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 Acatl (Reed) is governed by Tezcatlipoca as its provider of tonalli (Shadow Soul) life energy. Acatl is the scepter of authority which is, paradoxically, hollow. It is a day when the arrows of fate fall from the sky like lightningbolts. A good day to seek justice, a bad day to act against others.
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.
