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 Calli (House) is governed by Tepeyollotl, Heart of the Mountain, as its provider of tonalli (Shadow Soul) life energy. Calli is a good day for rest, tranquility and family life. Not a good day for participating in public life. Best spent cementing relationships of trust and mutual interests.
The thirteen day period (trecena) that starts with day 1-Cozcacuauhtli (Vulture) is ruled by Xolotl. This trecena signifies the wisdom and freedom of old age; it represents the path of the setting sun. While the way of the warriorpoints to the relationship between predator and prey, this sign points to to the Third Way, which is neither: these are 13 days set aside to perfect the Way of the Scavenger. While the young heart must strategize between offense and defense, the old heart float like the clouds, stooping to earth only to take what no one else wants. These are good days for disengaging; bad days for participating.
