Vernal Equinox Marks Start of Spring in Northern Hemisphere on March 20, 2025

The vernal equinox, marking the astronomical start of spring in the Northern Hemisphere, will occur on March 20, 2025, at 11:01 AM. During the equinox, the sun's rays will fall directly on the equator, resulting in nearly equal day and night lengths globally. This event signifies the transition from winter to summer, with the Northern Hemisphere tilting towards the sun until the summer solstice. While the equinox provides roughly 12 hours of daylight and darkness, atmospheric refraction causes the actual date of equal day and night to occur a few days later. Traditions associated with the spring equinox often celebrate fertility and the renewal of nature.
