In hot summer, many people want to cool off, and autumn will come soon. Beginning of autumn is actually an important solar term, which is of great significance to the old farmers. After this day, the weather will gradually turn cold and the rain will begin to decrease. This is the so-called crisp autumn. There are many interesting proverbs about rural beginning of autumn. The first sentence is that beginning of autumn is very cold in the morning and very hot at night.
What exactly does this sentence mean? If it is early autumn, the weather will be cooler, if it is late autumn, the weather will be hotter, which literally means, but how to define the morning and evening of early autumn and late autumn? Some people say that early autumn refers to the first few months in beginning of autumn, that is, June in the lunar calendar, and also refers to the last few months in beginning of autumn, usually July in the lunar calendar. But more people think that the morning and evening here does not refer to this, but refers to the time of day before noon 12, even after 12, which I personally think is the boundary of 12.
Many people may think, isn't beginning of autumn just a day? Why should it be around 12? Because the lunar calendar itself is a combination of yin and yang, the 24 solar terms are also the wisdom of our ancestors, and the 24 solar terms are determined by the position of the sun running on the ecliptic. Every 15 degree is a solar term, so we can calculate in detail where the sun goes, not just what day it is today. This year's beginning of autumn time is 3: 00 on August 8th 17, which means that this year's beginning of autumn belongs to early autumn, so the weather is chilly, so many people must have felt it.
