Scholars have found the oldest known Maya calendar in a pre-Hispanic archaeological complex in San Bartolo, Guatemala, inside the Las Pinturas pyramid.

The calendar was found marked 300-200 B.C.E., making it the earliest evidence of the Mayan calendar. 

The site where the calendar was found has been a source of findings for 21 years now. In the past, archaeologists have found murals and artwork dating to around 100 B.C.E. This year, archaeologists identified a “7 Deer” glyph on two pieces of white plaster fallen from one of the murals. The “7 Deer” glyph represents one of the 260 days of the Mayan calendar, also known as tzolk’in.
