The significance of this day
Day Ozomahtli (Monkey) is governed by Xochipili, the Flower Prince, as its provider of tonalli (Shadow Soul) life energy. Ozomahtli is a day for creating, for play, for celebrating. A good day for lightheartedness, a bad day for seriousness. Ozomahtli is a warning about how easily the noble person can be trapped by the lures of public life.
The thirteen day period (trecena) that starts with day 1-Itzcuintli (Dog) is ruled by Xipe Totec, Lord of Shedding, god of seedtime. These are 13 days of devotion, companionship, self-sacrifice and love. This trecena points to the eternal conflict that tears at every human being: suspended between two great communions, love and mysticism, each of us strives to survive being swallowed whole by either. On the one hand, the painful shedding of illusions, and on the other, the pleasurable creation of illusions. What ever your decision during this time, you will find favor and advancement. These are good days for commemorating the dead; bad days for clinging to the living.
Harrison Ford was born on day 2-Ozomahtli.
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).
