Maya Calendar is a small widget that will show you the Long Count and the Calendar Round (Tzolkin and Haab) in both authentic and modern notation. As a bonus it counts down to the end of the 13th Baktun (December 21, 2012).
The classic Maya produced extremely accurate astronomical observations. In common with the other Mesoamerican civilizations, the Maya utilized a highly accurate measure of the length of the solar year, far more accurate than that used in Europe.
The Long Count calendar identifies a date by counting the number of days from August 11, 3114 BCE. Long Count days are written in a modified base-20 scheme. Thus day 0.0.0.1.5 refers to day 25 after the starting date.
However, since the second digit (from the right) only counts to 18 before resetting to zero, 0.0.1.0.0 does not represent 400 days, but rather only 360 days.
The Tzolk'in is a calendar with a period of 260 days. It is of great antiquity. The Tzolk'in combined with the Haab', a 365-day calendar, to form a synchronised cycle lasting for 52 Haabs, called the Calendar Round.
