Are beginning of winter and the winter solstice solar terms?

Beginning of winter and the winter solstice are not a solar term.

The soul of the sun rises in winter, which is the beginning of the traditional calendar. Every year around 65438+February 22nd, the sun rotates 270 degrees around the yellow meridian. After the winter solstice solar term, the sun shadow is the longest. On this day, the northern hemisphere has the shortest half-day and the longest night, and it began to enter the cold weather.
