This app puts the Mayan Dreamspell Calendar in your pocket! "13:20:Sync makes it so much easier to understand and integrate the calendar into every day life. Highly recommend it."

Following these cycles can help you get a stronger connection with nature around you and become conscious of your essence. This app provides a simple way to sync along those cycles, to raise our frequency and give us a new lens to view both our day-to-day and planetary events. - Did you ever realize that our (Gregorian) calendar is not a harmonic calendar? - Did you know that the moon has 13 (not 12!) orbits around the earth in 1 year? - Why do we live with this irregular calendar? - Are you interested in Astrology? -> All this, and more, is explained carefully in this app. (over 15.000 words on 37 pages) Please note that these text are in English language only.
