When I was a child, I often heard the old man say that the summer heat is not hot, but the summer heat is in the dog days. In the China lunar calendar, dog days are used to indicate the hottest time of the year. The calculation of dog days is more complicated. In some years, dog days are 30 days, and sometimes it is 40 days. There are 40 days in dog days this year, the first 10 day, the middle 20 days and the last 10 day. One thing is certain, the summer heat is basically in dog days. The dog days are the hottest days of the year, with the highest temperature and the strongest yang.
