The spring equinox (also called the vernal equinox) marks the astronomical start of spring in the Northern Hemisphere. This countdown tool below tracks the days, hours, minutes, and seconds until the next Spring equinox.
When is the spring equinox?
The spring equinox typically falls on March 19th, 20th, or 21st, depending on the year and your timezone. At the equinox, day and night are approximately equal length everywhere on Earth - in fact, the word "equinox" comes from Latin aequus (equal) and nox (night).

The astronomy of the spring equinox
At the spring equinox, the Sun crosses the celestial equator heading northward. Check out my sun angle calculator to see how the sun's position changes throughout the year.
