The significance of this day
Day Mazatl (Deer) is governed by Tlaloc, God of Rain and Thunderstorms, as its provider of tonalli (Shadow Soul) life energy. Mazatl is the day of the hunt. It is a good day to stalk your quarry, a bad day to be stalked. Mazatl is a day for breaking old routines and to pay close attention to the routines of others. This is a day for doubling-back on your tracks.
The thirteen day period (trecena) that starts with day 1-Miquiztli (Death) is ruled by Tonatiuh. This trecena signifies the vast cosmological forces at play in the lives of human beings. These 13 days are all influenced by transformative powers of unknown dimension, origin and intent. The days of this trecena often pass by unnoticed since they are not remarkable until the elementals turn their attention to this place, the first of the thirteen skies; when this occurs, though, the whole of the world changes. It is during these days that the song of the Old Ones may best be heard. These are good days to fulfill old obligations; bad days to go back on one's word.
Elton John was born on day 2-Mazatl.
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).
