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 Ehecatl (Wind) is governed by Quetzalcoatl as its provider of tonalli (Shadow Soul) life energy. Ehecatl is a bad day for working with others. Its influences are inconstant and vain. A good day to root out bad habits.
The thirteen day period (trecena) that starts with day 1-Ozomahtli (Monkey) is ruled by Patecatl. The 13 days of this trecena are influenced by the quest for cures of all the various ills that befall us: the quest to obtain power that can overcome misfortune lies at the heart of the warrior's purpose. The transformation of poison into medicine, and evil into good, is an art whose expression must be tailored to the field of battle. These are good days to fashion a war shield and collect articles for your medicine bundle; bad days to allow infections to fester.
