However, trying to help you, what we can do is to answer in the following general terms about the Maya society.
A common central idea of the articles that have been written about the Maya civilization is that they were great astronomers who liked to observe the stars and possessed a total understanding of the concept of time.
That is why the Mayas built observatories like the one in Chichen Itza, Yucatán, México. This precious building is in good condition and can be visited by tourists.
That is why the Maya society understood the use of time with three important calendars they developed.
The Tzolkin was the divine calendar and consisted of 26 days with 20 months of 13 days.
The Haab was a solar calendar that included 365 days. These days were divided into 18 months of 20 days, and the Uayebm the month with just five days.
The Long Count Calendar was the universal cycle for the Maya civilization and was used to track longer periods.
