Extended data:

Reasons for leap in March:

Divide the year into 24 solar terms, which are inserted in 12 months, and each month has two fixed solar terms: the former is called "festival" and the latter is called "middle". 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".
