2012 – THE MAYA CALENDAR AND THE “END OF TIME”
Background
The Maya civilization, which flourished in southern Mexico, Guatemala, and Belize from about 2000 BC to 1000 AD, had a system of three calendars (fully described for the cover picture of Astronomical Calendar 2010):
- The Long Count, or numbering of days from (probably) 3114 BC Sep. 7: 20 kin (days) make a winal; 18 winal, a tun (360 days); 20 tun, a katun; 20 katun, a baktun (144,000 days, about 394 years). Even larger units were not actually used in the expression of dates: 20 baktun make a piktun (2,880,000 days); 20 piktun, a kalabtun; 20 kalabtun, a kinchiltun; 20 kinchiltun, an alautun (23,040,000,000 days, or around 63 million years).
- Haab, in which a 365-day year was divided into 18 20-day units with names (Pop, Wo, Zip, Zotz, Tzek, Xul, Yaxkin, Mol, Chen, Yax, Zak, Keh, Mak, Kankin, Muwan, Pax, Kayab, Kunku) and a 5-day 19th (Wayeb).
- Tzolkin, in which each day had one of 13 numbers, and also one of 20 names (Imix, Ik, Akbal, Kan, Chikchan, Kimi, Manik, Lamat, Muluk, Ok, Chuwen, Eb, Ben, Ix, Men, Kib, Kaban, Etznab, Kawak, Ahau), so that any one combination, such as 1 Imix, came around after a cycle of 260 days.
Some of these numberings started not with 1 but with zero; thus katun 19 is really the 20th in its baktun, and is followed by katun 0, which is the first in the next baktun.
The Scare
Chances are you have heard that the Maya predicted the end of the world on December 21, 2012. This was the day when the Maya Long Count calendar cycle came to completion. You may have also heard that the world was predicted to be destroyed by an earthly or cosmic catastrophe. We know these predictions didn’t come true – but were any based on fact, or total fiction?
December 21, 2012 marked the end of an important cycle in the Maya Long Count calendar. This cycle is composed of 13 periods, called baktun, of 144,000 days each.
- This 13-baktun cycle began on the Long Count calendar date 13.0.0.0.0 4 Ajaw 8 Kumk’u, and spans 5,125.366 solar years. Stela C (left) records this date, considered by the Maya to be the creation date of the current or 4th era.
- The monument is at the archaeological site of Quiriguá, Guatemala.
- This creation date corresponds to August 11, 3114 BCE. Monument 6 (right), from the archaeological site of Tortuguero in Tabasco, México, records the only known Maya inscription of the end date of the 13-baktun cycle.
- This end date, 13.0.0.0.0 4 Ajaw 3 Kank’in, corresponds to December 21, 2012.
There is no evidence in these inscriptions, or in any other record, that the ancient Maya thought that the Long Count calendar would imply some kind of catastrophic “end.” These predictions were unfounded and are not shared by the Maya people.
What does this mean? The Long Count rolls into “a string of zeros, like the odometer turning over on your car,” as E.C. Krupp put it in his amusing article about “The Great 2012 Scare,” for the November 2009 issue of Sky & Telescope. This is the end of one baktun and the beginning of another; so its component katuns, tuns, winals and kins all start again at 0. According to some authorities, the first baktun was 0, and the baktun now ending is 12; according to others it is 13. Either way, it is the 13th since the start-date of the Long Count.
