This calendar is part of an ongoing project by Yankwik Mexikayotl to introduce traditional Mesoamerican time keeping to the general public. This website provides an in-depth look at the calendar system, the monthly ceremonies, and the methods used to arrive at our correlation. The central Mexican calendar is a living system for tracking the movement of the sun. We hope that by equipping individuals with the tools needed to not just use, but also actually understand this calendar, we help ensure its survival for generations to come. The count presented in this calendar is based on research provided by Ruben Ochoa.
