The Mayan Calendar’s 52-Year Cycle

“The Mayan Calendar’s 52-Year Cycle: The Mayan’s fifty-two-year cycle is created by observing how the combination of their two simultaneous calendars—the 260-day-long Tzolk’in fertility calendars and 365-day-long Haab solar year—fitted into a naturally repeating cycle over a fifty-two year time span.”
