Autumn or fall season is one of the four pleasant seasons. Autumn symbols the evolution from summer into winter, in September or March when the coming of night turn into obviously prior. The equinoxes may be probable to be in the core of their personal seasons, but warmth interval means that seasons come out later than dates calculated from a purely astronomical perspective. The actual lag varies with region. Some cultures regard the autumnal equinox as “mid-autumn”; others with a longer lag treat it as the start of autumn. Meteorologists use a definition based on months, with autumn being September, October and November in the northern hemisphere, and March, April and May in the southern hemisphere.
