"'Equinoxes are associated with the changing seasons,' NASA explained. 'In March, Northern Hemisphere observers welcome the longer, warmer days heralded by their vernal, or spring, equinox.'"
"'The date for that split depends on your latitude, and may occur a few days earlier or later than the equinox itself,' NASA explained. 'The complicating factors? Our Sun and atmosphere!'"
"'The Sun doesn't neatly wink on and off at sunrise and sunset like a light bulb, and so there isn't a perfect split of day and night on the equinox - but it's very close,' NASA added."
The Vernal Equinox occurs at 14:46 GMT, signaling the transition from winter to spring. Observers in the Northern Hemisphere experience longer, warmer days, while those in the Southern Hemisphere face shorter, cooler nights. The equinox happens twice a year, with equal sunlight on both hemispheres. However, the length of day and night may not be perfectly equal due to atmospheric refraction, which adds minutes of light. The next equinox will occur on 20 March 2026 at 14:46 UTC.
