The significance of this day
Day Cuetzpalin (Lizard), known as Kan in Maya is governed by Huehuecoyotl, the Trickster, as its provider of tonalli (Shadow Soul) life energy. Cuetzpallin signifies rapid reversals of fortune. It is a good day to work on your reputation through actions, not words.
The thirteen day period (trecena) that starts with day 1-Calli (House) is ruled by Itzpapalotl. The 13 days of this trecena are governed by the conflict between culture and nature: the native desire of human beings to maintain a lineage of customs and beliefs is periodically disrupted by the evolutionary leaps of nature. In this sense, nature is represented as the house into which we are born and culture as the house into which we move. These are 13 days of struggling to decide which house is really home. With every step forward, the warrior still stands at the center of the crossroads: the heart must be trained if it is to be a reliable compass. These are good days to focus on the future; bad days to focus on the past.
Vanessa L. Williams was born on day 2-Cuetzpalin.
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.
