What does the solstice mean in winter? On the origin of solar terms in winter solstice.

It is an important solar term among the 24 solar terms, and it is also a traditional folk festival in China. From winter to the sun, the solar calendar reaches 270, and festivals are held every year on the Gregorian calendar 65438+February 2 1-23. Winter solstice is one of the eight festivals in a year. In ancient times, there was a custom of "eight festivals" to worship the gods and ancestors. The solstice in winter is considered as a big holiday in winter.

There is a folk saying that the solstice in winter is as big as a year, so the ancients called it "sub-year" or "off-year" In some coastal areas of southern China, the traditional custom of offering sacrifices to ancestors during the winter solstice is still continuing. In some areas of northern China, it is a custom to eat jiaozi every winter solstice.

The winter solstice marks the minimum height of the sun and the shortest day in the northern hemisphere, but the temperature in winter solstice is not the lowest. On the solstice of winter, the sun shines directly on the ground and reaches the southernmost tip 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, in all parts of the northern hemisphere, the winter solstice is the shortest day in a year, and the farther north, the shorter the day. It is worth noting that around the winter solstice, the earth is located near the perihelion, and its running speed is slightly faster, resulting in that the time of direct sunlight in the southern hemisphere is about 8 days shorter than that in the northern hemisphere in a year, so the winter in the northern hemisphere is slightly shorter than that in summer.
