Is the winter solstice a solar term? What month is it now?

Winter solstice is not a solar term. The winter solstice refers to "Sanjiu", that is, the third nine days from winter to the future, which is about the middle and late period of 1. It's usually the coldest time in winter.

During the winter solstice, although the daytime is the shortest, the ground gets the least solar heat every day, and the daily heat budget deficit of the ground has not reached the maximum. On the solstice after winter, although the day is growing day by day, the growth rate is very slow.

From the winter solstice to the "March 9" period, the average daily growth is only about one minute. The daily heat budget of the ground is still in deficit, so it continues to lose heat and the ground temperature continues to drop. The deficit of total heat balance on the ground only reaches the maximum in the season of March 9. Because the temperature is mainly affected by the ground temperature, this leads to the lowest temperature in the "March 9" season.
