Spring (Vernal) Equinox 2024

In 2024, the first day of spring is Tuesday, March 19.

On the vernal equinox (March 19, 2024), the Sun will cross the celestial equator—an imaginary line in the sky above Earth’s equator—from south to north. This instant marks the March equinox everywhere on Earth. If you live in the Northern Hemisphere, it’s the spring equinox; in the Southern Hemisphere, it’s the autumn equinox.
