We all know that as the saying goes, "cold is in Sanjiu, hot is in Sanfu". It is a popular Chinese meteorological proverb used to describe the coldest and hottest times of the year.
Cold in Sanjiu: refers to the coldest period of winter, which usually occurs during the "Sanjiu" day. According to the traditional Chinese arithmetic, counting from the winter solstice, every nine days is 19, so "39" is the 19th to 27th day after the winter solstice, about the beginning to mid-January of the Gregorian calendar. During this time, although the winter solstice day has the least sunshine, the heat lost by the ground is still greater than the heat absorbed, until the "39" time, the cold accumulated on the ground reaches its peak, so it feels the coldest time.
Heat in the dog days: In contrast, the hottest phase of summer is during the "dog days". The three dog days include the beginning, middle and end of the lunar calendar, and are generally calculated from the third Geng day after the summer solstice of the lunar calendar, about mid-July to mid-August of the Gregorian calendar. At this time, the sun shines directly on the northern hemisphere, and the high humidity caused by the evaporation of water from the ground, the heat is felt even more intensely, and it is the hottest time of the year.
Dog days, during this time the weather is not only very hot, but also humid, giving people a humid and muggy feeling. The word "Fu" here has the meaning that yin energy is forced by yang energy and hides underground, which also reflects that the weather is too hot, and people should reduce their activities to avoid heat stroke.
The three dogs are divided into primary, middle and last:
Chufu: Starts on the third Geng day after the summer solstice solar term and lasts for 10 days.
Middle volt: Immediately after the first volt, the length is variable, it may be 10 days or 20 days, depending on the time of the first Geng day before and after the beginning of autumn.
Last: Starting from the first Geng day after the beginning of autumn, it also lasts for 10 days.
The length of the mid-volt determines the total length of the dog days, which may be 30 or 40 days. This division is based on the ancient Chinese Ganzhi Chronicle method, which refers to the day with the prefix "Geng" in the Sexagenary Chronicle. The 2024 "Dog Days" timetable is here, and this year's dog days are not ordinary, so it is recommended that you prepare early!
The dog days of 2024 start on July 15 and last until August 23, for a total of 40 days.
First Days: Starts on July 15 and ends on July 24, 2024.
Mid-volcan: After the first volcane, it starts on July 25 and lasts until August 13, a total of 20 days.
Last Fushi: The last is Suofushi, which starts on August 14 and ends on August 23.
Is this year's dog days a "female volt" or a "male volt"?
According to previous information, the date of the ambush in 2024 is July 15, and the corresponding lunar date is the tenth day of the sixth lunar month, which is an even date, so according to the traditional division of "singular numbers are male, even numbers are female", this year is "female volt". There is a folk saying that the "male volt" may be hotter and the "female volt" is relatively cooler, but this statement is not scientifically conclusive, and the actual weather conditions will be affected by a variety of meteorological factors.
