Twice each year, Earth reaches a moment of near-perfect balance. During the March equinox, sunlight falls evenly across the planet, bringing almost equal day and night to both hemispheres. For centuries this astronomical event has fascinated scientists, guided farmers, inspired festivals, and shaped calendars. The equinox is not just a seasonal turning point—it’s a reminder of how Earth’s orbit and tilt choreograph the rhythms of life on our planet.

The equinox is famous for bringing roughly equal daylight and darkness to most places on Earth. While not perfectly exact due to atmospheric refraction and the Sun’s size, the balance is close enough that day and night appear nearly the same length across the globe.
