About First Day of Fall

The first day of fall (autumn) in the Northern Hemisphere coincides with the autumnal equinox, typically on September 22 or 23. Day and night are roughly equal in length, and temperatures begin to cool as the Earth tilts away from the sun. Autumn is celebrated in many cultures — harvest festivals, Oktoberfest in Germany, the Mid-Autumn Festival in East Asia, and Diwali in South Asia all cluster around this season. In the Northern Hemisphere, fall foliage peaks in October as deciduous trees change colour.
