The maya developed two different calendars for which two aspects of their lives?

The Mayans developed these calendars, on the one hand to govern the time of their agricultural work because it allowed them to see the annual cycles of the sun, carrying out rituals to ask for rain and make offerings during the cycle of growth of corn, especially during sowing and harvesting. They were also used to know when to plant, when the rains came, when to prepare the land, among other things.

On the other hand these types of calendar allowed them to start and end religious festivities (each day was assigned a supernatural being of the Mayan religion, which assigned the character and destiny of a man according to the date he was born) and allowed measure the age of people, lunar cycles and eclipses. It also served to determinate the pattern of ritual life and provides the basis for making prophecies.
