As the chill of winter fades, signs of spring emerge. This seasonal transition occurs when the spring equinox takes place. In 2024, spring will officially start on March 20 at 10:46 a.m. ET. This marks the moment when the sun’s rays strike the equator directly.
Understanding the Spring Equinox
The equinox signifies the end of astronomical winter and welcomes the arrival of spring. At this point, day and night are nearly equal in duration, with both lasting approximately 12 hours. Following the equinox, daylight hours will gradually increase until the onset of summer.
Key Details About the Spring Equinox
