When is Xiaoxue?

1, Xiaoxue is the 20th solar term in 24 solar terms and the 2nd solar term in winter. The time is on the 22nd or 23rd of Gregorian calendar 165438+ 10, that is, when the sun reaches 240. Light snow is a solar term reflecting precipitation and temperature, and it is a solar term with high frequency of cold wave and strong cold air activity. The arrival of the light snow solar term means that the weather is getting colder and colder and the precipitation is gradually increasing.

This solar term is called light snow because "snow" is the product of cold weather. During this solar term, the climate is not deep and the precipitation is not heavy, so "light snow" is used to compare the climate characteristics during this solar term. "Light snow" is a metaphor, which reflects the active cold current and increased precipitation in this solar term, rather than the light snow under this solar term.
