Quizplus · Accepted Answer

The Maya civilization developed a highly accurate and complex calendar system, known as the Long Count calendar, which was based on astronomical observations and allowed them to accurately predict celestial events and track time over long periods of time. The Aztecs and the Olmecs also had calendar systems, but they were not as accurate or advanced as the Maya's. The Nazca civilization, on the other hand, did not have a calendar system.
