Spring Equinox 2024 Ushers in New Season Globally

The equinox marks a period of equal day and night, beginning spring in the Northern Hemisphere and autumn in the Southern Hemisphere.

The spring equinox, marking the official start of spring in the Northern Hemisphere, occurred at 11:06 p.m. EDT on March 19, 2024.
Equinoxes, occurring twice a year, are astronomical events where day and night are nearly equal in length due to Earth's tilt aligning with its orbit.
This year's equinox also signals the beginning of autumn in the Southern Hemisphere, with changes in daylight hours and weather patterns.
Cultural traditions and rituals, such as Nowruz and egg-standing myths, are associated with the equinox, reflecting its significance across various societies.
Despite the arrival of spring, a deep freeze in parts of the U.S. threatens early blooms and challenges the typical warm weather expectations.
