The Aztec Calendar: A Journey Through the Sacred and Profane

I. Introduction to the Aztec Calendar

The Aztec calendar is a complex and fascinating system that played a crucial role in the lives of the Aztec people. It served not just as a way to track time, but as a framework for understanding the cosmos and the cycles of life. The calendar was deeply intertwined with religious beliefs, agricultural practices, and social organization, reflecting both the sacred and profane aspects of Aztec culture.

This article aims to explore the intricate layers of the Aztec calendar, shedding light on its two main cycles, the Tonalpohualli and the Xiuhpohualli, and how these cycles influenced the everyday lives of the Aztecs.

II. The Structure of the Aztec Calendar

The Aztec calendar consists of two primary cycles that work in tandem to create a comprehensive system of timekeeping:

• Tonalpohualli: The sacred calendar, consisting of 260 days.
• Xiuhpohualli: The solar calendar, comprising 365 days.

A. Explanation of the two main cycles: Tonalpohualli and Xiuhpohualli

The integration of these two cycles allowed the Aztecs to keep track of both sacred and secular time. The Tonalpohualli, or the divine calendar, was used primarily for religious purposes, while the Xiuhpohualli was aligned with the agricultural year and seasonal changes.

The Tonalpohualli consists of 20 day signs combined with 13 numbers, creating a 260-day cycle that was vital for divination and ritual practices. The Xiuhpohualli, on the other hand, is a 365-day solar calendar divided into 18 months of 20 days each, plus an additional month of 5 “empty” days, known as ‘nemontemi’.

Throughout the year, the Xiuhpohualli featured numerous festivals, each with its own rituals and significance. Some key festivals included:
