The significance of this day
Aztec facts
The Aztec, Maya and most other mesoamerican people used the same 260-day calendar with an identical correlation. So the Aztec date 1-Cipactli corresponds to 1-Imix for the Maya, etcetera.
Day Atl (Water) is governed by Xiuhtecuhtli, God of Fire, as its provider of tonalli (Shadow Soul) life energy. Atl is a day for purification by subjecting oneself to the ordeal of conflict. It is a good day for battle, a bad day for rest. Water brings out the scorpion, who must sting its enemies or else sting itself. Atl is the day of the holy war, which is always a battle with one's own enemies within.
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.
