Important solar terms in the twenty-four solar terms:

The four most important solar terms in the twenty-four solar terms are vernal equinox, summer solstice, autumn equinox and winter solstice, which are collectively called "one divides into two". The most critical nodes are the winter solstice and the summer solstice, which is the time when the natural climate appears "from yin to yang", and the winter solstice is the first day of September 19. After the winter solstice, the yang gradually grows, the yin gradually decreases, the days get longer and the nights get shorter.

During the Spring and Autumn Period, the ancients observed the sun with the earth, and determined that the winter solstice was between 65438+February 2 1 to 23 in the solar calendar every year. The Zhou Dynasty started from the winter solstice, with the shortest day and the longest night, so it was considered as the beginning of a new year.

The winter solstice is the cloudy peak, that is, the cold peak. Cold dominates the harvest, and all life activities in nature turn from prosperity to decline and from dynamic to static in the cold season.
