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 Ollin (Movement) is governed by Xolotl as its provider of tonalli (Shadow Soul) life energy. This is an auspicious day for the active principle, a bad day for the passive principle. Ollin is a day of the purified heart, signifying those moments where human beings may perceive what they are becoming. A good day for transmutation, which arrives like an earthquake that leaves in its wake the ruins of rationality, order and the preconceived.
The thirteen day period (trecena) that starts with day 1-Atl (Water) is ruled by Chalchihuihtotolin. These are 13 days of instability and unexpected events, of accidents and coincidences: these are good days to gamble a little on a long-shot; bad days to gamble a lot on a sure thing. Every day rollercoasters between all-good and all-bad, between rapture and terror. This trecena advises the priest-warrior to perfect the art of shapeshifting: only by mimicking the nature of water do we become an agent of change rather than a target of it. The purified heart casts no reflection in the smoking mirror.
