The significance of this day
Day Tecpatl (Stone Knife, known as Etznab in Maya) is governed by Chalchihuihtotolin, the Jewelled Fowl, as its provider of tonalli (Shadow Soul) life energy. Tecpatl is a day of grave ordeals, a day of trials and tribulations. It is a good day to test one's character, a bad day to rest on one's past accomplishments or reputation. Tecpatl warns that the mind, the spirit, must be sharpened like the glass blade which cuts to the marrow of truth
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.
Tim Burton was born on day 13-Tecpatl.
Aztec facts
In the years after the conquest of Mexico, the xiuhpohualli (solar calendar) became tied to the Julian calendar as used by the Spaniards. This effectively introduced a leap year to the Aztec calendar every four years (this site provides the pre-conquest calendar).
