USA HISTORY

Detailed explanation-1: -The Aztec solar year contained 18 months of 20 days each, with 5 extra days. Time was divided into “centuries” of 52 years. The calendar represents the Aztec belief that the universe had already passed through four world creations, which had all been destroyed.

Detailed explanation-2: -Long known for their cool circular calendars and practice of human sacrifice, Aztecs were also math whizzes. Aztecs used hand, heart and arrow symbols to represent fractional distances when calculating areas of land, scientists have discovered.

Detailed explanation-3: -Just like the Chinese and western astrology, Aztecs also believed that the stars and constellations defined a person’s character traits and fortune. For the star signs, they used the shorter calendar of 260 days. Each zodiac sign lasted 13 days, so there were 20 signs.

Detailed explanation-4: -The Aztecs used a complex calendar system characteristic of Mesoamerican civilisations. It combined a count of 365 days based on the solar year with a separate calendar of 260 days based on various rituals. Every 52 years, both calendars would overlap and a new cycle would commence.
