how many days was in the mayan calendar?
Early Mayan astronomers used the 260 day calendar to record the movements of the planets, sun and moon: it was a very sacred calendar. When used consecutively with the standard 365 day haab calendar, the two would align every 52 years. The Maya Long Count Calendar: The Maya developed another calendar, better suited for measuring longer periods of time. The Maya Long Count used only the haab or 365 day calendar. A date was given in terms of Baktuns (periods of 400 years) followed by Katuns (periods of 20 years) followed by Tuns (years) followed by Uinals (periods of 20 days) and ending with the Kins (number of days 1-19).
