Alternating Time of Yin and Yang in Solstice Winter

In 2023, the alternation time of Yin and Yang from winter to sun is 65438+February 22nd 1 1:27:09.

Winter solstice is a solar term divided by astronomy, which was called "short day" and "short day" in ancient times. From winter to the sun, the sun is located at 270 degrees of the Yellow Meridian, and the sun shines almost directly to the Tropic of Capricorn, which has the shortest day in the northern hemisphere. It takes about 10 hours from sunrise to sunset. From winter to the future, as the earth orbits the sun, the direct sunlight belt gradually moves northward, making the days in the northern hemisphere gradually longer and the nights gradually shorter.

In winter solstice, although the height of the sun is the lowest, the sunshine time is the shortest, and the heat absorbed by the ground is less than the heat lost, the heat accumulated on the ground for a long time continues to be lost, and the temperature near the ground layer has not dropped to the lowest, so it is not the coldest time of the year.

After the winter solstice, although the days are getting longer and shorter, the days are getting shorter and shorter, and the nights are getting longer and longer in the short term. The heat absorbed by the ground every day is still less than the heat lost, so the temperature did not rise immediately. The masses are used to counting nine from the solstice in winter, and every nine days is a "nine". Before and after "March 9th", the area was the least hot and the weather was the coldest, so it was said that "March 9th was cold".

A Brief Introduction to the Symbolic Significance of Winter Solstice

1, the winter solstice is a symbol of reunion.

The ancients said that "the winter solstice has passed and the Spring Festival is coming". After the solstice of winter, the days begin to get longer and longer, and people are looking forward to the arrival of spring. When the winter solstice comes, every family will get together and enjoy a sumptuous dinner to express their thoughts and blessings to their relatives and friends. This reunion atmosphere also reflects people's yearning for a harmonious and happy life.

The solstice in winter symbolizes that the days will get better and better.

There is also a moral of the winter solstice, that is, "the days will get better and better." After the winter solstice, although the weather is still cold, the time of the day begins to increase gradually. This symbolizes people's hopes and longings for the future. Whether it is life or career, people hope to usher in better development and harvest in the new year, and the winter solstice has become a node symbolizing a new beginning.
