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 Mazatl (Deer) is governed by Tlaloc, God of Rain and Thunderstorms, as its provider of tonalli (Shadow Soul) life energy. Mazatl is the day of the hunt. It is a good day to stalk your quarry, a bad day to be stalked. Mazatl is a day for breaking old routines and to pay close attention to the routines of others. This is a day for doubling-back on your tracks.
The thirteen day period (trecena) that starts with day 1-Quiahuitl (Rain) is ruled by Tlaloc, He Who Makes Things Sprout, god of rain, lightning and thunder. This trecena represents a time of alternating drought and flood. There is either not enough or too much. It is a time of hardship and suffering. The rainmaker stands alone atop the mountain, holding firesticks and a medicine bundle: help will be offered but may not be accepted. Some will have prepared for this time but not enough to care for everyone in need. These are good days to pursue solitude and learning; bad days to count on others.
