Detailed explanation-1: -These events are referred to as Equinoxes. The word equinox is derived from two Latin words-aequus (equal) and nox (night). At the equator, the sun is directly overhead at noon on these two equinoxes.

Detailed explanation-2: -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.

Detailed explanation-3: -While the solstices result in a change of the length of night and day, the equinoxes do not. The summer and winter solstices result in the longest and shortest day of the year respectively while the equinoxes result in an equal amount of daylight and darkness received all across the earth.

Detailed explanation-4: -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. More items
