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 Ehecatl (Wind) is governed by Quetzalcoatl as its provider of tonalli (Shadow Soul) life energy. Ehecatl is a bad day for working with others. Its influences are inconstant and vain. A good day to root out bad habits.
The thirteen day period (trecena) that starts with day 1-Cozcacuauhtli (Vulture) is ruled by Xolotl. This trecena signifies the wisdom and freedom of old age; it represents the path of the setting sun. While the way of the warriorpoints to the relationship between predator and prey, this sign points to to the Third Way, which is neither: these are 13 days set aside to perfect the Way of the Scavenger. While the young heart must strategize between offense and defense, the old heart float like the clouds, stooping to earth only to take what no one else wants. These are good days for disengaging; bad days for participating.
