What's the weather like on winter solstice?

Rain on the day of winter solstice means that the Spring Festival is sunny. If it is sunny, it means that the winter solstice is cloudy.

The winter solstice is a very important solar term in China lunar calendar, and it is also a traditional festival. Until now, there are still many places that have the custom of winter solstice. Winter solstice is commonly known as winter festival, long festival and sub-year festival. As early as 2500 years ago, during the Spring and Autumn Period, China observed the sun with soil gauge and determined the winter solstice. It is the earliest of the 24 solar terms, and the time is between February 22 and 23 in the solar calendar 12.

The winter solstice is the shortest day and the longest night in the northern hemisphere all year round. After the winter solstice, the days will get longer and longer. The ancients said to the winter solstice: the cathode is on, the sun is the spirit, the sun is south, the sun is short, and the shadow is long, so it is called the winter solstice. After the winter solstice, the climate in all parts of the country has entered the coldest stage, which is what people often say. There is a saying in China that it is cold on March 9th and hot in the dog.

The origin of winter solstice:

The winter solstice is the earliest of the 24 solar terms and is considered as the first of the 24 solar terms. The time is between 65438+February 2 1 to 23 in the Gregorian calendar every year. After the establishment of the Zhou Dynasty, Duke Zhou sent experts to measure the center of the country with an eight-foot soil gauge. After measurement, they designated the day with the longest shadow as the winter solstice and the shortest day as the summer solstice.

The winter solstice is the 22nd solar term among the 24 solar terms, and it is celebrated every year on June 65438+February 2 1 to 23rd 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 elevation angle of the sun is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest. The winter solstice is also a turning point for the direct point of the sun to return to the north. After this day, it went back, the direct point of the sun moved northward from the tropic of Capricorn, and the days in the northern hemisphere became longer day by day.
