vernal equinoxes
March daylight equilibriums
Vernal equinoxes is the plural of vernal equinox—the moment in spring when the sun crosses the celestial equator and day and night are approximately equal in length.
In the Northern Hemisphere, this occurs around March 20 or 21; in the Southern Hemisphere, around September 22 or 23.
The term often refers to the astronomical events across multiple years: Scientists have tracked vernal equinoxes for millennia.
