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.
