How many years is February?

The frequency of leap February is second only to leap March, and the frequency of leap February is moderate around 2 1 century, generally once every 19 years (such as 2004 and 2023). Since then, the frequency of leap February has gradually decreased, becoming a rare leap month, which occurs once every century from 25th to 28th century, and there is no leap February in 29th to 30th century, 36th to 38th century and 40th to 44th century.

In order to make the seasons of the lunar calendar and the solar calendar coincide, the ancestors used the method of "adding leap months" to "adjust the surplus and deficiency" and set up seven leap months in 19, because the total number of days in the tropical year of 19 is basically equal to the total number of days in the normal year plus seven leap months. So the lunar calendar stipulates a leap month every two or three years.

Leap February appears because the month after February of the lunar calendar only has clear solar terms, and the neutral Grain Rain falls in the next month after Qingming, so there will be a month after February without neutrality. Therefore, there is no neutral month after February and it is named "leap February" after February, which is the origin of leap February.

3, two spring and one winter, ten cowsheds and nine empty.

Two spring and one winter refers to two beginning of spring solar terms separated by a winter. Ten cowpens and nine empty pens mean that the number of cows will be greatly reduced.
