The difference between leap February and February

1, reflecting different times: leap February represents the month after February of the lunar calendar, which occurs every year, but leap February does not occur every year.

2. Different solar terms: leap February appears because the month after February of the lunar calendar only has the solar term "Qingming", and the neutral "Grain Rain" after Qingming falls to the next month, so there will be no neutral atmosphere for one month after February. Therefore, this neutral month after February is named "leap February" after February, which is the significance of the existence of leap February.
