The significance of this day
Aztec facts
In the Mayan Long Count, the 13th b'ak'tun (144.000 day cycle) started on the winter solstice of 2012 (December 21, 2012).
4-Ocelotl is is the fourth day of eight days in a row specially associated with pulque, the alcoholic beverage made from the fermented sap of the maguey (agave) plant (octli).
Day Ocelotl (Jaguar) is governed by Tlazolteotl as its provider of tonalli (Shadow Soul) life energy. Ocelotl is a good day for doing battle. It signifies power, valor, and reckless abandon in the face of danger. This is a day of the Warriors of Tezcatlipoca, those who willingly sacrifice their lives to keep the flame of the Old Ones burning forever.
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.
