Overview

• The spring equinox in 2025 will occur on Thursday, March 20, at precisely 09:01 UTC, marking the start of spring in the Northern Hemisphere and fall in the Southern Hemisphere.
• Equinoxes occur when the Earth's equator aligns with the sun, resulting in nearly equal amounts of daylight and darkness across the globe.
• In the Northern Hemisphere, the equinox signals longer days and warming temperatures as the region tilts toward the sun.
• The event is best appreciated at sunrise or sunset, when the sun rises due east and sets due west, a unique occurrence on equinox days.
• The next major astronomical event will be the summer solstice on June 20, 2025, marking the longest day of the year in the Northern Hemisphere.
