Fall equinox is another name for the equinox also known as autumnal equinox and September equinox. An equinox is the moment in time (not a day-long event) when the Sun stands directly above the equator and day and night are of approximately equal length. For the Northern Hemisphere, the fall equinox is the moment when summer ends and fall (autumn) begins, while for the Southern Hemisphere it is the moment when winter ends and spring begins.

In the Northern Hemisphere the fall equinox occurs every year on September 22 or 23. Very occasionally it can also fall on September 21 or 24. The dates given on this page are based on Coordinated Universal Time (UTC), which for practical purposes is equivalent to Greenwich Mean Time (GMT). While the fall equinox occurs at the same moment in time all over the world, the date and local time differ from place to place depending on the year and a location's time zone. For locations that are ahead of UTC (further east) it may fall on the day after, and for locations that are behind UTC (further west) it may fall on the day before. To find out the exact date and time of the fall equinox 2017 in your area use this seasons calculator.

The fall equinox is one of four days (two equinoxes and two solstices) throughout the year that mark the beginning of a new season. The other days are the spring equinox (beginning of spring), the summer solstice (beginning of summer) and the winter solstice (beginning of winter).
