For some reason, I thought that the equinox was always on the 21st. Always interesting to learn something new. The March equinox occured on March 20 this year, marking the beginning of spring in the northern hemisphere and fall (autumn) in the southern hemisphere from an astronomical viewpoint. The March equinox occured at 17:32 (or 5:32pm) at Coordinated Universal Time (UTC).
This illustration, which shows an example only of the March equinox, is not to scale.Twice a year, around March 20 or 21 and September 22 or 23, the sun shines directly on the equator and the length of day and night are nearly equal in all parts of the world. These two days are known as the March (vernal or spring in the northern hemisphere) equinox and the September equinox.
