The Mayan calendar is a system of calendars used by the Maya civilization of pre-Columbian Mesoamerica. The calendar is based on a combination of a 260-day sacred calendar, known as the Tzolk’in, and a 365-day civil calendar, known as the Haab’.
The Mayan calendar has been used for centuries to track time and predict events. It is still used by some Maya people today. In recent years, there has been some interest in using the Mayan calendar to predict the gender of babies born in 2025.
