The eighteenth day of November in this year's lunar calendar is the winter solstice, the winter solstice is not only one of the twenty-four solar terms, but also a very important festival, before the Qin and Han Dynasties, the winter solstice was the first year of the year, the beginning of the yang qi, and the ultimate of the sun's southward travel. As the old saying goes, "The winter solstice is not over, but you want to break your leg when you want to eat", what does it mean?

What are the characteristics of this year's winter solstice?
The winter solstice is one of the twenty-four solar terms, which are divided into twenty-four equal parts according to the sun's ecliptic, which is a virtual large circle imagined by using the earth's orbit as a reference, which is a person standing on the earth to watch the sun's trajectory throughout the year. Since the Earth orbits the Sun from west to east, the Sun orbits the ecliptic from east to west, once a year.
The time for the Sun to orbit once in the ecliptic is equal to the time it takes for the Earth to rotate once, which is 365 days, 5 hours, 48 minutes and 46 seconds, so the common year of the solar calendar is 365 days, and the leap year is 366 days. One solar term is equal to fifteen degrees of the ecliptic, and twenty-four solar terms are exactly 360 degrees, so one degree of the ecliptic is greater than one day, and one solar term is greater than fifteen days, which is about equal to fifteen days and five hours.
It is precisely because of the extra five hours that the time of each festival is different. Sometimes in the morning, sometimes in the evening, it is based on the fixed degree of the sun's yellow longitude. For example, when the "Yellow Sutra" of the sun reaches 270 degrees, it is the time of the winter solstice, but that is only a time point, when this time point falls, that day is the winter solstice.
In fact, all the days that come with the operation of celestial bodies have this characteristic, such as the first day of the new year, only because the moment when the moon runs between the sun and the earth is on the first day, but the morning and evening are different.
At 11:59:9 p.m. on November 18 of this year's lunar calendar, the solar ecliptic longitude only reached 270 degrees, which is the time of the winter solstice. In the lunar calendar, in another minute it will be the nineteenth day, and in the dry calendar, the second day is already counted.
What is the relationship between the winter solstice and the spring?
The time of the winter solstice festival directly determines the time of the spring, and there are three solar terms between the winter solstice and the spring, that is, the winter solstice to the small cold, the small cold to the big cold, and the big cold to the spring. A solar term is not a complete fifteen days, but fifteen days are more than five hours more, then three solar terms are forty-five days and about sixteen hours more.
Therefore, if the time of the winter solstice intersection is before ten o'clock in the morning, the time of the Spring Festival will be advanced by one day, and if the time of the Winter Solstice Festival is ten days later, the time of the Spring Crossing will be postponed by one day. People start counting nine from the winter solstice, and after forty-five days, spring is established, so the time of spring is either six or nine heads or five or nine tails.
That is to say, the time of the winter solstice festival is before ten o'clock in the morning, and the spring is five or nine tails, and if the winter solstice is after ten o'clock, the spring is six or nine. This year's winter solstice festival is in the evening, so this year's spring is in the "six nine heads", the fourth day of the first month of the first month, which is often said to be "spring playing six or nine heads".
What is the difference between Li Chun in "Six Nine Heads" and "Five Nine Tails"?
In the past, people were more familiar with the climatic characteristics of winter, because from the winter solstice to count nine, not only with the fingers to count the number of days, but also "painting nine" and "writing nine", the so-called "painting nine" is to paint a hollow plum blossom, plum blossoms have nine flowers, each flower has nine petals, draw one flower a day, nine petals after the completion of the spring warm flowers.
The same is true of "writing nine", writing nine nine-stroke hollow Chinese characters and drawing one stroke every day. People in the "draw nine" and "write nine" at the same time, will also record the weather changes every day, a long time, it is found that the climate changes are also regular, generally in the thirty days of multiple cycle, meteorologically called "atmospheric rhythmic activity".
This means that the same weather will appear after thirty days, or sixty days later. For example, "the clouds cover the Mid-Autumn Moon, and the snow hits the yuan lantern", from the Mid-Autumn Festival to the Shangyuan Festival, it is also a multiple of thirty days. Although the "Five Nine Tails" and "Six Nine Heads" are only one day apart, the impact on the climate is relatively large.
As the saying goes: "Spring hits six or nine heads, the poor suffer out", "spring hits five or nine tails, old cattle tired and break their legs", "play spring" is LiChun, derived from the custom of "beating spring cattle", which means that if Lichun is five or nine tails, the cold weather will be advanced, and after Lichun, it is easy to fall into the spring cold, resulting in a reduction in grain production.
If the spring is in the sixth or ninth, the cold weather will recede, and it will not be easy to have a cold spring, and the grain will be easy to harvest. In the past, grain production was not high, and if they encountered a year of good wind and rain, people could barely eat enough, and if they encountered a year of famine, they would not be able to eat enough, let alone called Hanako?
The winter solstice is not too late, and it is necessary to run and break the leg
Because the time of the winter solstice festival determines the time of spring, the time of spring determines the harvest of grain. Therefore, the meaning of "winter solstice is not chen" is that the time of the winter solstice festival is before the hour, that is, between ten o'clock, that is, "spring hits five or nine tails", which will affect the harvest of grain, easy to appear spring cold, and hanako has to run a long way to have a bite to eat.
In fact, in the sixties and seventies, many people could not eat enough, and they could only eat white-noodle steamed buns in the New Year, and when they bought a little pork, they had to be refined into lard, put into a jar to eat slowly, and at that time, many children suffered from cold diarrhea due to eating lard. Even persimmon skins can be ground into noodles after drying and served as a staple food, I don't know if anyone remembers?
