Winter Solstice, commonly known as “Winter Festival”, “Long Solstice Festival” or “sub-age” and so on. The winter solstice is an important season in the 24 solar terms of the lunar calendar, and it is also a traditional festival of the Chinese nation. In ancient times, people drifting away from home had to go home for the winter festival at this time.
The winter solstice lasts from December 21 to 23 of the Gregorian calendar each year. It is noteworthy that around the winter solstice, the Earth is located near the perihelion and travels at a slightly faster speed, which results in a year when the sun shines directly into the southern hemisphere about eight days shorter than the northern hemisphere, so the northern hemisphere in winter is slightly shorter than in summer.
According to documents, in the Spring and Autumn Period more than 2500 years ago, china had observed the sun with Tugui and determined the winter solstice. It is said that the winter solstice in the Tang and Song Dynasties was the day to worship the heavens and ancestors. The emperor would go to the suburbs to hold a celebration ceremony, and the people would worship their parents. After the Song Dynasty, the winter solstice gradually became a festival to worship ancestors and gods. On the winter solstice of the Ming and Qing dynasties, the emperor held a celestial ceremony called “winter solstice suburban day”. During this period, people also had the custom of offering sacrifices to ancestors and family meals. Therefore, the winter solstice is called “Xiaonian”. Winter Solstice is called “shorter day” or “shorter day”. Ancient people believed that winter solstice is the starting point of calculating 24 solar terms in our country; because the New Year is just around the corner when winter solstice arrives, so the ancients thought that the importance of winter solstice is no less than that of New Year.
