The significance of this day
Aztec facts
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.
This is the third of the five unlucky days (nemontemi) at the end of a year (xihuitl). It is better not to carry out any activity during these unfortunate and useless days.
Day Miquiztli (Death) is governed by Tecciztecatl, the Moon God, as its provider of tonalli (Shadow Soul) life energy. It is a good day for reflecting on your priorities in life, a bad day for ignoring possibilities. It is a day of transformation, signifying that briefest moment between old endings and new beginnings.
The thirteen day period (trecena) that starts with day 1-Cipactli (Crocodile) is ruled by Tonacatecuhtli, Lord of Nurturance, the primordial god of creation and fertility. Cipactli is god of the land, the great earth monster, floating on the sea of stars. This is the first trecena of the sacred year. The 13 days of this trecena are governed by the primordial urge to create order out of chaos. The three means by which the Old Ones established order are still our most important treasures: speech, agriculture, and the family. The lineage of thought runs from seed to fruit to seed: these are good days to participate in the community; bad days for solitude.
