How is the Aztec calendar different from the modern calendar?
The Aztec calendar is different from the modern calendar in many
ways. Many have seen the iconic image of the circular Aztec
calendar; this illustrates that the Aztecs viewed time as cyclical
rather than linear. The Aztec calendar is also made up of two
systems that can work independently or coherently. Mythology is
also deeply integrated into the Aztec calendar, incorporating the
all-important equilibrium of the spiritual and natural world.
