When is the solstice in the winter of 2020?
Winter solstice, also known as short solstice, winter festival, year-ending, winter worship, etc., has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional folk festival 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. There is an ancient saying that the solstice in winter is as big as a year, so the ancients called it "off-year" or "off-year". The custom of winter solstice varies in content or details due to different regions. In some areas along the southern coast of China, there are customs of offering sacrifices to ancestors and feasting on the winter solstice. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.
Astronomical significance of winter solstice
According to modern astronomical science, during the winter solstice, the sun moves to 270 (winter solstice), and the position where the sun directly hits the ground reaches the southernmost point of the year. The sun shines almost directly on the tropic of Capricorn (also known as the winter solstice daily line), and the sun is most biased towards the northern hemisphere. Therefore, the winter solstice is the place with the shortest day and the longest night in the northern hemisphere. The higher the latitude, the shorter the day and the longer the night.
