202 1 What's the meaning of the winter solstice solar term?

1, the winter solstice means that the cold winter is coming. In winter solstice, the longitude of the sun is 270 degrees. On the solstice of winter, the sun shines almost directly on the tropic of Capricorn. Our northern hemisphere has the shortest day and the longest night, and it has begun to enter several cold days. Astronomy stipulates that this day is the beginning of winter in the northern hemisphere. After the winter solstice, the direct sunlight gradually moved northward, and the days in the northern hemisphere gradually became longer. As the proverb goes, eating noodles on the solstice in winter will make the day longer.

2. The winter solstice is an important solar term and traditional festival in the China lunar calendar. Until now, there are still many places that have the custom of winter solstice. The winter solstice is commonly known as "Winter Festival", "Dragon Solstice Festival" and "Asian New Year Festival". As early as 2500 years ago, during the Spring and Autumn Period, China had determined the winter solstice by observing the sun through the soil return, which was the earliest of the 24 solar terms. The time is between February 22nd and 23rd of Gregorian calendar 12.
