Why is the winter solstice called "Winter Festival"?

1, winter, commonly known as the "winter festival", there is an ancient saying that "the sun shines in winter", that is to say, from the day of winter, the yang gradually began to pick up.

2. The winter solstice is not only an important solar term in the twenty-four solar terms of the lunar calendar, but also a traditional festival of the Chinese nation. The winter solstice is a "winter festival". In ancient times, there was a saying that "the winter solstice is as big as a year". In ancient times, people wandering in other places had to go home for the winter festival at this time, which was called "returning home at the end of the year".

Winter solstice (alias: 1999, Winter Festival, Dragon Festival, Asian Year, English name: Winter solstice) is the 22nd solar term in the "24 solar terms", the longitude of the sun reaches 270 degrees, and the date falls on the 22nd or 23rd of February in the Gregorian calendar every year, which is a traditional festival of the Chinese nation.

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 solstice in winter is also a turning point for the sun to return directly to the north. After this day, there will be a "turn back", and the direct point of the sun will move northward from the tropic of Capricorn (23 26' s), and the daytime in the northern hemisphere will increase day by day.

The winter solstice marks the beginning of the cold season, so people begin to count nine to calculate the cold weather (folk proverb: "The summer solstice is three Geng, and the winter solstice is nine for everyone).
