AZTEC CALENDAR Whiskey Glass

The Aztec calendar is known for its complexity and accuracy, featuring two main cycles that interlock: the 260-day sacred calendar called the Tonalpohualli and the 365-day solar calendar known as the Xiuhpohualli. The Tonalpohualli was used primarily for divinatory purposes, guiding the Aztecs in matters of spirituality and ritual, while the Xiuhpohualli governed the agricultural and civic year, including the timing of festivals. These calendars were so precise that they played a central role in the daily and ceremonial life of the Aztec civilization, reflecting their sophisticated understanding of time and astronomy.
