农历, or the Lunar Calendar, is a calendar system based on the phases of the moon. It is widely used in many Asian cultures, including 中国 (China), to determine traditional festivals and agricultural activities. The calendar typically consists of 12 months, with each month beginning on the new moon. The 农历 is important for celebrating various cultural events, such as the 春节 (Spring Festival) and the 中秋节 (Mid-Autumn Festival). Unlike the Gregorian calendar, which is solar-based, the lunar calendar helps people track seasonal changes and plan farming activities according to lunar cycles.
