Astronomical Autumn vs. Meteorological Autumn

Meteorological Autumn and Astronomical Autumn are two different ways of defining the seasons: Meteorological Autumn: Meteorological seasons are based on the calendar months and are primarily used by meteorologists and climatologists for consistent and simplified record-keeping and forecasting. In the meteorological definition, autumn is considered to be the three calendar months of September, October, and November in the Northern Hemisphere, and March, April, and May in the Southern Hemisphere.
