Module 6 of 6

Working the Calendar: Practice and Ceremony Today

Putting the system to use — reading a date in full, tracking the year through its veintenas, keeping the new year, and treating the auguries as historical testimony rather than prescription.

Lecture

What to take from this module

  • A complete date names the day of the tonalpowalli, the position in the veintena, and the year bearer.
  • Keeping the count is a daily practice: the count only stays alive if someone counts it.
  • The auguries of Book 4 of the Florentine Codex record how day keepers read the days; read them as testimony from a place and time.
  • The observed equinox sunrise ties off the old year; the new year begins the day after — the moment the whole system is re-anchored.
