The fall equinox arrives on Sept. 22, 2022, at 9:04 P.M. EDT in the Northern Hemisphere. The equinox occurs at the same moment worldwide.

Autumn is right around the corner for everyone in the Northern Hemisphere, while those in the Southern Hemisphere are gearing up for warmer spring weather. 

Depending on the part of the world in which you live, the season will change on either Sept. 22 or 23. That’s because the equinox isn’t a daylong event. Rather, the equinox is defined by the position of the Earth and the sun at a particular moment in time.
