The spring equinox and fall equinox are similar in that both mark points in the year when day and night are approximately equal in length, occurring around March 21 and September 23, respectively. They signify the transition between seasons, with the spring equinox heralding the beginning of spring and the fall equinox marking the start of autumn.
