spring equinoxes
March daylight equilibriums
Spring equinoxes is the plural of spring equinox—the moment when the sun crosses the celestial equator heading north, marking the start of spring in the Northern Hemisphere.
This occurs around March 20 each year.
The plural appears in astronomical or historical contexts comparing these events across years: The spring equinoxes of 2020 and 2021 fell on different dates.
