Sihaiwang: which is the hottest in summer or summer? As the saying goes: 'heat up and down, steam up and boil down'. This sentence vividly reflects the hot degree of hot summer. So which is the hottest, Xiaoshu or Dashu? Let's take a look at it with Xiaobian~
Which is the hottest, Xiaoshu or Dashu
Comprehensive overview
The arrival of the solar term of summer heat marks that it will enter the hottest stage in summer, but the question about whether it is a small summer heat or a big summer heat can tell you exactly that, of course, it is a little hotter. The ancients thought that during Xiaoshu, it was not the hottest time of the three dog days of the year, so it was called Xiaoshu. Every year around July 7, when the sun reaches 105 & deg; longitude, the solar term of summer heat begins. At 11:41:47 on July 7, 2018, Xiaoshu is on May 24, 2018 in the lunar calendar. Sunstroke is one of the 24 solar terms of the lunar calendar. From July 22 to 24 of the lunar calendar, the sun reaches the Yellow longitude 120 & deg;, indicating that the weather is extremely hot. The solar term of sunstroke is around the "middle volt" in the "three dog days", which is the hottest period of the year and the crops grow fastest. This year, the great summer of 2018 is 05:00:16 on July 23, and the lunar calendar is June (small) 11, 2018
On the hottest three summer days
As the saying goes, 'cold in 39, hot in 3 volts'. The "three volt" is composed of the first volt, the middle volt and the last volt. The third day after the summer solstice is the first day of the first fall, and the fourth day after the 10th day is called Zhongfu. If the fifth day is before the beginning of autumn, Zhongfu will take 20 days, commonly known as two Zhongfu. If the fifth day is after the beginning of autumn, Zhongfu will take 10 days. The first day after the beginning of autumn is called the last. The "three dog days" is the highest temperature in a year, because the surface humidity becomes larger, the heat absorbed every day is more, the heat emitted is less, and the heat of the surface layer accumulates, so it's hotter day by day, when the accumulated heat of the ground area reaches the highest peak, the weather is the hottest, and the "bitter summer" as people call it is at this time.
Dog days in 2018: 40 days in total
The three volt days of each year are different. Usually, the three dog days begin after the solar term of summer heat. Because the two periods are hot, we should pay attention to heatstroke prevention and health preservation.
