The March equinox is almost upon us, which will usher in astronomical spring in the Northern Hemisphere and astronomical fall in the Southern Hemisphere.
This year, the vernal equinox, or spring equinox, occurs at 10:46 a.m. EDT (14:46 UTC) on March 20 in the Northern Hemisphere, according to Time and Date. Because equinoxes are global events governed by Earth's tilted axis relative to the sun, the March equinox occurs at the same moment across the globe.
