Correlations between Western calendars and the Long Count calendar

There have been various methods proposed to allow us to convert from a Long Count date to a Western calendar date. These methods, or correlations, are generally based on dates from the Spanish conquest, where both Long Count and Western dates are known with some accuracy.

The commonly-established way of expressing the correlation between the Maya calendar and the Gregorian or Julian calendars is to provide number of days from the start of the Julian Period (Monday, January 1, 4713 BCE) to the start of creation on 0.0.0.0.0 (4 Ajaw, 8 Kumk'u).

2012 and the Long Count

According to the Popol Vuh, a book compiling details of creation accounts known to the K'iche' Maya of the Colonial-era highlands, we are living in the fourth world. The Popol Vuh describes the first three creations that the gods failed in making and the creation of the successful fourth world where men were placed. In the Maya Long Count, the previous creation ended at the start of a 13th b'ak'tun.

The previous creation ended on a long count of 12.19.19.17.19. Another 12.19.19.17.19 will occur on December 20, 2012, followed by the start of the fourteenth b'ak'tun, 13.0.0.0.0, on December 21, 2012.


Significance within the New Age movement

Three figures within the New Age, the artist and theorist José Argüelles, John Major Jenkins, Daniel Pinchbeck and the late ethnobotanist and psychonaut Terence McKenna, have publicized theories concerning the significance of the end of the cycle. (They arrived at their conclusions separately from one another). They have jointly inspired a number of articles and books that this will be the end of this creation, the next pole shift or, as McKenna speculated in his theories, the end of history and events as "novel" as the origin of life on Earth, which we could not possibly imagine. Jenkins has focused on the occurrence of a Galactic Alignment in the "era of 2012". Other, more mundane speculations involve a worldwide catastrophe, such as a pole shift. The idea of the significance of the date has also increasingly passed into popular culture.

Beyond 2012

Maya stelae occasionally show dates beyond 2012. Most of these are in the form of "distance dates", where a Long Count date is given with a distance date to be added. For example, on the Tablet of Inscriptions from Palenque the following Long Count date was found: 9.8.9.13.0 8 Ahau 13 Pop (March 24, 603 Gregorian) with a distance date of 10.11.10.5.8. The resulting date is given as 1.0.0.0.0.8 5 Lamat 1 Mol, or October 21, 4772 – almost 3,000 years into the future. The king Pacal of Palenque predicted that on this date the eightieth Calendar Round anniversary of his accession will be celebrated, suggesting he did not believe the world would end in 2012.

Despite the publicity generated by the 2012 date, Susan Milbrath, curator of Latin American Art and Archaeology at the Florida Museum of Natural History, stated that "We [the archaeological community] have no record or knowledge that [the Maya] would think the world would come to an end" in 2012.

"For the ancient Maya, it was a huge celebration to make it to the end of a whole cycle," says Sandra Noble, executive director of the Foundation for the Advancement of Mesoamerican Studies, Inc. in Crystal River, Florida. To render December 21, 2012, as a doomsday or moment of cosmic shifting, she says, is "a complete fabrication and a chance for a lot of people to cash in."

"There will be another cycle," says E. Wyllys Andrews V, director of the Tulane University Middle American Research Institute (MARI). "We know the Maya thought there was one before this, and that implies they were comfortable with the idea of another one after this."
