What is the Lunar Calendar?
The Chinese lunar calendar, with over 4,000 years of history, is based on the cycles of the moon and is typically 11 to 12 days shorter than the solar year. It is particularly accurate in calculating agricultural sowing, harvesting, and seasonal changes.
What is the Gregorian Calendar?
The Gregorian calendar is the calendar currently used by most of the world. It was introduced by Pope Gregory XIII in 1582 to replace the Julian Calendar, with improved accuracy in aligning with the solar year.
