The weather at the end of the new year this year

People often say, "it's cold for nine days, but it's cold for three or nine days." Now it has entered the "March 9th", which is the coldest time of the year. As we all know, it is the coldest time for people to feel in March and September. Three or nine days is easy to calculate. Every year, on the day of winter solstice, you start counting to nine. After that, as long as you are familiar with the traditional solar terms in China, you will know the schedule of cold and heat. This is: "1929 did not shoot, and walked on the ice in 3949. [Look at the willows by the river in 5969, open the river in 79, swallow in 89, and cattle everywhere in 99. " . This means that because the earth has accumulated cold and hot energy some time ago, there will be 40 days of coldest weather from winter to the future; 18 solstice after beginning of winter, stiff hands and feet; The period from 18 days after beginning of winter to 36 days 18 days is the coldest period in a year, with the river surface frozen and the river blocked. Once winter comes to 18 days from 36 days to 54 days in the future, willows along the river will sprout new buds and the climate will get warmer; From winter to the 54th day to the 63rd day, swallows fly back to the north from the south. From winter to 63-72 days in the future and beyond, the weather will be completely warm after spring ploughing. There is a thousand-year-old proverb in Pingdingshan, Henan Province (the capital of the Three Kingdoms): "1929, don't make moves, walk on the ice in 3949, watch the willows cross the river in 5969, wash your hands and cross the river in 7989, and the old man stands on the wall in 998 1 year, not afraid of cold, but afraid of hunger." "March 9th" refers to the third "nine days" after the winter solstice, that is, the 19th to 27th days after the winter solstice. There is a saying "Jiujiu" in the China lunar calendar, which is used to calculate the seasons. The calculation method is from the solstice of winter (counting from the solstice of winter, which means the beginning of cold), every nine days are called a nine, the first nine days are called a nine, the second nine days are called a 29, and so on until the ninth nine days, when the number reaches 998 1 day. At this time, winter has passed and spring has arrived. Generally, it is the coldest in "Sanjiu". "The third nine days after the winter solstice" refers to "399", which is also the day when "399" and "499" intersect, not "399".
