Spring 2025 technically begins at 5:01 a.m. Eastern time that day as the sun moves directly over the Earth’s equator — the central line between the North Pole and the South Pole — bringing almost equal minutes of daylight and darkness all around the globe.

Spring is just around the corner. The first day of spring, which coincides with the spring equinox, falls on Thursday, March 20, this year.

The spring equinox - also known as vernal equinox - marks the first day of spring in the northern hemisphere, according to the Old Farmer's Almanac. It occurs when the sun is directly above the equator, resulting in nearly equal daylight and night hours.

After the vernal equinox in March, the Northern Hemisphere tilts toward the sun until the June solstice, when the sun begins to migrate back south. At precisely 5:01 a.m. ET on Thursday, the sun's rays fall directly on the equator,
