DESCRIPTION

Date::Calendar::Aztec::Cortes is a class that implements the Aztec calendars (tonalpohualli and xiuhpohualli).

This class uses Francisco Cortes the correlation. Another class uses the Alfonso Caso correlation, see Date::Calendar::Aztec.

Aztecs used two different calendars, the civil calendar or "xiuhpohualli" and the clerical calendar or "tonalpohualli".

The civil calendar is organized like other calendars, with days grouped in months grouped in years. The difference with other calendars is that the months last 20 days each, not around 30, and there are 18 months, not 12. In addition, there are 5 additional days (Nemontemi), but no leap days are defined.

A last difference with other calendars is that years are not numbered.

The clerical calendar consists of two simultaneous cycles, the first one with numbers 1 to 13, the second one with 20 names. This gives a clerical year of 260 days.

See the documentation in the other Aztec calendar class, Date::Calendar::Aztec.
