The celestial cycles allowed the Aztecs to track the length of the photo voltaic 12 months, lunar month, and the revolution of Venus (found to be 584 days). The discoveries they made enabled for the calibration of calendars and signalling of special ceremonial days.

The Aztec yr consisted of 18 months of 20 days each, counting the circle clock-sensible 18 consecutive times, with a specific title for every month.
