The significance of this day
Aztec facts
Aztecs named a newborn child after its day (tonalli) of birth. The elemental forces ruling over that day strongly characterize a person and its destiny.
Day Itzcuintli (Dog) is governed by Mictlantecuhtli, God of Death, as its provider of tonalli (Shadow Soul) life energy. Itzcuintli is the guide for the dead, the spirit world's link with the living. Itzcuintli is a good day for funerals and wakes and remembering the dead. It is a good day for being trustworthy, a bad day for trusting others of questionable intent.
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.
