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 Ocelotl (Jaguar) is governed by Tlazolteotl as its provider of tonalli (Shadow Soul) life energy. Ocelotl is a good day for doing battle. It signifies power, valor, and reckless abandon in the face of danger. This is a day of the Warriors of Tezcatlipoca, those who willingly sacrifice their lives to keep the flame of the Old Ones burning forever.
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.
