Every few years, there are two spring and leap months.

China's calendar has been a kind of lunar calendar since ancient times. It is formulated in combination with the cycles of the sun and the moon. A year is divided into 24 solar terms according to the movement of the sun and several months according to the movement of the moon. The difference between the lunar calendar and the solar calendar is about eleven days. In order to solve the time difference between the lunar calendar and the solar calendar, the ancients added leap months to solve this problem, so that one year in several years is thirteen months, so every 19 years, there are seven years of double spring and seven years of no spring. It can be seen that this is completely an artificial adjustment of solar terms and phenology, and has nothing to do with the auspiciousness of people talking about weddings and funerals.
