The significance of this day
Day Xochitl (Flower) is governed by Xochiquetzal, Flower Feather, as its provider of tonalli (Shadow Soul) life energy. Xochitl is a day for creating beauty and truth, especially that which speaks to the heart who knows it will one day cease to beat. Xochitl reminds us that life, like the flower, is beautiful but quickly fades. It is a good day for reflection, companionship and poignancy; it is a bad day for repressing deep-seated wishes, desires and passions.
The thirteen day period (trecena) that starts with day 1-Ollin (Movement) is ruled by Tlazolteotl. This trecena is governed by the goddess of cotton and weaving, of sexuality and childbirth, she who is the eater of sins: it is the sign of the Scavenger, who feeds not on power but on the ills that darken the heart. The rainbow serpent, symbol of pleasure and folly, levitates amidst a shroud of smoke and shadow: these are 13 days of stolen secrets and odd twists of fate. The earth itself shakes: the ills created by shock can sometimes only be cured by greater shock. These are good days for self-purification; bad days for self-gratification.
Sandra Bullock was born on day 4-Xochitl.
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).
