Mayan Calendar
The Mayan Calendar, part of the larger Mesoamerican Long Count calendar, is a system of timekeeping that was used by the Mayans of pre-Columbian Mesoamerica. Developed by the 1st century BC, it was used until the Spanish Conquest of the 16th century AD.
History of the Mayan Calendar
The Mayan Calendar is comprised of three primary cyclical calendars, each representing a different unit of time:
- The Haab, or “year count,” is a 365-day solar calendar.
- The Tzolkin, or “day count,” is a 260-day sacred calendar.
- The Long Count is a vigesimal (base-20) calendar that records very long periods of time.
These three calendars interlock to create a larger cycle, known as the Calendar Round, which occurs every 52 Haab years (or 18,980 days). The Calendar Round was a critical element of Mayan culture, as it was used to schedule religious ceremonies, agricultural activities, and other important events.
