Spring Equinox Marks Start of Season, March 20, 2025

The vernal equinox occurred on March 20, 2025, marking the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. During the spring equinox, the Sun crosses the celestial equator from south to north, resulting in nearly equal amounts of sunlight in both hemispheres. While most areas have experienced increasing sunlight since the winter solstice, the spring equinox signifies a period where many locations will have more daylight than darkness each day, continuing until the summer solstice in June.
