when does the equinox occur in the northern hemisphere
Equinox The equinoxes, along with solstices, are directly related to the seasons of the year. In the northern hemisphere, the vernal equinox (March) conventionally marks the beginning of spring in most cultures and is considered the start of the New Year in Hindu calendar and the Persian calendar or Iranian calendars as Nowruz (means new day), while the autumnal equinox (September) marks the beginning of autumn.[4]
Equinox On the day of an equinox, daytime and nighttime are of approximately equal duration all over the planet.

The word is derived from the Latin aequinoctium, from aequus (equal) and nox (genitive noctis) (night).
