The Mayans weren't the first ever to use a calendar -- there were ancient calendars in use throughout civilizations worldwide -- but they did create four different calendars. Depending on their needs, the Mayans used different calendars to record each event, either alone, or in some combination of two calendars.Mesoamericans began writing during the mid-Pre-classic period. The Mayans were the first to keep any sort of historical record, and the beginnings of the calendar were born. The Mayans used stelae, or stone monuments, to carve their civil events, calendars and astronomy knowledge. They also recorded their religious beliefs and mythology on pottery.
