The significance of this day
Day Cuauhtli (Eagle, known as Men in Maya) is governed by Xipe Totec, God of Seedtime, as its provider of tonalli (Shadow Soul) life energy. Cuauhtli is a day of fighting for freedom and equality. It is a day of the Warriors of Huitzilopochtli, those who sacrifice their lives willingly to keep the present age, the Fifth Sol, moving. It is a good day for action, a bad day for reflection. A good day for invoking the gods, a bad day for ignoring them.
The thirteen day period (trecena) that starts with day 1-Cuetzpalin (Lizard) is ruled by Itzlacoliuhqui. The 13 days of this trecena are governed by the meting out of irrational rewards and punishments. These are 13 days of confusion, a time when the noble and ignoble have equal chance to be raised up or thrown down. The warrior must be like the lizard, who is not hurt from a high fall but, instead, immediately climbs back to its perch. These are good days to keep out of sight; bad days to attract attention.

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.
