Is it the season of increasing autumn rain?

The increase of rain is in the spring solar term, not in autumn. Among the 24 solar terms in China, rain is the second solar term in spring, which occurs between February 18 and 20 on the Gregorian calendar. The solar term of rain marks the arrival of spring, with warmer weather, melting ice and snow, moist air and increasing rainfall. In the autumn solar terms, the vernal equinox solar terms are related to rain. The autumnal equinox solar terms indicate the beginning of autumn and appear on September 22 or 23 of the Gregorian calendar. At this time, the weather is getting colder and the time of day and night is equal.
