The Aztec Calendar: Aligning Sacrifice with Celestial Events

I. Introduction to the Aztec Calendar

The Aztec calendar is a remarkable system that reflects the complexities of Aztec culture and religion. It serves not only as a measure of time but also as a vital tool for aligning human activities, particularly ritual sacrifices, with the cosmic order.

The Aztecs utilized a dual calendar system comprised of two primary calendars: the Tonalpohualli and the Xiuhpohualli. Each played a significant role in their societal structure, guiding everything from agricultural practices to religious ceremonies.

Celestial events were of utmost importance in Aztec society, as they believed these occurrences were manifestations of divine will, influencing their lives and spiritual practices.
