Some archaeologists think that the Olmecs, who were brilliant astronomers, would have created the first calendar in the Americas. It was taken up and perfected by civilizations like the Maya, which came after the Olmecs. In this solar calendar, the year was divided into 18 months of 20 days, with a final period of 5 days, for a total of 365 days. A sacred calendar of 260 days was also used and linked to the solar calendar. Together they made up a 52-year cycle.
