Brief introduction of winter solstice in the twenty-four solar terms

The winter solstice is the earliest of the 24 solar terms, and it ranks first among the 24 solar terms. The traditional calendar takes five days as a period, three periods as a section or breath, and a year is divided into twelve sections and twelve gases, which are collectively called twenty-four solar terms. As for the solstice of winter, The Episode of July 72 says: The last hidden gas is extreme at this point. On the day of winter solstice, the sky is south, the days are short and the shadows are long, so it is called winter solstice.

Astronomy also regards the winter solstice as the beginning of winter in the northern hemisphere. The solstice in winter marks the extreme of yin and the beginning of yang, but the temperature will continue to drop in the short term because the heat radiated from the sun to the ground is less than that radiated from the ground to the space. Therefore, the solstice of winter is also the beginning of cold. During the Yin and Zhou Dynasties, it was stipulated that the day before the winter solstice was the end of the year. Because the first month of the week calendar is 1 1 month of the summer calendar, there is no difference between New Year's greetings and Chinese New Year's, so the winter solstice is also called "Asian New Year", which is essentially equivalent to today's Spring Festival.

The ancients believed that the solstice in winter was an opportunity for chaos and recovery. After winter is the beginning of a year, and Lu even said that winter is as big as a year, which also shows that the ancients attached importance to winter. It was not until Emperor Wu of the Han Dynasty adopted the summer calendar that the first month was separated from the solstice in winter. It can be said that the "Winter Festival" only existed after the Han Dynasty. In order to distinguish it from "saying goodbye to the old and welcoming the new" on the eve of the Spring Festival, the day before the winter solstice is called Xiaozhi or Xiaodong, and some of them are called "adding years" and "dividing years". The solstice winter is called the long winter. The day after winter, the solstice and even the day are named.
