About Fall (September Equinox)

The September equinox, the astronomical start of Northern Hemisphere autumn, computed each year from the sun's position.

Fall (September Equinox) is the moment the sun reaches a particular longitude in its apparent path, calculated astronomically for each year. The date can shift by a day between years because the tropical year is not a whole number of days.
