Number of Mayan calendars
How many Mayan calendars are there?
It is widely known the fact that the ancient Mayas invented a calendar of remarkable accuracy and complexity. The main idea is that the Mayans used several calendars at the same time. This signifies that depending on how you count, they had 3, 4, 5 or even more calendars all running side-by-side. Needless to say, each one was counting off the number of days independently of the others. Not too many people know the fact that the Mayan calendar is based on the idea of cycles.
