The two most widely used calendars in pre-Columbian Mesoamerica, were the 260-day Tzolk'in and the 365 day Haab'.
The equivalent Aztec calendars are known in Nahuatl as the tonalpohualli and Xiuhpohualli.
The authorities disagree on what 220.127.116.11.0 corresponds to in our calendar.
I have come across three possible equivalences: Assuming one of the first two equivalences, the Long Count will again reach 18.104.22.168.0 on 21 or 23 December AD 2012 - a not too distant future.
Anyone born on those days was "doomed to a miserable life." The years of the Haab calendar are not counted.
The length of the Tzolkin year was 260 days and the length of the Haab year was 365 days.
This 260-day cycle also had good-luck or bad-luck associations connected with each day, and for this reason, it became known as the "divinatory year." The "years" of the Tzolkin calendar are not counted. It consisted of 18 "months" of 20 days each, followed by 5 extra days, known as Uayeb.

The combination of a Haab' and a Tzolk'in date identifies a day in a combination which does not occur again for 18,980 days (52 Haab' cycles of 365 days times 73 Tzolk'in cycles of 260 days, approximately 52 years), a period known as the Calendar Round.
