Robert Wauchope on the Use of Multiple Calendars in Ancient Mesoamerica

  

One of the diagnostics of classic Maya culture was its system of permutating calendars. The ancient Maya seem to have been fascinating, even obsessed, with recurring cycles of time, some of them ceremonial in origin, having no apparent correspondence to anything in nature; some recording such natural phenomena as the solar year, lunations, eclipses, and other regularities of heavenly bodies as viewed from earth. . . . One of these cycles as the Sacred Round (tzolkin) of 260 days, consisting of two recurring cycles of different length, the first being of 13 days, recorded as numbers, and the second being of 20 days, recorded as names. A second cycle was the solar year or, more properly, the “vague year” of 365 days, which was divided into 18 divisions of 20 days each (popularly referred to today as “months”) plus a 5-day appendix at the end of the year, this last considered a dangerous and unlucky period. The completion of these two cycles, the Sacred Round and the Vague Year, coincided every 52 vague years (18,980 days). This larger cycle is called the “Calendar Round.” Carved monuments (stellate) were frequently erected at Calendar Round and other intervals.
