The significance of this day
Aztec facts
In the Mayan Long Count, the 13th b'ak'tun (144.000 day cycle) started on the winter solstice of 2012 (December 21, 2012).
4-Acatl is the calendric sign of Xiuhtecuhtli, Lord of the Year, the God of Fire.
This is the last of the five unlucky days (nemontemi) at the end of a year (xihuitl). It is better not to carry out any activity during these unfortunate and useless days. These nemontemi are extra dangerous because they are at the end of a calendar round of 52 years (xiuhmolpilli or bundle). All fires are to be extinguished. No public events are organized. After the nemontemi, there are seven days to prepare for the New Fire ceremony, held before the start of the day 1-Cipactli, the first day of the new bundle of years.
Day Acatl (Reed) 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-Itzcuintli (Dog) is ruled by Xipe Totec, Lord of Shedding, god of seedtime. These are 13 days of devotion, companionship, self-sacrifice and love. This trecena points to the eternal conflict that tears at every human being: suspended between two great communions, love and mysticism, each of us strives to survive being swallowed whole by either. On the one hand, the painful shedding of illusions, and on the other, the pleasurable creation of illusions. What ever your decision during this time, you will find favor and advancement. These are good days for commemorating the dead; bad days for clinging to the living.
