Today's winter solstice, why is it said that the winter solstice is as big as a year?

The winter solstice is as big as a year, because it is a very important solar term and a traditional festival of the China lunar calendar. The solstice in winter is also the most leisurely time of the year. In the farming society, there is basically no farming at this time, and the family can get together in harmony. In the new year, winter has come and spring planting has begun, so it is not as leisurely as the winter solstice.

Winter solstice is one of the "24 solar terms". "Twenty-four solar terms" and "December construction" are the basic contents of the calendar, which were concluded in ancient times (or ancient times). According to ancient records, Emperor Tiandi began to determine his age in the name of cadres and branches. "Twenty-four solar terms" is a special festival in the calendar, indicating the season, phenology, climate change and the establishment of "December construction".

The ancient "Twenty-four solar terms" were determined by the direction of the top of the Beidou bucket handle. One-year-old is divided into "Twelve Chens" in the official calendar (built in December). "Building" represents the direction of the top of Beidou bucket handle, and bucket handle turns to "Twelve Chens" in turn. In traditional culture, the branch is linked with the time position of gossip, and the yin position is the "root position" of gossip the day after tomorrow. It is the position at the end of the year and the beginning of the year, representing the end and the beginning, such as Yi Shuo Gua Zhuan: "The root, the divination in the northeast, is also the beginning of everything."

Therefore, bucket handle starts from the north of due east (Yin position, gossip position the day after tomorrow) and makes a circle through the south, west and north, which is a cycle. It began in the beginning of spring and ended in the great cold. When bucket handle points to the "lower" position due north, it is the solstice winter solstice.
