What role did astronomy play in Maya civilization?

In Maya civilization, astronomy was a highly sophisticated intellectual pursuit that was inextricably linked to their religion and calendrical systems. Maya astronomers achieved remarkable precision in their observations, which served several critical functions:1

• Timekeeping and Chronology: Astronomy underlay the complex Maya calendar, which included the 260-day Tzolkin (sacred ritual cycle) and the 365-day solar year. These systems allowed the Maya to track time across vast periods, including the Long Count, a continuous marking of time from a base date in 3114 BCE.2134
• Predictive Science: Maya scholars compiled precise tables tracking the positions of the Moon and the planet Venus. They were also able to calculate the duration of the solar year with great accuracy and developed methods to predict solar eclipses.12
• Religious and Cultural Integration: Astronomy was not a secular science but a sacred one. Priests used these observations to conduct elaborate rituals and ceremonies, as the Maya believed that celestial movements and the passage of time were deeply connected to the divine and the fate of their society.21

While some scholars have hypothesized that certain architectural structures served as observatories for solstices and equinoxes, these claims remain difficult to substantiate.3
