AZTEC CALENDAR Pint Glass

The Aztec calendar actually consists of two different systems: the Tonalpohualli and the Xiuhpohualli. The Tonalpohualli, or "count of days," is a 260-day ritual calendar used for divination and religious ceremonies. The Xiuhpohualli, or "solar year," is a 365-day agricultural calendar used to track the seasons and schedule agricultural activities. The famous Aztec Sun Stone, often mistakenly called the Aztec calendar, primarily represents the Tonalpohualli with its intricate carvings and symbols, showcasing the sophisticated astronomical and mathematical knowledge of the Aztec civilization.
