The significance of this day
Aztec facts
The Aztecs did not use a leap year correction but they knew the length of a solar year is neither 365 nor 365.25 days. Presumably they kept some count of days to register astronomical events but no evidence of an Aztec Long Count exists.
Day Cuauhtli (Eagle) is governed by Xipe Totec, God of Seedtime, as its provider of tonalli (Shadow Soul) life energy. Cuauhtli is a day of fighting for freedom and equality. It is a day of the Warriors of Huitzilopochtli, those who sacrifice their lives willingly to keep the present age, the Fifth Sol, moving. It is a good day for action, a bad day for reflection. A good day for invoking the gods, a bad day for ignoring them.
The thirteen day period (trecena) that starts with day 1-Miquiztli (Death) is ruled by Tonatiuh. This trecena signifies the vast cosmological forces at play in the lives of human beings. These 13 days are all influenced by transformative powers of unknown dimension, origin and intent. The days of this trecena often pass by unnoticed since they are not remarkable until the elementals turn their attention to this place, the first of the thirteen skies; when this occurs, though, the whole of the world changes. It is during these days that the song of the Old Ones may best be heard. These are good days to fulfill old obligations; bad days to go back on one's word.
