In 2017, fall begins on September 22rd (at 20:02 UTC) for countries in the Northern Hemisphere. The date may be different for you based on what time zone you live in. This chart reflects the UTC time zone. Note: Equinoxes are opposite on each side of the equator.
In North America, summer is often fixed as the period from the summer solstice (June 20 or 21, depending on the year) to the fall equinox (September 22 or 23, again depending on the year). Therefore, Sept. 22 was the last day of summer and the beginning of the 2010 autumnal equinox, which officially began at 11:09 p.m. EST., the full moon having peaked the following morning at 5:17 a.m. EST which marked it as the first day of fall in the Northern Hemisphere.
