What is the September Equinox?

An Equinox is an astronomical event that happens twice a year, once in spring and once in autumn. The September Equinox is the moment in time when the Sun stands directly above the equator while crossing it from the North towards the South. For the Northern Hemisphere it is the Autumn Equinox as it is the moment when Summer ends and Autumn begins. For the Southern Hemisphere it is the Vernal Equinox, the moment when Winter ends and Spring begins. The September Equinox usually occurs every year between the 21st and 24th of September.

Facts about the Equinox

Impress your family and friends with your knowledge about the Equinox. Check out the facts below and discover even more about this astronomical event.

  1. Equinoxes are not day-long events, even though many choose to celebrate all day.
  2. The Equinox dates vary because of the difference between how the Gregorian calendar defines a year (365 days) and the time it actually takes for Earth to complete its orbit around the Sun (about 365 and ¼ days).
  3. The term equinox comes from the Latin words aequus, meaning equal. And nox, meaning night.
  4. The Full Moon closest to the September Equinox, the Harvest Moon, is astronomically special. This is because the time between one moonrise to the next becomes shorter around this period.
  5. As the September Equinox rolls by, the chances to see the aurora borealis (Northern Lights) increases for those located at high Northern Hemisphere latitudes.
