When does spring officially begin?

Astronomical spring began at 11:33 a.m. ET on Sunday, March 20, 2022, in the Northern Hemisphere, according to AccuWeather. This time also marked the beginning of autumn in the Southern Hemisphere.

What is the vernal equinox?

"Equinox" derived from the Latin word meaning "equal night," according to AccuWeather.

During an equinox, the Earth is positioned with both its axis and its orbit perpendicular to the sun, allowing the sun's rays to aim directly at our planet's equator. As a result, both day and night are 12 hours long around the globe.

The vernal, or spring, equinox was the first of two for the year: 2022's autumnal, or fall, equinox will occur at 9:04 p.m. ET on Thursday, Sept. 22.

Conversely, solstices mark the most drastic time differences between night and day. In 2022, the summer solstice, the longest day of the year in the Northern Hemisphere, happens at 5:14 a.m. ET on Tuesday, June 21. The top half of the world will experience the shortest day of 2022 during the winter solstice at 4:48 p.m. ET on Wednesday, Dec. 21.
