What are early autumn and late autumn? How to distinguish them?

You can judge whether it is early autumn or late autumn according to the beginning of autumn time in the lunar calendar.

In the solar calendar, the time in beginning of autumn is fixed, which falls on August 7th or 8th every year, but it may be much worse in the lunar calendar. Based on the seventh month of the lunar calendar, if beginning of autumn has not entered the seventh month of the lunar calendar, it is called early autumn; On the other hand, if it has entered the seventh month of the lunar calendar, it is called late beginning of autumn.

As the name implies, "beginning of autumn" is "the beginning of autumn in a year" and is 13 of the 24 solar terms of the lunar calendar. Usually, beginning of autumn is on August 7th or 8th every year. However, this is not the "beginning of autumn" where the weather turns cold immediately. It just means that at this time of the year, the weather is getting colder, and the temperature difference between day and night begins to increase. Even if it is very hot during the day, there will be chills at night.

In fact, after beginning of autumn, there was a saying that "the autumn will kill the old cow". Because beginning of autumn is in the dog days every year, the weather will officially get cold only after the hottest dog days of the year have completely passed. As the saying goes, "beginning of autumn is cold in the morning and beginning of autumn is hot at night", which means that the weather in beginning of autumn has a great influence on the morning and evening.
