What March has a leap year! ?

2031(191year), 2050 (Geng Wunian), 206 1 (Xin Sinian), and 2080 (Gengzi Year).

Leap March is two March in the lunar calendar year, and the second March is leap March. It is because the appearance of the sun and the moon is not caused by the number of whole days for the rotation period of the earth.

Leap March is a leap month with moderate frequency, sometimes once every 19 years (such as 1936 and 1955), sometimes once every 8 years (such as 2786 and 2794) or once every1year.

The date of the Spring Festival in March is generally second only to the earliest year of the Spring Festival, and a few of the earliest years of the Spring Festival leap in March.

Extended data

Through long-term practice, our ancestors divided a year into 24 solar terms, which were placed in 12 months, and each month had two fixed solar terms: the former was called "Festival" and the latter was called "Zhong". Such as "beginning of spring" and "Rain" in the first month. The former is "frugality" and the latter is "moderation".

Solar terms and neutral gas are alternately arranged in monthly order. The average interval between two adjacent solar terms and neutral gas is 30 and a half days. However, the average lunar month (the first lunar month) is only 29 and a half days. In this way, next month's solar terms or gas will be delayed by one or two days from the previous month's solar terms and gas. At a certain point in time, "Zhong Qi" was not in the middle of the month and then moved to the end of the month.

Next month, there will be only one kind of "frugality" and no "moderation". According to the lunar calendar, any month with only solar terms and no neutral atmosphere can not be regarded as a month independently, but only as a subsidiary (sub-month) of a month-leap month.

Leap March occurs when the month after March has only solar terms, and the neutral gas after solar terms falls to another month, so there will be a month without neutral gas after March, so the month without neutral gas after March is named "leap March", which is the reason for leap March.
