What Seasons Do We Have Equinoxes?

Spring and fall, or autumn, begin on equinoxes, days that have equal amounts of daylight and darkness. The vernal, or spring, equinox falls on March 20 or 21, and the autumnal equinox is on September 22 or 23. The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere.

What seasons are equinoxes?

So, in the Northern Hemisphere you have:
  • Vernal equinox(about March 21): day and night of equal length, marking the start of spring.
  • Summer solstice (June 20 or 21): longest day of the year, marking the start of summer.
  • Autumnal equinox(about September 23): day and night of equal length, marking the start of autumn.

What are the two equinoxes?

On Earth, there are two equinoxes every year: one around March 21 and another around September 22. Sometimes, the equinoxes are nicknamed the “vernal equinox” (spring equinox) and the “autumnal equinox” (fall equinox), although these have different dates in the Northern and Southern Hemispheres.
