What month is autumn?

Big autumn, according to farmers, is "the season of autumn harvest". Generally, the autumn harvest begins in September and basically ends at the end of the month.

Autumn begins at the beginning of autumn and ends at the beginning of winter. Autumn refers to beginning of autumn from July to September in the lunar calendar. It is the first 13 solar term among the 24 solar terms, and meets on August 7 -9 in the Gregorian calendar every year. Its beginning and end are the result of the operation of celestial bodies.

Beginning of autumn doesn't mean the extreme hot weather is over. Beginning of autumn is still in the summer heat period, and the summer heat will not come out until the second solar term in autumn. It's still very hot in early autumn. The watershed of summer heat is not in the solar terms in beginning of autumn. The most obvious change in autumn is that the leaves of vegetation change from lush green to yellow.
