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 Malinalli (Grass) is governed by Patecatl as its provider of tonalli (Shadow Soul) life energy. This day signifies tenacity, rejuvenation, that which cannot be uprooted forever. Malinalli is a day for persevering against all odds and for creating alliances that will survive the test of time. It is a good day for those who are suppressed, a bad day for their suppressors.
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.
