Introduction: As a symbol of cold weather in winter, "number nine" is often concerned by people. And on December 22, the number of nine is approaching, and the old man said, "The coldest is only three or nine days", when is three nine?Why is it the coldest?
With the arrival of the winter moon, the day of "counting nine" is approaching. The number nine, also known as the winter ninety-nine, is a traditional Chinese folk festival, and it is also a method of calculating the date of cold days and spring flowers, representing the cold and long after entering the winter. Every year on December 21-23 of the solar calendar, when the winter solstice meets, it is the beginning of the number nine. During the number nine period, people will ** the weather of the whole winter according to the weather changes after the winter solstice, so the number nine is also a way of Chinese folk meteorology.
The number nine is a winter seasonal Xi, counting from the winter solstice, every nine days is nineteen, a total of nine nine eighty-one days, that is, eighty-one nine. After every ninety-ninety-eighty-one days, spring begins to arrive, and the weather gradually warms. This year's "number nine" starts on Friday, December 22 of the solar calendar, the tenth day of the 11th month of the lunar calendar.
Generally speaking, in the process of counting nine, people will do different activities according to different situations. For example, on cold days, people wear thick cotton clothes and sweaters, as well as warm items such as hats, gloves and scarves to keep their bodies warm. At the same time, people also make fires at home for heating, or use modern heating equipment such as electric heaters and air conditioners.
In rural areas, there are also some agricultural activities related to the winter season during the number nine season. For example, people will use this time to store some food and fuel for the winter, such as storing vegetables and fruits such as radish, cabbage, sweet potatoes, as well as chopping firewood and collecting hay. In addition, people will also use this time for some winter fishing.
In addition to these activities, the number nine is also related to some traditional culture and folk Xi. For example, during the number nine period, people will make some traditional festival foods, such as Laba porridge, Laba garlic, Laba vinegar, etc. In addition, people also engage in some folk games and entertainment activities such as snowball fights, snowman building, skiing, etc.
In other words, the number nine is an important winter seasonal Xi in Chinese folk, which represents the arrival of winter and the intensification of cold.
1929 did not shoot, 3949 walked on the ice, 5969 along the river to see the willow ......For the number nine, the indispensable thing is the "number nine song". During the counting of nine, the old man often said that "the coldest is only three or nine days", so when is the three nines?Why is it the coldest?
According to the time calculation, this year's "39 days" will start on Tuesday, January 9, 2024, that is, the 28th day of November in the lunar calendarThe "four or nine days" start from January 18, that is, the eighth day of the lunar month, the Laba Festival.
According to the ancients, January 9 to January 26, 2024 is the coldest time of the year. Because this period of time is "three-nine-forty-nine".
SoWhy is Sanjiu the coldest period?？This is mainly:Because the "39" period is the time when the surface temperature is the lowest
It is understood that the winter solstice is not only the beginning of the number nine, but also the day when the sun reaches the Tropic of Capricorn, when the days are the shortest and the nights are the longest. Then the direct point of the sun gradually shifted northward, and the daylight hours in the Northern Hemisphere gradually increased.
During this time, due to the shorter day, the light time becomes shorter, so the ground begins to absorb less heat during the day and dissipate more heat at night, which eventually leads to the heat not making ends meet, until.
Three. During the 9th and 49th periods, the heat of the ground reaches the minimum, and the surface temperature is also at the lowest. At this time, although the solar radiation has begun to gradually increase, the increase rate of the surface temperature is relatively slow due to the low surface temperature and the large specific heat capacity of the ground material.
For this reason, the Sanjiu period has become a period of frequent cold waves. A cold wave is a sudden southward movement of cold air masses from high latitudes, causing widespread severe cooling and snowstorming. During the Sanjiu period, due to the low surface temperature, once the cold wave moves south, it will cause the temperature to plummet, making Sanjiu the coldest period.
In short, although the saying that "the coldest is only three or nine days" is the experience of the older generation based on practice, it also has a certain scientific truth, which is worthy of everyone's reference and reference. In addition, during this period, everyone must pay attention to keeping warm and healthy, wear more clothes, rest more, and exercise more to adapt to the cold weather.
Well, that's all for the festival of "number nine" that I told you today. By the way, when do you think the coldest time of the year is?Do you think it's cold this year?You can leave a message, comment, and tell everyone what you think about it.
