There are three main Maya calendars: the 260 day ritual calendar called "Tzolk'in", the 365 day "Haab"', and the "Long Count". Approximately 52 years pass before the Haab and Tzolkin calendars converge and are back in the same alignment. This is called the Calendar round. The Tzolk'in is still in use today by the Ixil, Kek'chi and Quiche peoples of the Guatemalan highlands.
