The significance of this day
Aztec facts
La Malinche, or Doña Marina, was an Aztec woman who became an essential partner for Hernán Cortés in his conquest of the Aztec empire. Doña Marina's Aztec name was Malinalli, after her birthday. Cleary, she acted upon the significance of this day.
This is the first of the five unlucky days (nemontemi) at the end of a year (xihuitl). It is better not to carry out any activity during these unfortunate and useless days.
Day Quiahuitl (Rain) is governed by Tonatiuh, the Sun God, as its provider of tonalli (Shadow Soul) life energy. Quiahuitl is a day of relying on the unpredictable fortunes of fate. It is a good day for traveling and learning, a bad day for business and planning.
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.
