The Calendar Round is a system used by the ancient Maya civilization to track time. It combines two different calendars: a 260-day ritual calendar called the Tzolk'in and a 365-day solar calendar known as the Haab'. By overlapping these two cycles, the Calendar Round creates a unique 52-year cycle, after which the same date combination repeats.
Each day in the Calendar Round is identified by a specific number and name, making it essential for scheduling religious ceremonies and agricultural activities. This intricate system reflects the Maya's deep understanding of astronomy and their connection to the natural world, showcasing their advanced knowledge of timekeeping.
