The Aztec civilization developed in Mesoamerica beginning in the 1200s. They created a 365-day agricultural calendar and used a sacred calendar as well. They created a writing system that was based on symbols and glyphs. There are Aztec books that remain and that share the rich depictions of Aztec legends. These books also detail the beliefs of the Aztec people and their daily lifestyle.
The Mayan people built their greatest cities between A.D. 250 and A.D. 900. They used two calendars with one being based on a solar year and one on a sacred almanac. The Maya also developed a three-symbol numerical system for recording numbers into the millions.

The Inca civilization is not mentioned in detail here because the civilization failed to come up with a writing system for recording information.
