About the Chinese calendar

The traditional Chinese calendar has months that begin at the new moon and inserts a leap month roughly every three years so that the 24 solar terms, each 15 degrees of the Sun's path, stay in their months. The Taichu calendar of 104 BCE fixed the solar terms, and the Shixian calendar of 1645 introduced Western astronomical methods still used today. China adopted the Gregorian calendar in 1912, but the traditional one sets Chinese New Year and other festivals.
