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 Miquiztli (Death) is governed by Tecciztecatl, the Moon God, as its provider of tonalli (Shadow Soul) life energy. It is a good day for reflecting on your priorities in life, a bad day for ignoring possibilities. It is a day of transformation, signifying that briefest moment between old endings and new beginnings.
The thirteen day period (trecena) that starts with day 1-Ehecatl (Wind) is ruled by Chantico. The 13 days of this trecena are governed by the elemental intent of the divine Whirlwind: to create chaos out of order. Order and reason outlive their purpose and must be replaced by the potential for new, unexpected, unpredictable, change. It is precisely in the heart of order that the lightningbolt strikes. These are 13 days of instability and insecurity. The warrior prefers to have no relationships if the only alternative is to have bad relationships: thievery abounds and no treasure of the heart is safe. These are good days to be in the vanguard; bad days to be encamped behind the front.
