The amount of daylight each day will continue to increase until the summer solstice in June, during which the longest period of daylight occurs. While the Sun passes overhead, the tilt of the Earth is zero relative to the Sun, which means that Earth’s axis neither points toward nor away from the Sun. (Note, however, that the Earth never orbits upright, but is always tilted on its axis by about 23.5 degrees.)Īfter the spring equinox, the Northern Hemisphere tilts toward the Sun. Although in most locations (the North Pole and Equator being exceptions) the amount of daylight had been increasing each day after the winter solstice, after the spring equinox, many places will experience more daylight than darkness in each 24-hour day. If you were standing on the equator, the Sun would pass directly overhead on its way north.Įquinoxes are the only two times each year that the Sun rises due east and sets due west for all of us on Earth! It’s called the “celestial” equator because it’s an imaginary line in the sky above the Earth’s equator. On the March equinox, the Sun crosses the celestial equator going south to north. On the equinox, Earth’s two hemispheres receive the Sun’s rays about equally. With the equinox, enjoy an increasing amount of sunlight hours, with earlier dawns and later sunsets! See your personalized Sun rise and set calculator. On the equinox, the length of day and night is nearly equal in all parts of the world. The word equinox comes from the Latin words for “equal night”- aequus (equal) and nox (night). What Does Spring “Equinox” Mean, Exactly? *Due to time zone differences, this equinox will technically occur on the next day in some parts of the world. In the Southern Hemisphere, the March equinox marks the start of autumn, while the September equinox marks the start of spring. EDT. This marks the return of spring to the Northern Hemisphere. In 2022, the March equinox happens on Sunday, March 20, at 11:33 A.M. → What sort of weather will spring bring? Check out our Spring Forecast and new April Forecast to find out! When Is the First Day of Spring? After this date, the Northern Hemisphere begins to be tilted more toward the Sun, resulting in increasing daylight hours and warming temperatures. (In the Southern Hemisphere, it’s the opposite: the March equinox marks the start of autumn, as the Southern Hemisphere begins to be tilted away from the Sun.) This event marks the start of the spring season in the northern half of the globe. In the Northern Hemisphere, the March equinox (aka spring equinox or vernal equinox) occurs when the Sun crosses the equator line, heading north. Advertisement What Is the Spring Equinox?
