№ 21. Ancient Calendars and the Reconciliation of their Start and End Dates

PAGE STATUS: Concept page. Except for the sections on the Maya Long Count start and end dates, very little work has been done to develop these ideas. Please note that I discuss the Maya Long Count start and end dates on this page in order to reconcile them to the Yuga calendar and Aztec Sun Stone, but I refuse to refer to the Maya Long Count as a calendar.

The Yuga Calendar of India

The following paper by Christian Irigaray is the most authoritative work I can find on the start date of the ancient Yuga calendar of India. O downloaded the original PDF from www.academia.edu (awaiting permission)


In this paper, the author concludes

There is no question from the descriptions offered in the Mahabharata that the date given for the event that signaled turning of the Age is April 20, 3105 BC. It is the only date that matches the planetary configuration of the texts… [emphasis added]

Alternatively, Wikipedia says:

3102 BC—According to calculations of Aryabhata (6th century), the Hindu Kali Yuga began at midnight on 18 February 3102 BC.






The Aztec Sun Stone and 4 Ollin









The following is from azteccalendar.com


Tonatiuh, the Sun or the Sun God. Symbol of the Fifth World, the present era.

According to Aztec Mythology, there have been four historical ages, called Suns – those of earth, wind, fire and water. Each has been destroyed. The present era is that of the Sun of Movement, Ollintonatiuh. It is also known as Nahuiollin or 4-Ollin (Movement). In the famous stone of Axayacatl, as you can see on the left, Tonatiuhs face is embedded in this calendrical sign. The wings of the Ollin symbol show the calendrical signs of the past four eras. Tonatiuhs claws are aspects of the Earth Goddess, Tlaltecuhtli.

In the tonalpohualli, Tonatiuh rules over trecena Miquiztli (death). He is Lord of the Day for days with number 4 (“nahui” in Nahuatl).

The Maya Long Count End Date





interlocking cogs

December 16, 2013 (the end date) versus 13 Baktuns (a Great Cycle)

What is the “end date” or last day of the Mesoamerican Long Count calendar? December 21, 2012 is not the correct answer for a number of reasons discussed in this section. That is not the same thing as saying the GMT Correlation date is wrong. Allow me to repeat this critical point, to dispute an “end date” of December 21, 2012 is not the same thing as saying the GMT correlation date is wrong. In fact, I am convinced that the GMT correlation date is correct. Nevertheless, the correct calendar end date is December 16, 2013, which is “13 Ahau” expressed as in the Maya language. The difference between December 21, 2012 and December 16, 2013 is a misunderstanding of how the Mesoamerican Long Count calendar works as discussed in Understanding the Mechanics of the Long Count Calendar.


The Georgia Guidestones were erected in 1980, exactly 33 years before the correct Mesoamerican Long Count calendar end date in 2013.

The problem is that 13 baktuns of 144,000 days is the length of a Great Cycle, which is a division of the calendar into fifths marking major cycles of destruction equal to 432 orbits of Jupiter. 144,000 days is 400 years of 360 days, which was the length of a year when this calendar was designed sometime before February 26th, 747 BC when Mars bumped up against Earth’s magnetosphere and changed the year to 365.2422 days. We are living at the end of the last of these five Great Cycles referred to as the Fifth World.

Maintenance Note: The following (original) discussion is included more or less verbatim in Why 2017 instead of 2018? Was 2017 the “Great Mistake”? and The GMT Correlation Date.

While it requires a rudimentary understanding of the design of the Mesoamerican Long Count  calendar (discussed in Understanding the Mechanics of the Long Count Calendar), to say that December 21, 2012 (the end of 13 baktuns) is the end of the calendar is roughly equivalent of saying “2012” is a date. It is not. The month and day are missing. It is more or less the same with the Mesoamerican Long Count calendar. Only the largest cog finished turning on December 21, 2012. But the design of the Mesoamerican Long Count calendar involves three cogs. The other two cogs, more or less equivalent to our month and day, must continue turning until they too come to an end. When they do, the date is December 16, 2013.

The Wayeb and 13 Ahua glyphs have a common element (arguable an asteroid plummeting towards earth) , which I find more than a little interesting

The difference between December 21, 2012 and December 16, 2013 is comparable to saying 1999 was the end date of the twentieth century or second millennium, whereas it would be much more accurate to say that December 31, 1999 was the end. What does “1999” mean to someone trying to figure out on what day the twentieth century or second millennium ends? It ended December 31, 1999. Do you see the difference? The exact same thing happened with the Mesoamerican Long Count calendar.

I first became aware of this argument for the correct end date of December 16, 2013 while reading two obscure threads on “Godlike Productions,” which is a discussion forum for “UFOs, Conspiracy Theorists, and the Lunatic Fringe,” admittedly not a website description that readily lends itself to being a credible source for such an immensely important argument. Nevertheless, this is a singularly strong argument for a different end date than the popularly known and believed December 21, 2012. I have very carefully preserved these threads. They are exact copies, with only frivolous, irrelevant, or unsubstantial comments excluded and some very minor formatting changes for readability. This argument for a end date of December 16, 2013 is profoundly important, which is why I could not risk it being deleted from the Godlike Productions website.

Original End Date Argument (Carefully Preserved)

The strength of this argument is also based on the belief that the end date, according to ancient Maya texts, must be 13 Ahau. This is also the argument of the more respectable Carl Calleman.


The end of the second post from 2012 references the work of Susan Lynne Schwenger and suggests that she has arrived at this very same end date using an entirely different approach, but the links provided are now dead. A simple Google search provides several links which preserve her discussion of the Mesoamerican Long Count calendar end date:



This does indeed appear to be two different approaches arriving at the same conclusion, which is that the correct end date of the Mesoamerican (Mayan) Long Count calendar is actually December 16, 2013. This begs the question of why would the designers of this calendar select an end date five days before the Winter solstice? I believe this was done specifically so that we would ask this very question. Knowing the correct end date does not change the argument that not even the ancients would make such a date public. It had to be obfuscated.


Ending the Mesoamerican Long Count calendar five days before the winter solstice is an important clue that this is not in fact the actual end date. Much like five days must be aded to December 16, 2013 to arrive at the Winter Solstice, five years must also be added. Five years is the difference between 13 baktuns and 2160 orbits of Jupiter. I refer to these five years as the Great Wayeb.


Mayan shamans who are alive today have said it was always “y un poco.” They just do not know how much more time should be added. If the actual end date is somehow doubly obfuscated, an elaborate anti-cipher is required to assure people in the distant future that they are correctly interpreting the designer’s intent. After all, the future of mankind is at stake here. And the designers of the Mesoamerican Long Count calendar were most assuredly infinitely more intelligent than the Mayans. They left that anti-cipher for us.






And there is a serious  year zero problem with 2012.

A baktun (properly b’ak’tun /ˈbɑːkˌtn/;[1] Mayan pronunciation: [ɓakʼ ˈtun]) is 20 katun cycles of the ancient Maya Long Count Calendar. It contains 144,000 days, equal to 394.26 tropical years. The Classic period of Maya civilization occurred during the 8th and 9th baktuns of the current calendrical cycle. The current baktun started on — December 21, 2012 using the GMT correlation.

J. Eric S. Thompson pointed out that it is erroneous to say that a Long Count date of, for example, is in the “9th baktun”, analogous to describing the year 209 AD as in the “2nd century AD”. However, the practice is so well established among Maya epigraphers and other students of the Maya that to change it would cause more harm than its perpetuation.[2] So the current practice of referring to the current baktun as ”baktun 13” or “thirteenth baktun” may stand, even though it is properly the fourteenth baktun. Alternatively, the first baktun could instead be referred to as the zeroeth to avoid this ambiguity.  — Wikipedia





Archaeologists have found carvings in a stone staircase at the La Corona dig site in Guatemala which confirm the ‘end date’ of the Maya calendar, December 21, 2012.

A newly discovered Mayan text reveals the “end date” for the Mayan calendar, becoming only the second known document to do so. But unlike some modern people, ancient Maya did not expect the world to end on that date, researchers said.

“This text talks about ancient political history rather than prophecy,” Marcello Canuto, the director of Tulane University Middle America Research Institute, said in a statement. “This new evidence suggests that the 13 bak’tun date was an important calendrical event that would have been celebrated by the ancient Maya; however, they make no apocalyptic prophecies whatsoever regarding the date.”


An ancient Maya text has emerged from the jungles of Guatemala confirming the so-called “end date” of the Maya calendar, Dec. 21, 2012.

Considered one of the most significant hieroglyphic finds in decades, the 1,300-year-old inscription contains only the second known reference to the “end date,” but does not predict doomsday.

It is only the second known inscription which confirms this ‘end date’.

The Prophecy of Chilam Balam

This section is not yet written. There are only two sources. This needs to be much better researched and documented.

Did the Mayans walk down to the local 7-11 and buy a new Long Count calendar every 25,621.488 years, or are Maya experts who think the calendar was designed around the end date correct? This section discusses on what basis one may assume that the end of the fifth Great Cycle does in fact correspond to the end of the Fifth World.



Dec. 16th, 2013 (13 Ahau)

Katun- 144,000 days

At the end of the 13 Ahau Katun 

Hunab-ku= Galactic Center

The prophecy of Chilam Balam, the singer, of Cabal-chen, 4 Mani. (below)

On <the day> 13 Ahau the katun will end in the time of the Itzá, in the time of /

Tancah , lord. There is the sign of Hunab-ku 6 on high. The raised wooden standard shall come. It shall be displayed to the world, that the world may be enlightened, lord. There has been a beginning of strife, there has been a beginning of rivalry, when the priestly man shall come to bring the sign in time to come, lord. A quarter of a league, a league he comes. You see the mut 9-bird surmounting the raised wooden standard. A new day shall dawn in the north, in the west.

Itzamná Kauil shall rise. Our lord comes, Itzá. Our elder brother comes, men of Tantun. Receive your guests, the bearded men, the men of the east, the bearers of the sign of God, lord. Good indeed is the word of God that comes to us. The day of our regeneration comes. You do not fear the world, Lord, you are the only God who created us. It is sufficient, then, that the word of God is good, lord. <He is> the guardian of our souls. He who receives him, who has truly believed, he will go to heaven with him. Nevertheless <at> the beginning were the two-day men.
Let us exalt his sign on high, let us exalt it <that we may gaze upon it today with the raised standard. Great is the discord that arises today. The First Tree of the World is restored; it is displayed to the world. This is the sign of Hunab-ku on high. Worship it, Itzá. You shall worship today his sign on high. You shall worship it furthermore with true good will, and you shall worship the true God today, lord. You shall be converted to the word of Hunab-ku, lord; it came from heaven. Oh it is he who speaks to you! Be admonished indeed, Itzá. They will correct their ways who receive him in their hearts in another katun, lord.
Believe in my word itself, I am Chilam Balam, and I have interpreted the entire message of the true God the world; it is heard in every part of the world, lord, the word of God, the Lord of heaven and earth. Very good indeed is his word in heaven, lord.
He is ruler over us; he is the true God over our souls. /

But those to whom <the word> is brought, lord: thrice weighed down is their strength, the younger brothers native to the land. Their hearts are submerged . Their hearts are dead in their carnal sins. They are frequent backsliders, the principal ones who spread , Nacxit Xuchit in the carnal sin of his companions, the two-day rulers. crookedly on their thrones; crookedly in carnal sin. Two-day men they call them. For two days their seats, their cups, their hats. They are the unrestrained lewd ones of the day, the unrestrained lewd ones of the night, the rogues of the world. They twist their necks, they wink their eyes, they slaver at the mouth, at the rulers of the land, lord. Behold, when they come, there is no truth in the words of the foreigners to the land. They tell very solemn and mysterious things, the sons of the men of Seven-deserted-buildings, the offspring of the women of Seven-deserted-buildings, lord.

Who will be the prophet, who will be the priest who shall interpret truly the word of the book?

COPIED FROM July 4, 1776, Sirius, and the Mayan Connection

Essentially, the cycle of thirteen katuns was for the Maya a kind of mundane astrology, not an astrology of the individual, but of the society and its history. In the several books of Chilam Balam, the influences of the thirteen katuns are stated, usually as a description of historical events that occurred during previous cycles. It becomes clear to the reader, however, that the Maya always expected history to repeat itself and it is also obvious that the ancient Maya were not very optimistic about their fate. Most of these “fates” are negative, but then this may have been was how life was for them. The delineations below are a composite taken from the Book of Chilam Balam of Chumayel and the Codex Perez and the Book of Chilam Balam of Mani.

Katun 13-Ahau: This is a time of total collapse where everything is lost. It is the time of the judgment of God. There will be epidemics and plagues and then famine. Governments will be lost to foreigners and wise men, and prophets will be lost.

Comet ISON on December 16, 2013

What you are looking at here is comet ISON, Venus (to the left), and Earth. This actually happened and the date was December 16, 2013, precisely the date I argue was the actual “end date” or last day of the Maya Long Count calendar (though I did not know this at the time). The distance from both Venus and Earth to Comet ISON is precisely 0.51 AU (astronomical units).

Comet ISON triangle

I do not remember the exact day I first saw what you can see in the above image. I was using the “Comet ISON model” developed by Solar System Scope. As I moved the model slowly back and forth through time, I noticed something that shocked me. Comet ISON, Venus, and Earth were going to form a perfect equilateral triangle (not unlike the Pythagorean tetractys) in space with sides equal to 0.51 AU. This is equivalent to the angle of the sides of the Great Pyramid of Giza. I intuitively knew at the time that this was some kind of a message, but from who? And why?

First, here is some background information from a source you can always trust. (These are real scientists.)

Comet ISON Mysteries Continue | Space News from the YouTube channel


Now before I go any further, it is important to realize that comet ISON was a rare occurrence of a comet originating from deep space. This is why there was a NASA Comet ISON Observing Campaign (CIOC). You can click on the following image to read the article written by Matthew Knight:

NASA Comet ISON Observing Campaign-25

I sent an email inquiry to the astronomers who created Solar System Scope. They assured me that their Comet ISON model used the very latest JPL (ephemeris) data to compute the comet’s orbital path. This is not guess work; this is a very exacting science. To be perfectly blunt, I believe that Comet ISON was deliberately set into motion and precisely guided for perhaps an extended period of time for the purpose of confirming the Mesoamerican (Mayan) Long Count calendar end date of December 16, 2013 by referencing the slope of the Great Pyramid of Giza. Sounds crazy, no?

As I said above, I first saw this back in 2012 as it was happening. What I did not know at the time was that it was occurring on the correct end date of the Mesoamerican Long Count Calendar. I am not a statistician, but if such comets appear on average only once every two hundreds years or more as documented in the above article, the odds of it forming a triangle with two 0.51 AU (51 degree) sides on the last day of the Mesoamerican Long Count calendar which began so many thousands of years ago must be astoundingly high.



Comet ISON was a wakeup call. A reminder that the Mesoamerican Long Count calendar is everything everyone thought it was prior to December 21, 2012. For anyone listening, it is also a message that we are not alone, and never have been.


We are not alone!


The remainder of this article documents the precise timing of this event. At precisely 4:10 PM on December 15, 2013, Venus approached ISON to a distance of 0.51 AU:

Venus reaches 0.51 AU from ISON-19

Late in the same day at precisely 8:32 PM Earth approached to within 0.51 AU of Comet ISON. So by late in the day before the end of the Mayan Long Count Calendar both Earth and Venus form a triangle with ISON at the top and both planets at a distance of 0.51 AU equal to the angle of the sides of the Great Pyramid of Giza.

Earth reaches 0.51 AU from ISON-15

Earth was the first to move outside of the 0.51 AU range of ISON on December 16, 2013 at precisely 1:16 PM

Earth leaves 0.51 AU from ISON-21

Venus stayed in the 0.51 AU range of ISON for a couple of days until December 18 at precisely 1:36 AM.

Venus leaves 0.51 AU from ISON-23
