observations of solar eclipses from many different cultures and civilizations
date back to at least 2500 BC in the writings that have survived from
ancient China and Babylon. To establish an accurate luni-solar calendar,
people in ancient civilizations observed the moon regularly. Lunar
eclipses were the first major celestial events that astrologers learned
how to predict based on local historical observation records.
