The 20 Day Signs of the Aztec Calendar: A Detailed Exploration

I. Introduction to the Aztec Calendar

The Aztec calendar is a complex system that reflects the intricate relationship between time, spirituality, and the natural world. Part of the broader Mesoamerican calendar system, it played a pivotal role in the lives of the Aztec people. The calendar was not merely a tool for tracking days; it was a fundamental aspect of Aztec culture, influencing their rituals, agricultural practices, and societal organization.

Central to this calendar are the 20 day signs, each symbolizing different aspects of life and the cosmos. These signs are deeply woven into the fabric of Aztec mythology and beliefs, serving as a guide for personal identity, destiny, and the natural cycles of the world.

II. The Structure of the Aztec Calendar

The Aztec calendar comprises two main cycles: the Tonalpohualli, a 260-day cycle, and the Xiuhpohualli, a 365-day solar calendar. The Tonalpohualli is particularly significant as it combines the 20 day signs with a series of 13 numbers, creating a unique system of days that repeats every 260 days. This combination produces 260 distinct day combinations, each carrying specific meanings and attributes.

The relationship between the day signs and the numbers is crucial, as each day sign is associated with a specific energy, influenced by the number it corresponds to. This interplay of signs and numbers establishes a deep connection between the celestial and terrestrial realms, guiding daily life and spiritual practices.
