Astronomy, Architecture and the Calendar

Mayan buildings were often laid out in accordance with astronomy. Temples and pyramids were designed so that the sun, moon, stars, and planets would be visible from the top or through specific windows at certain times of the year.

The Mayan calendar was associated with astronomy. The Maya used two calendars: The Long Count calendar was divided into a solar year as a base, and the Calendar Round consisted of two calendars - a 365-day solar year and a 260-day Tzolkin cycle.
