Anotations

Scope note:

Nahua ritual calendar. Literally "count of days." It was made up of twenty periods of thirteen days ("trecenas") which together made up a cycle of two hundred and sixty days. Each day had its own denomination, formed by the combination of a number (from one to thirteen) and twenty different signs.
