The cycles of Venus were brought into this calendar scheme by a fortunate relationship with the double Calendar Round. Venus goes through periods as evening star and morning star, and will rise in the east as morning star every 584 days. The Mesoamerican astronomers noticed that five of these Venus periods equal eight years. In other words, Venus will rise as morning star five times every eight years, returning to the same place in the zodiac. In effect, Venus traces a five-pointed star around the zodiac during this time, explaining the ancient Babylonian association of Venus with pentagrams. All of the cycles of sun, tzolkin, and Venus are completed in two Calendar Rounds, just under 104 years. This period is called the Venus Round.
The 52-haab Calendar Round is a complete system of timekeeping and was used throughout Mesoamerica in ancient times. In fact, the Aztecs used it in their New Fire ceremony, in which the Pleiades were observed passing through the zenith at midnight at the end of a Calendar Round period. In my 1998 book
Maya Cosmogenesis 2012
I reconstructed how this tradition was designed to track the celestial shifting called the precession of the equinoxes. The New Fire ceremony and Calendar Round periods were essential to the Central Mexican understanding of World Ages.
The Maya used this system but also developed their own unique timekeeping system, the Long Count. This is the calendar that targets 2012 as the end of a vast cycle of time, a key concept in the Maya doctrine of World Ages. The Long Count basically utilizes five place values. It is often said that it is a base-20 system, which is generally true, but in fact two of the five levels do not follow the base-20 math:
1 day = 1 Kin (day)
20 days = 1 Uinal (vague month)
360 days = 1 Tun (vague year)
7,200 days = 1 Katun (19.7 years)
144,000 days = 1 Baktun (394.26 years)
13.0.0.0.0 Creation Text from Quiriguá, August 11, 3114 BC. Drawing by the author
Thirteen Baktuns equal 1,872,000 days, which is one “era” or World Age cycle (5,125.36 years). Notice that the Baktun is multiplied by 13 rather than 20 to reach to World Age cycle, and the Uinal is multiplied by 18 rather than 20 to reach the Tun. We know that the 13-Baktun period ends on December 21, 2012, because, as we saw in Chapter 1, scholars have verified Goodman’s work that accurately correlated our Gregorian calendar with the Maya Long Count.
A date in the Long Count utilizes “dot and bar” notation, in which a dot equals one and a bar equals five. A typical date on a carved monument is pictured to the left.
You can see two bars and three dots in the upper left, next to a Baktun glyph. There are no dots or bars in the following glyphs for Katun, Tun, Uinal, and Kin, because those values are zero in this example. Next follows the tzolkin date, 4 Ahau (four dots next to the Ahau day-sign). And finally, in the lower left, 8 Cumku in the haab calendar. The final glyph block contains the event: “the image was made to appear.”

Scholars have simplified the notation so that a Long Count date written 9.16.4.4.1 means that 9 Baktuns, 16 Katuns, 4 Tuns, 4 Uinals, and 1 day have elapsed since the zero day of the Long Count, which the correct correlation fixes at August 11, 3114 BC. The “zero” date is written 0.0.0.0.0 but can also be written 13.0.0.0.0 (as the completion day of the previous cycle). The “end-date” of a 13-Baktun cycle is thus written 13.0.0.0.0. The use of the term “end-date” gives rise to the mistaken notion that the Maya calendar ends in 2012. But Maya time is cyclic, and it should go without saying that time continues into the next cycle. We use similar conventions in our language when we speak of “the end of the day,” but we don’t expect the world to end at midnight.
After decades of testing, the correlation question was finally settled by 1950. The result was that the 13th Baktun would end on December 21, 2012, on the tzolkin day 4 Ahau. This date in the tzolkin confirmed the surviving day-count in highland Guatemala, and also validated the carvings in the archaeological record called Creation monuments, which always correlate 13.0.0.0.0 with 4 Ahau.
The correlation issue is settled, and in my experience confusion arises only among those who have not studied or understood the topic. Thus, many popular books dismiss or neglect the correct correlation and instead proceed to invent new correlations, including completely fabricated day-counts as well as alternate end-dates. A great deal of unity could be achieved if researchers and writers would understand and heed the fundamentals of the Maya calendar. A primary fact that needs to be appreciated is what I call “the equation of Maya time,” which is this: 13.0.0.0.0 = December 21, 2012 = 4 Ahau.
16
In addition to these systems, the Maya also tracked the 9-day cycle of the Lords of the Night, as well as an 819-day cycle that involves Jupiter. Even a basic introduction to the Maya calendar can get quite complex. For the purpose of understanding 2012, one first needs to know that December 21, 2012, is the end of the 13-Baktun cycle in the Long Count calendar, and in Maya philosophy the 13-Baktun cycle equals one “World Age.” Furthermore, it is important to clarify that December 21, 2012, is not the invention of imaginative modern writers but is a true and established artifact of the Maya philosophy of time.
THE CLASSIC PERIOD: THE LONG COUNT IN ITS PRIME
The way in which the Long Count appears in hieroglyphic texts reveals its multifarious uses. It provided a sequential day-count from the zero date baseline. It provided interval calculations between two dates, sometimes tens of thousands of years apart. It was a framework for astronomical calculations. Solstice and equinox dates fall within the framework of the Long Count in a predictable pattern, suggesting that it incorporated an accurate tropical year calculation, which modern science places at 365.2422 days.
17
Three Katuns in the Long Count equal 37 Venus cycles of 584 days. Thus, if a Venus event, such as a first appearance as morning star, happened on 9.11.0.0.0 in the Long Count, Maya astronomers were on the alert for the same event three Katuns later, on 9.14.0.0.0.
Let’s look at an early Classic Period inscription, from Tikal Stela 31. In this case it’s a retrospective date, made by a ruler named Stormy Sky (Siyaj Chan K’awil II) recalling his grandfather’s accession to kingship on 8.18.15.11.0 (November 25, 411 AD). Maya scholars Linda Schele and David Freidel noted that Jupiter and Saturn were in conjunction on this date, precisely when Venus had reached its evening star “station” (stationary between forward and retrograde motions).
18
Maya scholar Michael Grofe pointed out to me that the date was also within a few days of a visible solar eclipse.
19
The Maya would have expected this Venus station to happen again three Katuns later, on 9.1.15.11.0. Apparently, Stormy Sky’s grandfather selected the date of his coronation to correspond to these celestial events, as it would confer upon him a special relationship with the sky deities.
This Long Count example didn’t occur on a period ending, such as a Tun ending or a Katun ending. If celestial events occurred perfectly on one of these period endings, future events would more easily fit into the Long Count’s predictive framework. For this, we can look at the Long Count date 9.14.0.0.0—the completion of the 14th Katun of the 9th Baktun. Corresponding to December 3, 711 AD, this particular Long Count period ending is found at Copán, Tortuguero, Tikal, Calakmul, and other sites, suggesting it had a meaning with universal appeal. We should immediately suspect that some unusual astronomy was happening on that date, and indeed it was. First, we have the first appearance of Venus as evening star. On Copán Stela C, which contains this Long Count date, the ruler 18 Rabbit has the Venus emblem in his headgear. Also on this date, the sun was aligned with the dark rift. The popularity of this date may be rooted in this astronomical occurrence, since it evokes the alignment that falls on the cycle ending in 2012 (sun in the dark rift,
on the solstice
).
Long Count dates often seem intended to highlight Jupiter and Saturn events, either conjunction, stations, or alignments with sidereal features such as Antares, the Pleiades, or the dark rift in the Milky Way. Research by Maya scholar Susan Milbrath showed that the Katuns of the Long Count were used to track Saturn and Jupiter events, such as stations and maximum elongations.
20
Following the work of Floyd Lounsbury, who showed that the deity named Kawil was related to the planet Jupiter, Milbrath tracked the astronomy connected with Kawil-related Long Count dates in the inscriptions, and found definite patterns involving not only Jupiter but Saturn. Both planets can take on the role of Kawil, the serpent-footed lightning deity, often at Katun endings or midpoints. This is because the Jupiter-Saturn conjunction cycle is just under 20 years, and the Katun period is 19.71 years. Classic Period sites such as Tikal, Yaxchilán, and Copán were particularly interested in how the Long Count provided a framework for planetary astronomy.
In the far north at Chichén Itzá, a renaissance occurred in the early ninth century when Central Mexicans flooded into Yucatán. They brought with them traditions such as the New Fire ceremony and a unique blending of Maya and Central Mexican culture occurred. The Long Count already had a long history of use in Yucatán, at sites such as Uxmal, Ek Balam, and Coba, and there was an effort to integrate the Calendar Round system and the Long Count. The Baktun ending of 830 AD may have signaled a new era at Chichén Itzá, triggering the construction of its most enduring monuments, the Great Ballcourt and the Pyramid of Kukulcan.
The famous Long Count date at Coba is interesting because it takes the Long Count far beyond the level of the Baktun. Most dates in the Long Count use only the first five place value levels, but it theoretically can be extended indefinitely. The Coba date is basically the same date as that in the Creation Texts found elsewhere, which identify the end of the last era of 13 Baktuns on August 11, 3114 BC. This is usually written 13.0.0.0.0, but at Coba the previous cyclic periods are also given, such that we have a total of nineteen levels above the Baktun, thousands of times larger than modern science’s estimate for the age of the universe: 13.13.13.13.13.13.13.13.13.13.13.13.13. 13.13.13.13.13.13.13.0.0.0.0. As Anthony Aveni said, it seems that a Baktuno maniac was set loose on this stone. Much has been made of this representation of the Long Count. Some have suggested that it renders the 13-Baktun cycle meaningless. But this is like saying that century periods in our own calendar render the decade periods meaningless.
A distinction must be made between practical calendrics, in which the 13-Baktun period was a standardized doctrine, and theoretical mathematics. The Maya were apparently fond of generating huge numbers, which may have been attempts to find the grand number that would unify all the astronomical cycles. Greek mathematicians attempted the same thing as they grappled with the duration of the Great Year—it was supposed to be a harmonious 36,000 years, according to Plato, but the discovery of the great cycle of the precession of the equinoxes suggests a figure thousands of years less. Perhaps the Maya intended these huge numbers to represent, in a very general sense, the awesome immensity of the universe.
Coba doesn’t disqualify the importance of the 13-Baktun period. In fact, it can be added to the many other examples that point to 13.0.0.0.0, 4 Ahau 8 Cumku, August 11, 3114 BC. There are many examples of this era inauguration being alluded to with only the Calendar Round position. For example, on the famous Vase of the Seven Lords, we see Creation imagery and the date 4 Ahau 8 Cumku. This tzolkin-haab combination corresponds to a period ending in the Long Count very rarely, and that’s how scholars determine it to be a reliable shorthand for the full 13.0.0.0.0 date. Suffice it to say that the Creation Mythology’s “three-stone” symbolism itself was used as a shorthand for the 3114 BC date.
21
This practice has important ramifications for understanding how the Maya referenced the 2012 date in their hieroglyphic texts.
Critics have often stated that there are no dates recorded in the inscriptions that point directly to the cycle ending in 2012. This is not true, as we have an important date from Tortuguero, a kingdom near Palenque, that has far-reaching implications. In addition, as we’ll see in Chapter 7, secondary references to the astronomical alignment of era-2012 are found in the inscriptions, just as secondary references to 3114 BC are common. It is this new perspective on textual evidence for 2012 being an intentional and important concept in ancient Maya cosmology that constitutes a very promising new tool for identfying 2012 references in the inscriptions.
The Long Count served as a framework for building dedications, anniversaries of important events in a king’s life, and aided both astronomical calculations and shamanic prophecies. Period endings were treated as important junctures and involved sacrifice and renewal. Maya scholar Dennis Puleston suggested that the Baktun ending of 830 AD may have instigated a breakdown for some Maya cities, a fatalistic expectation that a phase of their existence as a civilization was coming to an end.
22
The old Janus-face of cycle endings may have been just as perplexing for the Maya as it is for us today, as the dissolution of one era blends with the birth of a new one. Something drastic definitely occurred around the end of Baktun 10 in 830 AD, which signaled the beginning of the end for the Classic Maya civilization.
