In the Mesoamerican calendars, Calendar Round dates are composed by interlacing the dates of a 260-day period (Tzolk'in in the Maya Calendar, Tonalpohualli in the Aztec calendar) with dates from a 365-day period (known in the Maya language as the Haab' and in Nahuatl as Xiuhpohualli). One Calendar Round cycle thus includes 18980 distinct dates and lasts approximately 52 years (the least common multiple of 260 and 365 is 18980). A typical Calendar Round date such as 8 Cauac 13 Zip shows the day 8 Cauac of the Tzolk'in cycle with 13 Zip month date of the Haab'. A third calendar, the Hajj, was based a period of 28 Days, which is one complete lunar cycle. See alsoExternal links
