Technically September 30 is middle of Autumn
This is a valid point. Generally the definition of summer encompasses the months of June, July, and August in the northern hemisphere. But this definition varies for many parts of the world and even in the United States.
Reckoning by cultural festivals, the summer season in the United States is traditionally regarded as beginning on Memorial Day weekend (the last Weekend in May) and ending on Labor Day (the first Monday in September), more closely in line with the meteorological definition for the parts of the country that have four-season weather.
