Maya Long Count Calendar

The Mayan Long Count Calendar is a linear count of days much like the Gregorian Calendar. These pictures are Coba Stela 1 with the inscribed Long Count date of 13.13.13.13.13.13.13.13.13.13.13. 13.13.13.13.13.13.13.13.13.0.0.0.0 (The twenty 13's are most visible on the upper leftmost portion of the outline and stela).

The Maya Long Count is a positionally represented linear count of days and in short form can represent a day as 13.0.0.0.0 This is very similiar to the Gregorian Calendar as it is also a positionally represented linear count of days in which a day can be represented as 12.21.2012

The Long Count works on a modified vigesimal system (base-20). Each position increments to the next position (the leftmost position represents the higher numbers as opposed to the Gregorian Calendar) once the position reaches 20 except for the second position which rotates up on 18.

The positional markers of the Gregorian calendar are called days, months and years and we can multiply each by its corresponding values (with special considerations) to get the number of days that have past since the inception date of the calendar. The same holds true for the Long Count.

The positional markers (following the highest marker left notation) of the Long Count date 13.0.0.0.0 are called:

13

0

0

0

0

Baktun

Katun

Tun

Uinal

Kin



You can figure out the date with the following the table below:

Baktun

= 20 Katun

Katun

= 20 Tun

Tun

= 18 Uinal

Uinal

= 20 Kin

Kin

= 1 Day
