Aztec and Maya Calendar

Did you know?

The Aztecs did not use a leap year correction but they knew the length of a solar year is neither 365 nor 365.25 days. Presumably they kept some count of days to register astronomical events but no evidence of an Aztec Long Count exists.

The significance of this day

Day Quiahuitl (Rain) is governed by Tonatiuh, the Sun God, as its provider of tonalli (Shadow Soul) life energy. Quiahuitl is a day of relying on the unpredictable fortunes of fate. It is a good day for traveling and learning, a bad day for business and planning.

This is the first of the nemontemi (five unlucky days) at the end of a xihuitl.

The thirteen day period (trecena) that starts with day 1-Malinalli (Grass) is ruled by Mayahuel, Goddess of the Maguey and Pulque. These are 13 days of intoxication, infatuation, excitement and passion: it is a time of excesses, when moderation is impossible, and so is often a time of disastrous consequences. This trecena signifies those times when we are incapable of protecting ourselves from high emotions. It is a time when affairs of war and affairs of the heart are born without thinking. These days are clouded in confusion: only the most self-disciplined warrior can suffer an excess of success without incuring sudden loss. These are good days to bind the community together; bad days to sow discord and discontent.
