The significance of this day
Aztec facts
The Aztec, Maya and most other mesoamerican people used the same 260-day calendar with an identical correlation. So the Aztec date 1-Cipactli corresponds to 1-Imix for the Maya, etcetera.
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-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.
