The significance of this day
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-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.
Britney Spears was born on day 10-Acatl.
Aztec facts
In the years after the conquest of Mexico, the xiuhpohualli (solar calendar) became tied to the Julian calendar as used by the Spaniards. This effectively introduced a leap year to the Aztec calendar every four years (this site provides the pre-conquest calendar).
