The arrival of winter is always accompanied by severe cold and cold weather, and "number nine" is a folk term used to calculate the cold degree and progress of winter. Depending on the number nine method, we can ** the cold time period and the coldest hour of this year's winter. So, when did this year's number nine start?When is it the coldest?Below we will analyze three different methods of counting nine and which one is more reliable.
According to the most common method of counting nine, counting nine begins on the day of the winter solstice. After the winter solstice, although the days gradually become longer, the growth rate is slower. The heat budget after the winter solstice is still in deficit, and the ground continues to lose heat, and the temperature gradually drops. Therefore, the coldest times tend to occur on the "39 days" and "49 days", that is, between January 17 and February 3, 2024 in the Gregorian calendar. And according to this method of counting nine, we can conclude that the coldest period of the year should be in late January to early February.
In another folk method of counting nine, the number nine is divided into "male nine" and "female nine". According to this method, if the winter solstice solar term is an odd-numbered day of the lunar calendar, that is, the count of nine will begin on that day;Whereas, if it is an even-numbered day, the count of nine starts the next day. In addition, according to the concept of yin and yang odd and even, odd-numbered days are considered masculine, and "Gong Jiu" represents a relatively warm period, while even days are considered feminine, and "Mother Nine" represents a colder period. In this way, this year's winter solstice is the 10th day of November, which is an even-numbered day, so according to this method, the winter will be relatively cold.
In ancient times, the most accurate way to count nine was "counting nine on the day of the winter solstice". This method is based on the "Ren Ri" in the ancient Ganzhi Chronology. According to this method, the first day after the winter solstice begins to count nine, and every nine days is a "nine" until ninety-nine eighty-one days. "Nine peach blossoms" is the end of the cold winter and the weather is getting warmer. However, due to the fact that the Ganzhi chronology does not exactly coincide with the Gregorian calendar time, the time of counting nine varies from year to year, so some doubts have arisen about the accuracy of this method. However, there are still a few people who believe that this is the most reliable method of counting nine, but it is a little cumbersome to calculate.
On the whole, each method has its own unique principles and characteristics, but which one is more reliable still needs to be further verified and verified. After all, the development of meteorology has made it possible to predict climate change through modern scientific means such as observation and **, and the folk method of counting nine is not so much accurate weather ** as an interesting meteorological phenomenon that people have summed up based on traditional experience. Therefore, according to your own interests and preferences, you can choose what you think is a more reliable way to observe meteorological changes.
All in all, the coldest period of this year's winter is expected to be from late January to early February, and the exact extent of the cold needs to be further observed. For people, whether they believe in the traditional method of counting nine or rely on modern meteorology**, they should be prepared to keep warm, protect their health, and have a warm and pleasant winter. Whether it is an ancient folk proverb or a modern science and technology, it is people's exploration and cognition of nature, and only by continuous exploration can we better adapt to and respond to changes in the natural environment. Let's look forward to the arrival of this winter, feel the changes of the four seasons, and cherish the good times that life gives us.
