The spring equinox, also known as the vernal equinox, typically occurs on March 20, 21, or 22 in the Northern Hemisphere.

In 2025, it happens to be today, March 20! This is the moment when the Earth’s axis is tilted neither toward nor away from the Sun, resulting in nearly equal amounts of daylight and darkness across the globe—about 12 hours of each.

It marks the official start of spring in the Northern Hemisphere (and autumn in the Southern Hemisphere). Astronomically, it’s when the Sun crosses the celestial equator moving northward. Culturally, it’s often associated with renewal, growth, and balance—think blooming flowers and longer days ahead.

Historically, many societies, like the ancient Persians with Nowruz or the Mayans with their equinox-aligned pyramids, celebrated it as a time of harmony and new beginnings.
