The solstice in winter is between heavy snow and slight cold solar terms.

The winter solstice in 24 solar terms is one of the important traditional festivals in China, which usually falls on February 20th or 22nd of Gregorian calendar 65438+265438. The winter solstice is the last of the 24 solar terms and the beginning of winter. On the winter solstice, the sun reaches 270 degrees, which is also the shortest day and the longest night in a year.

In ancient times, the winter solstice was an important festival, and people held various celebrations, the most important of which was offering sacrifices to ancestors and gods. People will hold sacrificial ceremonies at home or in temples to show their respect and gratitude to their ancestors and gods. In addition, people will carry out some special customs, such as eating jiaozi, drinking glutinous rice balls and baking sweet potatoes, to celebrate this important festival.

The origin of solar terms

China's astrological culture has a long history and is profound. The ancients began to explore the mysteries of the universe very early, and thus deduced a complete and profound star-watching culture. Twenty-four solar terms were originally formulated according to the bucket handle rotation direction of the Big Dipper, which rotates circularly and is closely related to the seasonal changes.

The Big Dipper consists of seven stars, namely Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang. Named for its twists and turns. The Big Dipper is an important astrological sign in the northern hemisphere (China is located in the northern hemisphere). The natural rhythm of the corresponding area in the northern hemisphere gradually changed in the repeated rotation of the Big Dipper, which became the basis for ancient people to judge the seasonal changes.

"Twenty-four solar terms" is a special festival to express the natural rhythm changes in the dry calendar and establish "December" (monthly order), which is a solar month based on "Twenty-four solar terms".
