What does the rain solar term mean? Rain is the second solar term.

1. Rain is the second of the 24 solar terms. Every February 19 or so, when the longitude of the sun reaches 330 degrees, it is the rain of 24 solar terms. At this time, the temperature rises, the snow melts and the precipitation increases, hence the name rain. The rain solar term generally starts from February 18 or 19 and ends on March 4 or 5. Rain, like Grain Rain, light snow and heavy snow, is a solar term reflecting precipitation.

2. On February18th every year in Gregorian calendar, it is a rainy solar term, when the sun reaches 330 degrees longitude, which is a "rainy" solar term. Rain has two meanings, one is that the weather gets warmer and the precipitation increases gradually, and the other is that there is less snow and more rain.
