The religious calendar told the Maya and Aztec when to consult the gods.
The religious calendar contained 260 days, with 13 groups of 20 days. The Aztecs called it the tonalpohualli, or the “count of days.”
Different days belonged to different gods, so days could be good or bad depending on which god's day it was. A child born on a bad day received its name on a good day, to rule out all harmful effects of the bad day.
