumption that the year (the Tun) had always consisted of 360 days. This was correct in this instance, because the year had indeed consisted of 360 days since the establishment of earliest Olmec ceremonial center after 1500 BC (San Lorenzo). Thus the Olmecs also removed from the Long Count calculation the five-day correction that was added to the annual Haab calendar in 747 BC -- the "years" in the Long Count are based entirely on the earlier 360-day intervals, not on 365-day intervals. The rather arbitrary addition of 2400 Tuns (six Baktuns of 400-Tun years) to the Long Count would bring the actual "zero" date to 3147 BC, off from the 3114 BC year by 34 years. [note 2]
A "Tun" is a year. Before 3147 BC (the thousand years of the "Era of the Gods" and the 4000 years before that) the Tun was 225 days (I have assumed). After 3147 BC (the worldwide flood) the Tun was 240 days. After 2349 BC (the "flood of Noah") the Tun was 260 days. After 2193 BC (the fall of Akkad and the Old Kingdom) the Tun was 273 days. After 1492 (the Exodus and the fall of the Middle Kingdom) the Tun was 360 days -- and at this value it remained in its Long Count use, even though 5 additional days were added to the year after 747 BC when the year changed to the current value. Although the earlier "years" were shorter, the effect of adding 2400 Tuns (6 Baktun) was to have a calendar which reflected solar years, and is thus nearly identical to the accepted (scientific) chronology -- where it is assumed that all years in the past were Gregorian years of 365.2422 days.
When researchers calculate backwards to 3114 BC, using an actual count of days, they use a 365.2422-day Gregorian year. The researchers and archaeologists thus end up being able to place events in certain "years" which will match the intent of the Olmec and Maya Long Counts. Both are in error in terms of the actual number of days before 747 BC, but both are nearly correct in terms of "years" if thought of as representing solar years. Both are in error because the later Maya also ignored the fact that the Olmecs knew the length of the year had been 360 days prior to 747 BC, and, in fact, designed the Long Count to count 360-day Tuns, not 365-day Haab years.
I have no problem with the suggestion that history might have been remembered from long before 3114 BC (or 3147 BC), or that some aspects of the Mesoamerican calendar date back to 2349 BC, and the year count dates from 8347 BC. After all, in Northern Mesopotamia people had been accounting for trade products since 8000 BC, and kept track of days since 4200 BC. [note 3]
Mesoamerican iconography seems to spring to life sometime around 1500 to 1200 BC without any sign of a developmental phase. These are the dates of the first images carved in stone or engraved on celts. This suggests that the stone carvings were preceded by a long period of works in wood and other fugitive (perishable) materials, a period possibly lasting thousands of years. As an example of how long such records could last, note that the Dresden Codex, a book on plaster-coated tree bark, was transcribed in about AD 1200 from material dating to before AD 700. It was sent to Spain after AD 1550. Such long endurance of books suggests the possibility of other records dating from more remote antiquity -- including, of course, chronological records.
Over the following few paragraphs I will speculate about possible early calendars, although after 2349 BC the use of a calendar is certain. In circa 2350 BC Yao, the first "emperor" of China corrects the calendar. In the Enuma Elish, dating from Babylon sometime after 2000 BC, but detailing events in circa 2350 BC, the God Marduk does the same. Both of these instances assume there was an earlier calendar. The Hyksos imposed a new calendar in Egypt after 1500 BC, and similarly Moses receives a new calendar from God at about the same time. In both of these last cases the new calendars point to the replacement of a calendar in use before 1500 BC. The following is the speculation about early calendars for the Olmecs.
The First Calendar
Before 3147 BC the year was 225 days long. A very simple but sophisticated calendar system could have been in use: the year was divided into 9 groups of 25. Fingers of one hand could be used to count up to 4. When 5 was reached the other hand closes a finger -- representing 5. Thus the other hand could hold a total of 25 units. The "Nine Lords of the Night" rotated nine times through the sets of 25 to count to a total of 225 days.
I am using the five fingers because both Olmec and Mayan ciphers were represented in base 5. The "Nine Lords of the Night" were still being counted 4500 years later, and still rotated endlessly through nine names. [note 4]
The "Nine Lords of the Night" together with the 25 "day numbers" (or more likely "day names") would produce 225 unique names for the days of the year. This sort of system would constitute a calendar which might have been a model for the later Tzolkin, which rotated 13 numbers against 20 names.
Who the "Nine Lords of the Night" were, or what they represented at the time before 3147 BC, is unknown. I suspect, on the basis of other sources, that the "Nine Lords of the Night" represented Jupiter and the eight close satellites, visible at close range after 3147 BC. Jupiter was known as "The Nine." See the chapter "The Chilam Balam" for this.
The "Nine Lords" might also represent an assignment of nine gods to the nine rings of the Absu -- the House of Nine Bushes. These would show at night.
left hand: 1 through 4
right hand: 5 through 25
9 Lords of the night (9 x 25 = 225 days)
An Intermediate Calendar
Of course, the previous is speculation. But for the period after 3147 BC, we can be much more certain of a calendar. After 3147 BC the year was (I suspect) 240 days long. The 240 days could be counted as multiples of 20 and could be made to fit 240 if 12 sets of 20 were to be used. A lunar calendar might be suggested for this era, with the period of the Moon at 20 days, but there was as yet no Moon. There is not a single suggestion of lunar calendars anywhere in the world before 2350 BC. It is more likely that the 20-day periods represented agricultural periods. It is possible that the 20 "day names" were rotated against 12 "day numbers" -- which would give 240 unique date-names to the year. [note 5]
The Mayan word for the 20 days is "uinal" which translates as "moon" and means "month." It also means "person," since a count of 20 day names could be understood as addressing all a person's fingers and toes. This person became "personified" as a "time-lord" who brought in the month as a parcel. Because of some such metaphorical construction, the continuity of time for Mesoamerican people was never a certainty (as it is for us) -- the bearer of time might not arrive with his burden.
The "Nine Lords of the Night" -- whatever their value might be -- remained in use.
A Person: 20 digits and toes (day names)

9 Lords of the Night
The Tzolkin Calendar
After 2349 BC the year went to 260 days. At this point speculation stops, although I have reached a year length of 260 days by somewhat of a circular argument (in the Appendix "Chronology Notes"). A line of a page of the Books of the Chilam Balam, dealing with the events of 2349 BC, reads:"And then days of the year were introduced."
There certainly was a calendar in use, dating back some 3700 years, as the Books of the Chilam Balam show. This calendar consisted of a rotation through twenty named days. Only the preexistence of the twenty named days makes sense in the subsequent introduction of the Tzolkin calendar.
The count of days, the 260-day calendar known as the Tzolkin, as instituted in 2349 BC, was a lunar calendar. The Moon was intercepted in or after 2349 BC (see the chapter "The Day of the Dead"), and was probably in a stable orbit within a few years. Mesoamerica started to rotate 13 new "day numbers" against the existing 20 "day names" to yield 260 uniquely named days constituting a year. Brilliant! Every day of the year was individually identified.
It is unlikely that the period of the Moon was 20 days at this time, or that there were 13 months to the year. More likely the number 13 is a count of a half moon period -- from a new moon to a full moon, and back. Thus the period of the Moon was 26 days (perhaps initially) and there were 10 lunar months of 26 days in the year -- 20 half months.
Typical of Mesoamerican thinking, it was the completion of a change to a full moon or the finish of the waning to a new moon that counted -- 13 days for each. Thousands of years later, the Maya still call the 20-day period a "month," a "moon," and a "person" -- but not the 13-day period. This actually seems strange if the Moon's period was 26 days. Anyway, each of the twenty days of this "moon period" had a separate name -- Imix, Ik, Akbal, Kan, etc. The glyphs for the day-names are unique from other glyphs in that all twenty are graphically represented as figures of some sort within the frame of an escutcheon seated on three feet. Some of the glyphs have not been recognized, which probably speaks to their extreme antiquity, as does the whole of the arcane nature of this calendar system. Glyphs which are known include tropical plants and animals as the environment of the location where these names were first selected.
[Image: 20 Day Names of the Tzolkin Calendar.]
This system of a day count which rotates endlessly through 260 number-name combinations is actually the best evidence that an earlier calendar had existed. If the Lords of the Night were kept in use since 3147 BC, then there was probably a similar pressure to retain the day names after they became obsolete because they had constituted the base of a previous calendar.
Today the Tzolkin (which is still in use) shows no concern with time as a linear progression, only as a repeating cycle. This is endemic to the Mesoamerican languages, which understand time in topological terms, rather than a series. An "historical awareness" in terms of understanding time as a linear progression does not take hold for another 2000 years. Mayan words for time involve references to round things, circles, and cycles. The future is expressed as going from here to there, as if invoking geography. We do this also, mentally, but our geography of time is a single line with no bounds.
The Tzolkin calendar makes no sense to us, who are used to a completely different method of tallying days. But it fits in with the suggested earlier calendar which rotated the "Nine Lords of the Night" against day names. The strangest aspect of the Tzolkin is that the 13 numbers are rotated against the 20 names, rather than "numbering" each of the names in a sequence of 1 to 13. Perhaps stranger still is that the 20 are known as a "month."
The languages of Mesoamerican people did not use tense (serial time) in verbs, but only the sense of "on-going" and "completed." In this manner the cycling of 1-Imix, 2-Ik, and 3-Akbal makes some sense, because to count 1-Imix, 1-Ik, and 1-Akbal would leave the moon-period uncompleted until the 13th count was reached. Similarly 1-Imix, 2-Imix, etc., seems to repeat the Imix day pointlessly. The point was to reach 13, when the Moon would have become full, or new, and simultaneously keep up a rotation through the twenty day names. The result, at any rate, was to have a calendar with 260 separate names for each day of the year.

The question also occurs, why was this 260-day calendar kept in use when the length of the year and the period of the Moon changed one hundred and fifty years later in 2193 BC, and again in 1492 BC, and in 747 BC? There could be a number of reasons, but primary is the fact that the Tzolkin calendar, and the later Haab calendar, do not function as we would imagine a calendar to function, that is, as a sequence of numbers which have a one-to-one correspondence to the sequence of days, and are discarded just as the days are irretrievable once they have moved into the past. The Tzolkin has a different function to a people whose language base does not include a strong sense of time (as a "path"), but who do have a heightened sense of space and geography. In Mesoamerica, time had a spatial quality, and the Tzolkin functioned as a map to the domain of time.
I also think that the Tzolkin was kept for the same reason that the I Ching in China (dating from the Shang era) was never abandoned, even surviving the book burning of 213 BC. If the Maya or Olmec were at all like other people throughout the world, they would believe that all their fortunes and failures in life were predetermined. The only glimpse into the future was to "read" the qualities of each day, for like fate, each was different from any other (and Tzolkin/Haab day-name combinations do not repeat for 52 years). Using the Tzolkin as a guide to life was not unlike contemporaneous Mesopotamian and Indian astrology or the Chinese use of the I Ching. Even if the number of days in the year changed and a more rational calendar were to be adopted, the Tzolkin would have to remain in use without interruption.
Modification of the Tzolkin
After 2193 BC the year went to 270, 275, or 280 days. The Tzolkin could easily accommodate the 280-day year by adding an additional rotation of 20 days. I suspect, however, that the year changed to 273 days. By chance, the Tzolkin could also accommodate a year of 273 days, since it would only slip behind by a count of 13 days every year. [note 6]
That the calendar fell out of sync with the Solar year did not matter as long as the Tzolkin's primary purpose (after 150 years of use) was to determine the quality of the days of the year. Consider also that the rotation through the twenty day-names had been in use for 900 years. Certainly it was also kept because it represented high science to the Olmecs. It must have been in this period that an acumen in the analytical use of the Tzolkin was first developed.
We should also be aware that the science of the Tzolkin was used in the control of the Gods and spiritual powers. Specifically it was eventually used to control the travels of the Sun. This theme resounds through all of the history of Mesoamerica, and was repeatedly proven in the future to be correct and effective.
I suspect another cycle which has come down to us, a count of 819 days assigned in rotation to each of the cardinal points, was added in this era. Researchers have been unable to make anything of this cycle, except to note that 819 is the product of 7, 9, and 13. The period of 819 days revolved through the four cardinal directions.
Linda Schele and David Freidel, in A Forest of Kings (1990), note that in Maya texts the God K (also identified as God G-II), who clearly is Mars, is associated with the four directions. We therefore need to look to Mars.
The 819 days is also exactly three times the length of the year (273 days) at this time (3 * 273 = 819). It is possible that 819 days represents the synodic period of Mars when the Earth's year was 273 days, although unlikely. An orbital period of 720 days, derived by Patten and Windsor for the time period before 747 BC, is a much more sensible fit although it seems to have nothing to do with 819.
Donald W. Patten and Samuel R. Windsor, in The Mars-Earth Wars (1996), conclude that (for the purpose of their model, and as related to the period before 747 BC):"The model here proposes that Mars had an ancient 720-day orbit. Mars was in 1:2 resonance with the Earth, and it was in 6:1 resonance with Jupiter. Further, it was in a near 15:1 resonance with Saturn."
Both the orbital period and the synodic period would have been 720 days during this time; (720*360)/(720-360) = 720."Its orbital eccentricity was approximately 0.561; its perihelion was about 64,353,000 miles and its aphelion about 228,805,000 miles."
An eccentricity of 0.561 places the aphelion of the orbit of Mars in the asteroid belt, and the perihelion within the orbit of Earth, as I have suggested earlier. The eccentricity used by Patten and Windsor could have been found from their estimates of the calendar days Mars would have crossed over Earth's orbit.
A synodic period of 720 days actually makes a lot of sense, since we have no "mythical" indication that Mars was involved with worldwide disasters after the time of the visits of Horus of the Egyptians (3067 to circa 2750 BC) until the strikes in the 8th and 7th century BC. It could thus be suggested that the orbital period of Mars remained the same for all of the 2300-year time span since 3067 BC, when it first showed up near Earth, up to 747 BC (or 806 BC). [note 7]
In the previous era of 3147 BC to 2349 BC, the synodic period of Mars would have been (720 * 240) / (720 - 240) = 360 days. Thus Mars would show up in the same location of the sky every three years of 240 days, 2 * 360 - 3 * 240 = 0 (and once every year and a half). This three-fold repetition of the calendar year is, of course, also reflected in the mysterious 819 days, as noted.
Let me suggest, from this, the following: After 3067 BC, with the year at 240 days, the reappearances of Mars were marked, correctly, at 3 intervals of the 240-day year, 720 days. But this only lasted to about 2750 BC, going by the records of Egypt, when Mars no longer came close.
After 2349 BC, when the year went to 260 days, three of the 260-day Tzolkin were used instead, 780 days. This was incorrect, but that did not matter, for Mars had disappeared from consideration some 400 years earlier, and by the end of the previous era it was probably no longer recalled why Mars had been assigned to one of the cardinal directions at intervals of three calendar years.
After 2193 BC the year went to 273 days. As I have suggested earlier, the calendar was now accounted for with a 260-day Tzolkin cycle, plus one short 13-day Tzolkin cycle. Again, the assignment of Mars to the four cardinal directions was accomplished on a rotation of three "years" -- three 260-day Tzolkin periods plus three 13-day rotations, an 819-day year. This again was incorrect, but again did not matter. The interval of three years, tied to the four cardinal directions and the planet Mars, was a formal part of calendar computations, and had nothing to do with the close appearances of Mars before 2750 BC.
What then happened at 819-day intervals? Nothing much. Every two rotations through 819 days would advance Mars by about a quarter of its orbit; 819 - 720 = 99 days. This is about 1/8th of 720 days, and thus relocates Mars that much in the dome of the stars. Two rotations would move it by the distance of a cardinal direction. This may be the reason that the 819 days are associated with the cardinal directions. After 8 rotations through 819 days Mars is mostly back where it started from in the zodiac.
I am suggesting the association of 819 days with the cardinal directions, because it does not work for any other era. Apparently, once it was set in 2193 BC, the use of 819 days remained unchanged. The next opportunity would have been 700 years later, in 1492 BC. But no changes were made.
There is one additional iteration to consider, namely the rotation of the three-year cycle against the cardinal directions. When the year was 240 days, Mars would return to the same location in the sky at 1.5-year intervals. I was hoping that the 3-year cycle of cardinal directions would coincide with the actual location of Mars in the sky in a 15-year or 30-year interval. This would recognize the 30-year sed-festival interval of the Egyptians.
But it does not, as long as we associate the assignment of a cardinal direction with the starting date or ending date of a 720-day (three-year) period, as we normally would do. That would only account for a 12-year interval. If, however, we associate the cardinal directions each with the whole of a 720-day span of time, then it takes five rotations of three years to return again to the same cardinal direction, and thus 15 years -- even though this involves counting inclusively.
This is a rather inelegant solution from our perspective, as inclusive counting will produce incorrect intervals. This can be rescued, however, by having each following 15-year period start (and end) with the next cardinal direction in order. With this method there is no relationship between the cardinal directions assigned to the rotation through three-year periods and the fact that Mars shows up close to Earth at times, except the fact that Mars could be expected every other time a series of five three-year periods were completed, that is, at 30-year intervals. Arcane as this is, it is not unexpected of the Olmecs (who must have instituted this), in that they (and all of Mesoamerica) counted in fives.

The Haab Calendar
After 1492 BC the year changed to 360 days, and the period of the Moon changed to 30 days. This is certain from many sources throughout the world. A solution would have been to add five additional sets of 20 "name day" rotations ("months") to the Tzolkin, or to add five more numbers (from 13 to 18). But this would be completely unacceptable, for the Tzolkin had to remain as it was, as it had for at least 800 years. To extend the count would have been equivalent to changing our 7-day week to 9 days.
The only solution was to start up a separate calendar for the 360-day period. This was done by starting a rotation through the names of 18 "months" (Uinals) of 20 days each, called the "Haab" (augmented with 5 more days 700 years later). Now for the first time we see a calendar instituted which has a familiar sensibility, like the numbered days of our months. The 18 months were separately named, but only 20 days were assigned to each month. The glyphs for the months are completely different from the Tzolkin glyphs and have the characteristics of the later development of the written language. A number of them also simply translate to "first," "second," etc. But the "months" -- that is, the Uinals -- still were 20 days long as they were previously, and were called "months" -- that is, a word meaning "moon." [note 8]
[Image: The eighteen months of the Haab calendar plus the additional five-day period of the "sleep of the year," Uayeb.]
The 20 day numbers were most likely modeled after the 20 day names of the Tzolkin. The 360-day calendar of 18 months of 20 days also makes no sense, since the actual (lunar) months were 30 days long, but it neatly filled the year, and every three calendar months (60 days) coincided with two rotations of the Moon.
The Tzolkin remained in use, arcane as it was, to determine the quality of any day, and, nearly 3000 years later, as used by the Aztecs, determined the lot in life of a person named for a particular number-name day on which he was born.
The two calendars were entirely different, yet both were kept in use for the next 3000 years. (In some regions of Guatemala and Mexico they are still in use today.) Days were identified, in the Classical era of the Maya, for the number-name of the Tzolkin, followed by the number-name of the Haab. The two calendars of 260 days and 360 days would not repeat a combination of two names for 13 years.

The Haab Revised and the Long Count
After 747 BC the year changed to 365 and 1/4 days. The Olmec correction, like almost everywhere else in the world, was to add 5 unnamed days at the end of the year. For the Olmecs this was a 19th short "month" of five days, called "the sleep of the year." Actually this would shift the year one day backwards in the solar year every 4 years, for it did not account for the quarter day left over. The revised calendar in Peru actually added a leap day every four years. Mesoamerica through Classical times did not, with the exception of the Zapotecs at Monte Alban (after about 400 or 200 BC).
In 747 BC the Olmec also started to count days, perhaps to recalculate the length of the year after the Earth shock of 747 BC. This is known as the "Long Count" which was carried into the future without interruption for the next 2700 years, but was mainly used by the Maya until about AD 900. The count started on February 28 of 747 BC (actually the Julian year of -748) with all measures set to zero -- zero days (Kins), zero months of 20 days (Uinals), zero years of 360 days (Tuns), and zero "double-decades" of 20 Tun years (Katuns). In our notation of these Katuns, Tuns, Uinals, and Kins, the Long Count is rendered as 0.0.0.0. February 28, -748. This is the date of the start of the Babylonian "Era of Nabonassar" (which starts at nightfall of February 27th), and the same calendar day after which the Romans restarted the year since the 8th century BC. [note 9]
A larger unit, called a "Baktun," consisting of 20 "Katuns," (400 Tun years of 360 days) was added at the same time or at a later date. A starting "Baktun" value of "6" was assigned to February 28 of 747 BC. The official Long Count date for February 28 -748 (using our dotted notation) thus reads "188.8.131.52.0 11-Ahau 8-Uo," where "11-Ahau" and "8-Uo" are the day names in the rotating Tzolkin and Haab calendars. (This is based on the August 11 correlation of Thompson.) The odd day-names, both located in the middle of the Tzolkin and Haab calendars, confirm that the Tzolkin and Haab were already rotating simultaneously before this time.
It would be possible to estimate from this when the Haab was first instituted, or what the general plan for the Haab was. Others have suggested that it is likely that the summer or winter solstice was used to celebrate the start of the year. But this notion reflects our contemporary reductionist calendar concepts. Some people in Guatemala still celebrate New Year at the winter solstice, or actually at Christmas. I can only suggest, however, that the Haab had drifted more than 30 days over the 740 years of its use. But it is also possible that the Haab calendar and its later extra 5-day "month" were instituted without regard for an elegant design, and was arbitrarily added to the existing Tzolkin. [note 10]
What is of greater interest is to know how soon the Haab was corrected by adding 5 additional days. By the 18th month (of 20 days) after February 28, 747 BC, it would have been obvious that the year was now longer, and a 19th short month should be added. But since the Olmecs kept track of the setting position of the Sun by days of the Tzolkin and Haab, this would possibly have furnished a much earlier indication of how many days the year had slipped behind.
The intercalated 5 days were added probably as soon as the first one of the longer years was about to pass. The traditional use of the Haab in the Classical era adds the extra five days after the 18th month, Cumku. In fact it was added at the end of the first new longer year, as can be confirmed from the current usage by the Chiapas (see below). Otherwise there would not have been the amazing simultaneous coincidence with the start of the Era of Nabonassar.
Verification that the 5 days were added after only one of the old years had lapsed, comes from the practices of contemporary upland Maya in Chiapas, Mexico, who retain a form of the Haab calendar today. The contemporary Haab calendar, in this instance, starts directly after Christmas, that is, a few days after the winter solstice. No accounting is made of the fact that the calendar will slip backwards against the Gregorian calendar. Somehow an extra day is added every four years.
The year starts with a Haab month which, from its name, is the equivalent to the ninth month of the older Haab of antiquity, and continues in sync with the Haab of antiquity. The second month of the contemporary calendar is the 10th month of the old Haab, etc. There is one exception. The intercalated 5 days are placed after the third month (of 20 days), not after the last month. The third month of 20 days ends on February 24. The intercalated days start on February 25 and conclude on the day after February 28. [note 11]
The use of the Long Count, and especially the starting value of 6 Baktuns, shows that an historical awareness had developed by 747 BC. Six Baktuns represent 2400 solar years stretching back in time to 3147 BC. The Olmecs figured the past on the basis of 360-day years, but the actual length of the year does not enter the basic calculation of when the current era started. A Tun was a solar year; the length did not matter. By our methods of calculation, which assumes that the year has always been 365.2422 days, the 2400 "years" represent a starting date of 3114 BC.
The Long Count rotates through Tuns of 360 days (18 times 20), and all the future uses of the Long Count disregard the 365-day Tuns, and counted instead in 360-day Tuns. This is rather amazing, and probably confirms that the Long Count was started simply to measure the new number of days in the year.
Of course we use 365.24 days as the length of the year, and simply count backwards by days (called the Julian day count). Within a few hundred years after 747 BC, the Olmecs were doing the same thing, that is, using 365.24 days. The prior year length of 360 days used by the Long Count was ignored or forgotten.
That the Long Count was started in 747 BC is apparent from the fact that 184.108.40.206.0 of the Long Count falls on February 28, 747 BC, but also from the fact that this date completes a Katun 11. Katuns are named after the last Tzolkin day of a Katun; in this case the day 11-Ahau. This last is significant when we know from the 16th century AD Maya Chilam Balam that all of pre-history always was assigned to Katun 11-Ahau.
But 1400 years later, in circa AD 700, the Maya at the site of Palenque retrocalculate dates 3000 years earlier, and list them according to the notion that the past -- all of the past -- consisted of 365 day Haab years, not 360 day Haab years. The Maya (or their Olmec predecessors) also retrocalculated back to the very beginning of the current era (the "second creation") to find that the initial Haab and Tzolkin days name and numbers were 8-Cumku and 4-Ahau. This works for both the "August 11" and the "August 13" concordance.
What does not work in this retrocalculation, is finding a Katun 11 ending for the previous era. The previous era ends in 4-Ahau, and thus the Katun is named Katun 4-Ahau. Despite this, when the Chilam Balam (in Book 10) recounts events from before the start of the current era (before 3147 BC, but thought to be 3114 BC), they are listed as happening in Katun 11. The notion obviously is from the time in 747 BC, when the Long Count was instituted and a Katun 11 had just ended. See the chapter "The Chilam Balam Books."

Of course the rotating calendars make no sense. Only the Long Count made sense. One could tell how far in the past an event had happened, but only in terms of months (Uinals), which fell short of a cycle of the Moon, and years (Tuns) which fell 5 days short of the solar year. A relationship to the solar year could be kept by celebrating New Year at the summer (or winter) solstice, although solstice dates are not easy to determine. In fact, none of the people of the Central Valley of Mexico or the Maya of Mexico or the Guatemalan Peten celebrated or marked a solstice date, with the exception of the Chiapas mentioned above who remodeled their calendar to fit a Christian liturgical feast day.
The actual day-name and day-number of a New Year day would change with each year. In the Yucatan the Maya of the Classical era celebrated the new year on July 26, when the Sun passed directly overhead at the site of Edzna, as did the people of Teotihuacan in Central Mexico (circa AD 200). As best we can tell the Tzolkin and Haab continued to rotate without ever skipping a single day, although today the calendars maintained by some Guatemalan people are two days ahead of the count accepted by many archaeologists. There are, in fact, numerous instances even in antiquity that two calendars were in use, differing by two days. (See the chapter "Olmec Alignments" for instances.)
The simultaneous rotation through the 260-day cycle and the 365-day cycle would repeat every named day combination only once every 52 years (actually 52 "tun years"). That was of course significant in that it reflected the "traditional" possibility of reaching the end of creation (the so-called "52-year Venus cycle"), as was initially determined in the period between 2349 BC and 2193 BC. The 365-day year, without leap days added, also kept exact pace with the synodic period of Venus, which was probably much more important than any other considerations. As long as there was a strong interest in the movements of the planet Venus, it would make sense to not add the leap day, and retain the traditional calendars. The complex Tzolkin and Haab calendars spread everywhere in Mesoamerica, but the Long Count only saw wide use by the Maya.
The Katun Cycle
After circa AD 900 the Maya give up on the Long Count which had reached back 1500 years (4000 years if retrocalculated), and continue to use only a short cycle of Katuns -- 20 years of 360 days, about 19.7 solar years total for each Katun. Consecutive Katuns were collected in a repeating series of 13 Katuns (rather than the 20 Katuns constituting a Baktun), because the ending day-names of the Katuns repeat after 13 Katuns. Consecutive Katuns always are listed as starting with Katun 11, named after the last day, 11-Ahau, and are followed by Katun 9, etc., with the series of declining even numbered Katuns after the last of the odd-numbered Katuns, Katun 1.
The cycle of 13 Katuns is approximately 256 solar years. This series is all the Maya retain of their calendar, 600 years after the collapse of their kingdoms -- plus, of course, the endlessly repeating assignment of days to the Tzolkin, the Haab, and the "Nine Lords of the Night."
In the 16th century AD the Yucatan Maya insist that history starts with Katun 11-Ahau, where Katun 11 signifies the era of prehistory. Any list of events always starts with Katun 11-Ahau. This is seen in use in the 16th century AD Maya Book Of Chilam Balam Of Chumayel.
Others have suggested that this is because Katun 11-Ahau begins with 1-Imix, the first day of the Tzolkin. But in fact it is because a Katun 11-Ahau ends on February 28, 747 BC, when the Long Count (220.127.116.11.0) was instituted (using the "August 11" correlation, and actually the year -748). Katuns are named after the name of the last day of the Katun period, not after the day with which they start. It was always the ending of a time period, not the beginning, that mattered. For the Maya, unlike for us, a period of time did not exist until it was completed; it did not exist yet while it was still ongoing.
The Four Ages
The concept of "suns" or "sun ages" was recognized throughout Mesoamerica by various peoples, as well as by people in many other parts of the world. These are meant to represent various creations of the world, or recreations after a cataclysmic destruction. In Mesoamerica four ages were recognized by all except by the Toltecs and the Aztecs, who claimed that the world had been recreated five times. Both of these people held their own invasion of the Valley of Mexico as the last recreation of the world.
The creations and recreations can be pinpointed, but the series of dates runs into conflict with various concepts of what constitutes a new age.
The Olmec and Maya Long Count calendar starts the "current creation" in (the calculated year of) 3114 BC. This date does not count the two destructions of the Earth since that time, but only recognizes that conditions on Earth and in the skies were completely different before and after. This was known as the "second creation," and from this two ages are recognized.
Book 10 of the Maya Chilam Balam books places creations or recreations after floods, and thus recognizes three eras, the periods before and after 3114 BC, and the period after 2349 BC, this last started with an event known as the "third reign" or what would be the "third creation." But the dark skies after 1492 or 1440 BC are also dealt with as the start of a new creation. It is not surprising that this confusion exists, since Book 10 of the Chilam Balam is obviously derived from diverse sources.
The concept of "four ages" is a satisfying shorthand if we associate a change of the length of the year with each of the ages, and especially if these events can be associated with some worldwide catastrophe. But it does not work out that way. What can be gathered from the most reliable source, the Chilam Balam, is the following:
- There was a very earlier age, suggested in the Popol Vuh and detailed in Book 11 of the Chilam Balam -- the long period before Saturn went nova in 4200 BC and before humans were created. The "first creation" is in 8347 BC -- the first sighting of the southern ball plasmoid. Here we already have two periods, although the Sun was largely absent or occluded during the 1500 years of the Younger Dryas, which had ended a thousand years before 8347 BC.
- The "second creation" is 3147 BC. References to it are only implied in the text of the Chilam Balam from the fact that the "third creation" happened later, in 2349 BC. The second age is thus the era after 3147 BC (3114 BC as retrocalculated).
- The "third creation" is the event we know as the "flood of Noah." Book 10 of the Chilam Balam, however, places the "third creation" (incorrectly) in Katun 9-Ahau ending in 2266 BC, but should properly be placed in Katun 4-Ahau ending in 2345 BC.
The fall of the Absu, the "third creation," is noted as "the second baptism" with the implication that the first is the flood of 3147 BC (which is also mentioned). The reading of the Chilam Balam also implies the start of a new calendar. In this it parallels the Chinese Annals of Shu, as well as the Babylonian Enuma Elish, and, of course, the Bible's flood of Noah.
- Despite the fact that Jupiter flared up and lost its coma, disappearing from the skies in about 2150 BC, Jupiter remained the ruling God. Likewise the change in the Earth's orbit in 2193 BC was not an event which defined a new era. The "third creation" continued.
- The electrical contact by Venus in 1492 BC starts yet another age, the fourth. In fact the Chilam Balam notes that Venus "rubbed the Earth" in Katun 9-Ahau ending in 1486.2 BC (corrected), although this was likely the view of the Van Allen belts in glow mode. A new creation is also to be inferred from the mention of the establishment of the trees of the four cardinal directions. This is the third reference in the document to these trees, noted previously after 3147 BC and 2349 BC. There is also a reference to "walking in darkness," which can be identified as the 40 years or so after the contact by Venus in 1492 BC. The Israelites also "walked in darkness.""Then they perceived that the world was being created. Then creation dawned upon the world."
The reference to creation is suggested for 1492 BC by its placement in the texts, but could also refer to the 200-year climatic downturn experienced worldwide after 2193 BC.
- There are no further ages referenced. The year 747 BC, which occluded the Sun for two days and changed the orbit of the Earth, had no bearing on the list of ages. The Earth shock of 686 BC could have represented the start of yet another age, but the Chilam Balam specifically states that this was not to happen. Similarly, the nova event of 685 BC is mentioned but not counted as a new era. In actuality, the world was rescued by Jupiter.
I suspect that the Chilam Balam was transcribed from books indigenous to the Peten and Yucatan Maya. The story of these books may have differed from the records kept among the Olmecs of Veracruz and in the Valley of Mexico, which have not survived.
But we can count four ages from Olmec sources under a completely different paradigm: the site alignments used in the Olmec coastal area since 1440 BC, and in the Valley of Mexico since about 600 BC.
These horizon alignments for sunrise or sunset reference four dates. First, starting at San Lorenzo and followed by almost every later site, the date of April 19, 1492 BC is recalled in the alignment of the setting Sun to some mountain or volcano. Apparently when San Lorenzo was established, the horizon location of the setting Sun for that date was known.
Similarly, at La Venta the alignment for February 28, 747 BC was also known, since it was experienced. The date of August 12, 3114 BC, was calculated after 747 BC, with the aid of the newly developed Long Count. Various dates centering on July 685 BC, were also experienced and incorporated into the alignments of sites after 685 BC.
Last, in about AD 200, and at some locations, both since before and directly after 685 BC, the setting of the culmination of the Pleiades is used to signal the event of 2349 BC. These alignments show up at all later sites. The alignments are discussed in the chapter "Olmec Site Alignments."

The dotted notation, used by archaeologists as a shorthand to identify the Long Count, consists from left to right of measures known as Baktuns, Katuns, Tuns, Uinals, and Kins. These are nominally identified as:
- Baktuns are sets of 20 Katuns, or 400 Tun years, representing 400 years of 360 days (surprisingly, not 365 days). A Baktun represents about 256 years of our calendar. The word "Baktun" is an invention of archaeologists. The Maya simply called it "400" in representing 20 times 20. The count goes from 1 to 13.
- Katuns are double decades, representing 20 of the 360-day Tun years. The count goes from 1 to 20. This is about 19 years of our calendar.
- Tuns are "years" of 360 days. The count ranges from 1 to 20.
- Uinals are "months," where each count represents 20 of the day counts. Uinals range from 1 to 18. On reaching 18, the next higher number (the Tun) of the dotted notation is advanced one. 18 Uinals thus represent a Tun year of 360 days.
- Kins are days and count from 1 to 20. Actually, the range of 0 to 19 is used. On the 20th count, the next higher number (the Uinals) of the dotted notation advances one. Kins (days) thus count up to one Uinal "month" before advancing the next higher count.

For correcting Long Count dates which were retrocalculated by the Maya in circa AD 700 at Palenque, as well as the correction of the Katuns (where I have supplied the Baktun) of Book 10 of the Chilam Balam, a different correction should be used. This will be based on the suspicion that there did not exist a record in actual Long Count days for events before 747 BC, but only a listing by Katuns and Baktuns.
Here the correction is based on the fact that the Olmecs knew that the era prior to 747 BC represented years of 360 days, not 365.24 days. Thus our calculations, and those of the Maya, based on a 365.24-day year, would be off by 5.24 days per year before 747 BC, that is, the dates we use are placed too far into the past. The calculation is (3114-747) * 5.24 / 365.24 = 34 years.
So, for example, when in AD 700 the Maya at Palenque retrocalculated a date of 2360 BC for some event listed among the inscriptions at Palenque, it was based, like our calculations, on a 365.24 day year, and would be too far into the past by (2360-747) * 5.24 / 365.24 = 24 years. The date should be 2336 BC. But this is only partially correct because, going backward in time, the length of the year changed also in 1492 and 2193 BC.
The Maya were perfectly capable of calculating backwards, and making allowances for the extra 0.24 day of the year. Anthony Aveni, in Skywatchers of Ancient Mexico (1980), notes a number of instances among Maya inscriptions (at Copan) where successful attempts were made to indicate the length of the tropical year. The Maya ended up with a year of 365.2420 days, only 0.0002 days different from the current value of 365.2422 days.

See the chapter "The Chilam Balam Books" for a retelling of the creation of the world which dates back to thousands of years before 3114 BC (I would estimate 8347 BC) and which were apparently transcribed from Maya tree-bark codexes. Other pages of the Chilam Balam describe the darkness of the Younger Dryas (10,900 to 9,000 BC), and hint at ages dating to the equivalent of the European Magdalenian period (17,000 to 14,000 years ago) or earlier (I suspect to 41,000 years ago).

The Maya (and Olmecs) used a base-20 in their commerce, but it is difficult to maintain that they also did so with their calendar, as is often maintained. The "units" of the Long Count do not all advance as powers of 20, since the Uinals advance when reaching 18, not 20. Baktuns cycled at the number 13. The number 20 just happens to be a larger unit to count in, like our dozen or hundred. The glyphic representation is certainly in base-5.

Although some of what I have suggested is conjecture, I should note a remarkable similarity of the Mesoamerican 20 day names and 12 day numbers to the calendar of the Chinese Shang dynasty, after about 1400 BC, which rotated 10 "celestial day names" against 12 "earthly day names" to produce a similar calendar (of 60-day seasons), elements of which lasting well into the current era. The Chou dynasty extended the rotation of 60 day names to the names of years. This last persists today.
Although the Shang dynasty is much later than the period under discussion here (before 2349 BC), it would not be at all surprising if the Shang calendar represented a holdover from an earlier period, when the 240-day year was divided into four seasons of 60 days each, thus a total of 240 days. China experiences four distinct seasons; Mesoamerica experiences a completely different cycle of seasons. The Shang, at any rate, added the lunar month days to the 60-day periods to furnish nearly accurate calendar dates during the year.

I suggest a year of 273 days, based on conjectures developed in later endnotes of this text. Since 273 is 13 days more than 260 days, the Tzolkin could have been expanded by adding one round of 13 numbers, or the calendar could have been left to slip backwards 13 days per year. The reason for selecting the second might have depended on an initial attempt to keep the calendar in line with the half-moon periods of the previous era. This did not work out, for the Moon changed to a period of 27 or 28 days after 2193 BC, which we know from (later) Shang oracle records.

I have here neglected the intermediate return of Mars in 1936 BC, resulting in the destruction of Sodom and Gomorrah.
Patten and Windsor suggest a 108-year interval between possible double contacts of Mars and Earth, with the last in 701 BC, which I have as 747 BC. They suggest particularly close passes on 540-year intervals.
The interval of 540 years appears repeatedly in antiquity, and apparently was related to a "phoenix year" by Chairemon, a Coptic priest of the first century AD. It was not, as Patten and Windsor suggest, a measure of the Great Year of antiquity.

It is possible that the Haab was devised separately by a people different from those who devised the Tzolkin, and the two calendars were kept after a cultural merger after 1500 BC.

According to Ussher, the era of Nabonassar starts at midnight of February 26th, thus actually on the 27th. Ussher writes:"From twelve o'clock, on the first day of the Egyptian month Thoth, from Wednesday, February 26th, in the evening, in the year 747 BC, all astronomers unanimously start the calendar of Nabonassar."-- Bishop James Ussher, Annals of the World (1650)
Additionally, because of the Mesoamerican concepts that a day does not exist until it is completed, the Long Count use of "day zero" actually signifies the first day of the new era, so that the actual era-ending date is February 27th.

Note 10 --
The short five-day month can be neglected in any retrocalculation here, because it was instituted in 747 BC. If we take a hint from how the Olmecs dealt with other calendar adjustments, it would suggest that the Haab was instituted the day after the cataclysm of 1492 BC. From an earlier chapter we know that this happened on a Gregorian equivalent calendar date of April 19. (Bible tradition is April 17th.)
On February 28, 747 BC, the Haab day fell on 8-Uo. This is the 29th day of the Haab. Thus, in 747 BC, the annual secular calendar, which starts with 0-Pop, had started 29 days earlier in that year, equivalent to January 30 on a Gregorian calendar. Thus, between April 19, 1492 BC and February 28, 747 BC the Haab had slipped 80 days backward, which is four 20-day Uinal months. This number is not in any sense meaningful.
Alternately, taking into account the fact that before 685 BC the winter solstice fell some 15 days earlier, on December 8, so that the Haab would have restarted 53 days after the winter solstice. Except for the fact that 53 days represents a 52-day interval, this also is such an arbitrary figure, that it can only be suggested that there was no relationship between the Haab and either the winter or summer solstice.
Vincent H. Malmstrom, in Cycles of the Sun, Mysteries of the Moon (1997), dates the first use of the Haab to 1324 or 1321 BC, based on placing the day 0-Pop (the first day of the Haab) at the summer solstice. The calculation would only be in error by 8 years, since the extra five days have to be subtracted from the Haab for the period before 747 BC.
The usage of the Chiapas (see other endnote below) might bear out Malmstrom's conjecture that the New Year (the start of the Haab) was celebrated at the summer solstice, even though the Chiapas today start the year with the winter solstice (at Christmas), for they start with the ninth month (Uinal) of the traditional Haab calendar. The name of the month which starts the Haab is clear from the fact that the names of the first few months of the Haab translate to "first," "second," and "third." That would place the beginning of the Haab 160 days before Christmas (8 times 20). This is not at the summer solstice, but 24 days after (July 18).
When New Year is celebrated is a local option. The Maya, as with Teotihuacan, used July 26. In colonial times the Aztecs celebrated the start of the new year on February 26. (There are some discrepancies with respect to this particular date, however. See the endnotes to Appendix B, "Celestial Mechanics.")

See Gary H Gossen, "A Chamula solar calendar board from Chiapas, Mexico," in, Norman Hammond, editor, Mesoamerican Archaeology (1974). Although the Tzolkin was held as sacred, the Haab was apparently adjusted to start as convenient by various tribes.
