The Chinese lunar calendar, also known as the lunisolar calendar, is a traditional calendar used in China and other East Asian countries. It is based on the cycles of the moon and the sun, and it is used to determine dates for festivals, holidays, and other important events.
The Chinese lunar calendar is a complex system that has been used for centuries. It is based on a 12-year cycle, with each year being named after an animal of the Chinese zodiac. The calendar also includes a 24-hour cycle, with each day being divided into 12 two-hour periods. This uses the concept of a (Ganzhi), which pairs the 10 Heavenly Stems with the 12 Earthly Branches to create 60 unique combinations.
