Spring Equinox 2024 Season In. Cue the sunshine, birds, bees, and early spring flowers in the northern hemisphere. Equinoxes mark the start of spring and autumn.
It happens every march 20 or 21 (or march 19 if it’s a leap year like 2024 and you are in the eastern time zone or farther west). In 2020, the spring equinox was the first to occur on march 19 โ at least for those of us in north america โ since 1896.
