Step-by-step explanation:
The development of the Aztec culture influenced the development of the calendar through their advanced understanding of astronomy. The Aztecs, like other Mesoamerican cultures, developed accurate and complex calendar systems based on astronomical observations. They used a 260-day sacred calendar and a 365-day agricultural calendar.
These calendars were essential for organizing religious ceremonies, agricultural activities, and societal events. The Aztecs' belief in the power of their gods, which controlled the fate of each day in the calendar, influenced their rituals and the importance they placed on the calendar. The influence of the Aztec culture can be seen in the organization and structure of the calendar systems used by Mesoamerican civilizations.
