The Maya are known for their contributions to mathematics, astronomy, and the development of which system?

• A. 100-350 CE
• B. 300-900 CE
• C. 900-1200 CE
• D. 1200-1500 CE

Answer: (B)

The Maya calendar and their astronomical math flourished most fully during the Classic Maya period, roughly 300–900 CE. This era is when inscriptions, monuments, and city-states show a sophisticated calendrical system built from a 260-day ritual cycle and a 365-day solar year, later integrated into a broader Calendar Round and the Long Count for long-range dating. That development and documentation of their calendar and astronomical knowledge are what the question is pointing to, making this timeframe the best fit. Earlier or later periods don’t—at the same scale—display the same mature calendar system in the archaeological record.
