What is the solar term from winter solstice, and the time from winter solstice is annual?

The time of winter solstice is not fixed.

The winter solstice is the most important of the 24 solar terms. According to the Gregorian calendar, the winter solstice is on February 22-23 every year, 12. On this day, the sun moves to the longitude of 270 degrees, with the southernmost latitude. The sun shines directly on the Tropic of Capricorn, with the shortest day and the longest night in the northern hemisphere (in the Arctic Circle, it is night all the time).

On the day of winter solstice, the height of the sun at noon in the northern hemisphere is also the lowest. For example, in Beijing, the height of the sun is only 26 42', because the shadow at noon is the longest, so it is also called "growing to the sun". China attached great importance to the winter solstice in ancient times, and stipulated that the same month as the winter solstice was the "sub-month", which was the first branch of the twelve solar terms. Therefore, the winter solstice is still a traditional festival, commonly known as "Winter Festival" and "Dragon Solstice Festival".

The winter solstice is as big as a year;

The winter solstice, with both natural and humanistic connotations, is not only an important solar term among the 24 solar terms, but also a traditional folk festival in China, which is known as "the winter solstice is as big as a year".

The solstice in winter is the starting point for the return of the sun. Since the winter solstice, the height of the sun has risen, and the day is getting longer and longer. The winter solstice marks the rebirth of the sun and the movement of the sun back and forth into a new cycle, so the ancients regarded the winter solstice as a "good day".

Among the eight festivals, the solstice in winter is as important as New Year's Day in spring. In southern China, there are customs of offering sacrifices to ancestors and enjoying the winter solstice. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.

People have always attached great importance to the winter solstice festival. In the pre-Qin period, the customs and cultures of the north and the south were different, and the customs of various places had not been integrated and popularized. Many festivals have a history, but they are not recorded. Many ancient festivals and customs are rarely recorded in books.

According to the existing works, the people of Zhou Dynasty (Shaanxi area) took November in winter as the first month and November 1 in winter as the beginning of the year. The 1 1 month 1 day of Zhou people in winter coincides with the date of winter solstice in the "twenty-four solar terms" of the current lunar calendar1month, so it is said that Zhou people have been in the winter solstice since the Zhou period (1/kloc-0.
