Spring Equinox 2024 Usa

Spring Equinox 2024 Usa. The spring equinox (as well as autumnal equinox) is the moment when neither of the earth’s hemispheres is inclined towards or away from the sun. For those of us in the northern hemisphere, this was marked by the arrival of the vernal equinox (otherwise known as the “first point of aries“).
