is the date of the winter solstice fixed in the lunar calendar: it is not fixed. The winter solstice goes according to the time of the Gregorian calendar. There is no fixed time in either the Gregorian calendar or the lunar calendar. This is because the Chinese calendar officially uses the Gregorian calendar, and the lunar calendar is still used in large rural areas. This lunar calendar is a combination of yin and Yang. The lunar cycle used in the month and the solar cycle used in the 24 solar terms are solar terms. It should be said that it is solar terms. It is related to the solar calendar in the first half of the year when it falls on June and straight 11, and in the second half of the year when it falls on August and 23, because Chinese people call the lunar calendar, Solar terms are mixed with the lunar calendar. Most people think that solar terms are lunar, but actually solar terms are Gregorian. The twenty-four solar terms is an original cultural heritage created by the working people in China. It can reflect the changes of seasons, guide agricultural activities and affect the clothing, food, housing and transportation of thousands of families. Since 2000, most of China's main political activity centers have been concentrated in the Yellow River Basin, and the 24 solar terms have been established based on the climate and phenology in this area. Due to China's vast territory and changeable terrain, the 24 solar terms are only a reference for many regions. The 24 solar terms are divided according to the position of the sun in the ecliptic (that is, the earth's orbit around the sun). Depending on the sun starting from the vernal equinox (zero degrees of the Yellow meridian, at this moment the sun shines vertically on the equator), every 15 degrees forward is a solar term; It runs for a week and returns to the spring equinox. It is a return year, which is 360 degrees. Therefore, it is divided into 24 solar terms. The date of solar terms is relatively fixed in the Gregorian calendar. For example, the beginning of spring is always between February 3 and 5 in the Gregorian calendar. However, in the lunar calendar, the date of solar terms is not very easy to determine. Taking the beginning of spring as an example, it can be as early as December 15 of the previous lunar calendar and as late as January 15.
