What do you mean, years are just mellow?

Acacia day is in the long night, and the years are mellow, which means that the night is long and the heart is not exhausted, which is the best situation of the years; Thousands of years have passed and the world has changed. How much parting, how much missing.

Acacia day is in the long night, and the year is just right. It is generally used for winter solstice, winter solstice, also known as southern solstice, winter festival, sub-year-old and so on. It has two connotations: nature and humanity. It is not only an important solar term among the 24 solar terms, but also a traditional festival for ancestor worship in China. The solstice in winter is one of the eight festivals in four seasons, and it is considered as a big holiday in winter. In ancient times, there was a saying that the winter solstice was as big as a year.

The winter solstice is the 22nd solar term in the "24 solar terms", and the solar calendar reaches 270 degrees. Every year, the festival is held on 65438+February 2 1-23 in the Gregorian calendar. The solstice in winter is the extreme point of direct sunlight spreading to the south. From winter to the sun, the sun shines directly on the Tropic of Capricorn, and the sun is most inclined to the northern hemisphere, and the solar altitude angle is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest.

In winter solstice, although the sun is low and the days are short, the temperature in winter solstice is not the lowest in meteorology. In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice. Because of the great difference in climate in different parts of China, this winter climate is obviously late for most parts of China.
