On March 20, 2025, Earth experiences the vernal equinox in the Northern Hemisphere and the autumnal equinox in the Southern Hemisphere.
What Happens on the Equinox?
- Equal Day & Night: The sun appears directly above the Equator at noon, creating approximately 12 hours of daylight & 12 hours of darkness worldwide.
- Seasonal Shift:
- Northern Hemisphere → Spring Begins (Longer days ahead!)
- Southern Hemisphere → Autumn Begins (Shorter days incoming!)
- Why Does This Happen? – The Earth’s axis is neither tilted toward nor away from the sun, allowing both hemispheres to receive equal sunlight.
About Equinox
- The word “equinox” comes from the Latin words aequus (equal) and nox (night).
- On all other days, Earth’s tilt causes unequal day & night lengths in different parts of the world.
- Ancient cultures used equinoxes to mark the changing seasons, influencing calendars and festivals.
