Scientists Finally Solved the Mystery of How the Mayan Calendar Works
We were thinking too small all along.

The Mayan calendar’s 819-day cycle has confounded scholars for decades, but new research shows how it matches up to planetary cycles over a 45-year span. That’s a much broader view of the tricky calendar than anyone previously tried to take.
In a study published in the journal Ancient Mesoamerica, two Tulane University scholars highlighted how researchers never could quite explain the 819-day count calendar until they broadened their view.
“Although prior research has sought to show planetary connections for the 819-day count, its four-part, color-directional scheme is too short to fit well with the synodic periods of visible planets,” the study authors write. “By increasing the calendar length to 20 periods of 819-days a pattern emerges in which the synodic periods of all the visible planets commensurate with station points in the larger 819-day calendar.”
That means the Mayans took a 45-year view of planetary alignment and coded it into a calendar that has left modern scholars scratching their heads in wonder.
While ancient Mayan culture offered various calendar types, the one that baffled scholars the most was this 819-day calendar discovered in glyphic texts. Researchers have long believed this calendar was associated with planetary movements, especially the synodic periods—when a planet appears visually to return to the same location in the sky, as seen from Earth—of key planets. However, each planet moves quite differently and matching up multiple planets into an 819-day span didn’t seem to make sense.
