At 7:44 a.m. exactly, the Vernal Equinox occurs. This is the official start of Spring for the Northern Hemisphere, when the Sun's incoming solar rays are more directed at us than "down under." The Sun's rays pass directly "over" the Equator at 7:44 a.m., meaning the Northern Hemisphere begins receiving more sunlight than the Southern Hemisphere. We pass into Spring and Summer, while the South passes into Fall and Winter.
