The significance of this day
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).
This is the fourth 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 Malinalli (Grass) is governed by Patecatl as its provider of tonalli (Shadow Soul) life energy. This day signifies tenacity, rejuvenation, that which cannot be uprooted forever. Malinalli is a day for persevering against all odds and for creating alliances that will survive the test of time. It is a good day for those who are suppressed, a bad day for their suppressors.
The thirteen day period (trecena) that starts with day 1-Atl (Water) is ruled by Chalchihuihtotolin. These are 13 days of instability and unexpected events, of accidents and coincidences: these are good days to gamble a little on a long-shot; bad days to gamble a lot on a sure thing. Every day rollercoasters between all-good and all-bad, between rapture and terror. This trecena advises the priest-warrior to perfect the art of shapeshifting: only by mimicking the nature of water do we become an agent of change rather than a target of it. The purified heart casts no reflection in the smoking mirror.
Howard Stern was born on day 4-Malinalli.
