The significance of this day
1-Acatl is the name day of Quetzalcoatl.
Day Acatl (Reed, known as Ben in Maya) is governed by Tezcatlipoca as its provider of tonalli (Shadow Soul) life energy. Acatl is the scepter of authority which is, paradoxically, hollow. It is a day when the arrows of fate fall from the sky like lightningbolts. A good day to seek justice, a bad day to act against others.
The thirteen day period (trecena) that starts with day 1-Acatl (Reed) is ruled by Chalchihuitlicue, goddess of lakes, rivers and seas, goddess of horizontal waters. This trecena signifies the transitory nature of all that we may gain in life: it is a reminder to view success and failure, gain and loss, as matters of fate and not as matters of personal worth. The elementals do not reward nor punishment our efforts but, rather, construct the maze within which we might perfect our hearts. The 13 days of this trecena reveal our hearts to us, based on whether we have decided to live within the house of shadows or to seek the secret of happiness elsewhere. These are good days to travel to new places; bad days to hide in fear.
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.
