How to calculate Sanjiu: from winter to the next day 19 to the 27th.
The winter solstice begins to count to nine, which is what people call winter counting to nine. Counting nine days is nine, counting nine days is two nines ... Counting nine is nine, it will be warm at nine o'clock, and the sun will bloom.
"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.
People say that the cold is in nine and the heat is in the volt. Although the number nine is cold, it is different because our country is vast:
The "Jiujiu Song" in the middle and lower reaches of the Yellow River is: 1929 without a gun; Walking on the 3949 River; 5969 see willows along the river; Seven or nine talks, eight or nine geese come; 1999 and 1999, cattle are being farmed everywhere.
Jiangnan's "Jiujiu Song" is: 1929, meeting a husband; On March 27th, cymbals (an ancient musical instrument, meaning the fence crackled with cold wind) were played at the fence head. 4936, the night is like a heron (the night is cold like a crane); In 5945, the sun opened the door, and in 6954, poor children fought for spirit; In 7963, cloth sleeves were worn on the head; In 8972, the cat looked for the sun; Plow and rake go out together.
The coldest days are March 9 and April 9. In Jilin, dogs froze to death in March, 1949, while in Jiangsu, old people who picked up dung traveled all over the streets in March, 1949. It can be seen that the temperature varies greatly.
China is an important solar term in the lunar calendar and a traditional festival of the Chinese nation. The solstice in winter is usually called Winter Festival, Long Festival and New Year's Eve. As early as more than 2,500 years ago in the Spring and Autumn Period, China had observed the sun with the earth, and determined the winter solstice, which was the earliest of the 24 solar terms, and the time was between 0 and 23 in Gregorian calendar 65438+February 265438.
What do you mean three or nine days?
Three or nine days means the third "nine days" from the winter solstice, that is, the winter solstice after 19-27 days. In China, the season is counted on the ninth day of the ninth lunar month. The winter solstice is the first day of September 19, and every nine days is September 19. The first nine days are called September 19, the last nine days are called February 9, and so on. After 8 1 day on September 9, winter ends and spring comes, and the coldest period of the year is March 9. Therefore, it is very necessary to take good cold protection measures during the March 9th.
Why is it coldest in March and September?
During the winter solstice, the daytime is the shortest, the angle of direct sunlight on the ground is the smallest, and the sunshine intensity per unit area on the ground is also the smallest, so the ground gets the least solar heat every day, and the daily heat budget deficit on the ground has not reached the maximum. On the solstice after winter, although the day is growing day by day, the growth rate is very slow. From the winter solstice to the "March 9" period, the average daily growth is only about one minute. At the same time, the angle between the direct angle of the sun and the ground is slowly increasing. The daily heat budget of the ground is still in deficit, so it continues to lose heat and the ground temperature continues to drop. The deficit of total heat balance on the ground only reaches the maximum in the season of March 9. Because the temperature is mainly affected by the ground temperature, it leads to the lowest temperature in March 9 (of course, this is not the case all over the country, but every year, depending on the region and age). In addition, around March 9, the cold air mass in Siberia also developed to a very strong stage, and the frequent invasion of strong cold air is also one of the reasons for the low temperature.
The earth absorbs heat from solar radiation during the day and releases heat at night. In summer, you absorb more heat during the day and emit less heat at night, so you can accumulate some heat every day. In winter, less heat is absorbed during the day and more heat is released at night. Not only can you not accumulate it every day, but you also need to use some of the heat accumulated in summer. During the winter solstice, less heat is absorbed during the day, but there is still some stored heat on the earth. After the winter solstice, less and less heat is stored. By March 9, the earth's heat storage is the least in a year, so it is the coldest.
What food do you eat for three or nine days?
1, afraid of cold: it is best to eat ginger to drive away the cold.
Fear of cold is a common feature of many elderly people. Because people's metabolism slows down after aging, it is easy to form qi and blood deficiency. Therefore, autumn and winter are very rare opportunities for the elderly to treat diseases.
When it comes to tonic, some people think of ginseng, velvet antler and cordyceps sinensis, which are precious medicinal materials. Every time I go home to honor my parents during the New Year, I will buy these tonics. This is a wrong concept. The most common food is also the best medicine, and the cheaper the food, the better the curative effect.
2, kidney: chestnut porridge
Winter is the season of tonifying kidney. Kidney is very important in the five internal organs and is the foundation of health. People's aging is simply the weakness of the kidney. Therefore, winter is a good time to tonify kidney, resist aging and keep fit.
However, you can't eat supplements indiscriminately. There is also a misunderstanding among the people that tonifying the kidney requires eating organs related to reproduction, such as the kidneys and external genitalia of male animals. This is actually biased. The genitals and kidneys of male animals can't be eaten casually, and many vegetables and fruits also have the function of tonifying kidney. It is particularly important to note that it is not suitable for eating kidneys in winter, which is harmful and does not make up.
3. Qi: Every nine chickens.
Food supplement in winter is inseparable from meat. Although generally speaking, eating less meat is good for health, the elderly are weak and it is difficult to meet the needs of tonic by vegetarian diet. In winter, they should eat some meat properly. However, different meats are different. Chinese medicine studies meat very carefully. Different kinds of meat have different properties and tastes, so there is no need to eat all kinds of meat for tonic.
People who are healthy, not weak and not dry can eat more chicken in winter. As the saying goes, "every 9/kloc-0 chicken will make you healthy in the coming year." Chicken is slightly warm, tends to be dull, and has little stimulation to human body. Chicken can not only provide rich nutrition, but also resist the cold slightly in winter and prevent people from eating internal fire. It is a good product for health preservation in winter. Chicken is best stewed, and stewed chicken with mushrooms is a classic chicken stew.
