The fall equinox, also known as the autumnal equinox, marks the official start of autumn in the Northern Hemisphere. It occurs when the sun crosses the celestial equator, making day and night nearly equal in length everywhere on Earth. For 2026, this event is set for Tuesday, September 22, at 8:05 PM EDT (or 00:05 UTC on September 23), depending on your time zone.

What Is the Fall Equinox?

The equinox happens twice a year—spring and fall—due to Earth's 23.5-degree axial tilt as it orbits the sun. In September (Northern Hemisphere), the sun shifts south of the equator, ushering in shorter days and cooler weather. This isn't exactly 12-hour days everywhere due to atmospheric refraction, but it's close.

  • Northern Hemisphere : Autumn begins; leaves change, harvest season peaks.
  • Southern Hemisphere : Spring starts instead.

Fun fact: Myths like balancing an egg only on equinox day are just that—myths. It works any day with steady hands!
