The Aztec Calendar
On the timeline · around Aztec period ·
What happened
The Aztecs kept two interlocking calendars: a 260-day sacred cycle (tonalpohualli) and a 365-day solar year (xiuhpohualli). Together they meshed into a 52-year 'Calendar Round,' whose completion was marked by the great New Fire Ceremony to renew the world.
Why it matters
The calendar governed Aztec ritual, farming and fate. The dread that the world might end every 52 years — and the fire ceremony that renewed it — lay at the heart of their religion.
