Mayans had many breakthroughs in astronomy and mathematics. Priest studied the sky with observatories. They were able to track the movement of stars and planets with great accuracy. The Mayans used their observations to calculate the solar year. The Mayan figure for their year of 365.2420 days is amazingly precise.These calculations allowed the Mayas to create their solar calendar of 365 days. They also had a sacred 260-day calendar. Every 52 years, the first date in both calendars fell on the same day. This gave the Mayas a longer unit of time that they called a Calendar Round. For the ancient Mayas, this 52-year period was something like what a century is to us.
The Mayas also recognized the need for zero.
