The old almanac asks about the arrival time.

I believe everyone thinks it's very hot now, but the weather has just dropped, which many people think is very incomprehensible. Because sleeping symbolizes that the hottest time of the year is coming, but it has been a long time since summer. This kind of weather really makes people feel very hot, and even some people can't breathe smoothly. Sleeping is also important, because it is one of the 24 solar terms in a year, and it is said that it is also the hottest period in China's traditional calendar.

This is also a traditional custom in China. Everyone thinks that the hot weather is in the dog days, and once the dog days are over, it means that the weather will enter the autumn season. In fact, the dog days are divided into three types: initial, intermediate and final, so they usually last for forty days. In fact, the number of days of stay is not calculated according to utility or lunar calendar date, but according to the calendar method of cadres and branches. The diving time is different every year, which also requires some meteorologists to calculate according to the calendar method.

Therefore, in daily life, people always think that the weather is very hot, but the dog days have not yet arrived, because the weather predicted by the calendar is not the hottest weather. The time point of shortness of breath is relatively different between the Gregorian calendar and the lunar calendar, and many scholars who study meteorology say that it is relatively fixed on the Gregorian calendar. The summer solstice actually means that the sun shines directly on the Tropic of Cancer, which is also the longest day in the northern hemisphere.

Therefore, everyone said that through this calculation method, we can really calculate when the hottest days in summer are. For many people, they usually check the dates of dry branches and dry branches on the old calendar, so that they can know when it is the hottest time and it is convenient for them to take a summer vacation in advance.
