What is March Equinox?
March Equinox, observed every March 20 or 21, marks the astronomical moment when Earth's axis tilts neither toward nor away from the Sun, producing nearly equal day and night across the planet. The event signals the start of astronomical spring in the Northern Hemisphere and autumn in the Southern Hemisphere, and underpins cultural celebrations such as Nowruz, International Day of Happiness, and World Storytelling Day.
How to celebrate
