Other solar terms have changed again. Why is the light snow unchanged?

I'm glad to answer your question. The change of the 24 solar terms is not very big, generally the difference is at most one or two days.

The spring rain shakes the spring and clears the valley, and the summer is full of mountains and summers. Autumn dew, autumn frost, little snow in winter and cold in winter. The two festivals remain unchanged every month, with a maximum difference of one or two days. The first half of the year is June 2 1 day, and the second half is August 23.

(The first half of the year is around the 6th of each month, 2 1, and the second half is around the 8th of each month.) Very accurate. I hope my answer can help you.
