What To Know About The Vernal Equinox.

Spring, or vernal, equinox signals a season change. Every March 19th–21st, the sun crosses the equator and day and night are about equal in duration (thus "equinox" from Latin for "equal night"). This astronomical event marks the start of spring in the Northern Hemisphere, with higher temperatures, longer sunshine, and plant and animal life. In the Southern Hemisphere, autumn begins. Many cultures celebrate the vernal equinox to welcome spring.

The Southern Hemisphere March equinox provides later sunrises, earlier sunsets, chillier air, and dropping leaves. On Tuesday, the Northern Hemisphere will see earlier sunrises, later sunsets, gentler breezes, and blossoming flowers.
