Extended data:

"Leap year", which we usually say is 365 days a year, is actually a rough figure, and the exact figure should be 365.2422 days. Then there are 365 days in a year, which is 0.2422 days different from the actual year, so four years later, it is nearly one day less than the actual year. In order to make up for this difference, the calendar stipulates that four years is a leap year, that is, a year divisible by four is a leap year. In addition, it is stipulated that every century year (the year with two zeros at the end) must be divisible by 400 to be a leap year, and other hundred years are not leap years, that is, "there is no leap in a hundred years". For example, 1996 is a leap year, and 2000 is also a leap year, but 1700 is not.

The leap year in the solar calendar has 29 days in February, the leap day is February 29 and the leap year in the solar calendar has 366 days. That is to say, February of leap year in the solar calendar is not called leap February, and leap month is unique to the lunar calendar.
