The March equinox, also known as the vernal equinox, occurs around March 20th or 21st in the Northern Hemisphere. During this time, day and night are approximately equal in length as the sun crosses the celestial equator moving northward. This event marks the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. The March equinox is significant for various cultural and agricultural reasons.
