Like other Mesoamerican civilizations, the Maya used a numbering system to base 20 (vigesimal) and base 5. Also the Preclassic Maya (or their Olmec predecessors) independently developed the concept of zero around the year 36 BC.

Produced extremely accurate astronomical observations, their diagrams movements of the moon and planets are equal or superior to those of any other civilization working eye. Also, like other Mesoamerican civilizations, the Maya discovered an accurate measure of the length of the solar year, far more accurate than that used in Europe with the Gregorian calendar.
