people will not feel strange when talking about the winter solstice, because this is not only China's traditional 24 solar terms, but also China's traditional festival. Is the winter solstice the same day every year? Is the winter solstice and count nine a day? Let's learn about this festival together with the old yellow calendar!


is the winter solstice the same day every year: not necessarily, the winter solstice is from December 21 to 23 of the Gregorian calendar every year. It should be noted that before and after the winter solstice, the earth is located near the perihelion and runs slightly faster, which makes the time when the sun shines directly on the southern hemisphere about 8 days shorter than that in the northern hemisphere. Therefore, the winter in the northern hemisphere is slightly shorter than that in summer. From the winter solstice to the next winter solstice, it is equivalent to a regression year. Its length is 365.2422 days. The accumulation of decimals and the setting of leap years make the date of the winter solstice change slightly.


is the winter solstice and counting nine one day: counting nine is the first day from the winter solstice. Number nine is a more suitable miscellaneous solar term in northern China, especially in the middle and lower reaches of the Yellow River. From the day of the winter solstice, it enters the "count nine", commonly known as "jiaojiu". After that, it is a unit every nine days, which is called "Nine". After nine "Nine", it is just 81 days, which is "out of nine". At that time, the flowers bloom in spring. The winter solstice "Jiu Jiu Xiao Han song", commonly known as "Jiu Jiu song", vividly records the climate and phenological changes between the winter solstice and the next spring equinox, and also expresses some laws of agricultural activities. The widely circulated "song of eliminating cold in 1999" says: "if you don't do it in 1929, walk on the ice in 3949, look at willows in 5969, the river in 799 opens, geese come in 899, and cattle go everywhere."
