The significance of this day
Aztec facts
In the years after the conquest of Mexico, the xiuhpohualli (solar calendar) became tied to the Julian calendar as used by the Spaniards. This effectively introduced a leap year to the Aztec calendar every four years (this site provides the pre-conquest calendar).
Day Cipactli (Crocodile) is governed by Tonacatecuhtli, Lord of Nurturance, as its provider of tonalli (Shadow Soul) life energy. Cipactli is an auspicious day, signifying advancement and honor. It depicts energy and work, rewards and recognition. A good day for beginnings.
The thirteen day period (trecena) that starts with day 1-Tecpatl (Stone Knife) is ruled by Mictlantecuhtli, Lord of the Region of the Dead, god of death. This trecena signifies an ordeal or trial that pushes one to the very threshhold of endurance: it forebodes an abrupt change in the continuity of things. These are 13 days influenced by the sun, which is a symbol of death: the stars are the warriors of the past and the sun is the gateway of that transformation. The sun is singing fire while the Evening Star guides it through the Region of the Dead: the combined efforts of the elementals are focused on producing a permanent change of heart. These are good days to shed old skins; bad days to cling to what is already known.
