Chinese Leap Year has a leap month

While the Gregorian calendar adds only one leap day (February 29) nearly every four years, a whole leap month is added to the Chinese calendar every 3 years.

The name of a leap month is the same as the previous lunar month. The leap month’s place in the Chinese calendar varies from year to year. Unlike in the Gregorian calendar, 2015 is a leap year in the Chinese calendar.

How is the leap month calculated?

To determine a leap year, calculate the number of new moons between the 11th month in one year and the 11th month in the following year.

A leap month is inserted if there are 13 moons from the start of the 11th month in the first year to the start of the 11th month in the next year. The leap month does not contain a principal term (Zhongqi).

The Chinese calendar has been used for centuries and observes the movement of the Sun, Moon and stars.
