The Equal Night: Ancient Traditions and Modern Facts about the Vernal Equinox

This Friday, March 20, 2026, at exactly 10:33 AM (Eastern Time), Spring will officially arrive in the Northern Hemisphere. This moment is known as the Vernal Equinox—derived from the Latin words ver (spring) and equinox (equal night).

The Science of Balance

During the equinox, the Earth’s axis is tilted neither toward nor away from the sun. This means that nearly everywhere on Earth, day and night are almost exactly 12 hours each. From this point forward, our days will continue to grow longer until the Summer Solstice in June.

The Great Egg Myth

You may have heard the old folklore that the equinox is the only day of the year you can balance a raw egg on its end. While it’s a fun classroom experiment, the truth is a bit more mundane: you can balance an egg on its end any day of the year if you have enough patience and a steady hand! The “gravitational pull” of the equinox has nothing to do with it.

Global Celebrations

• Chichen Itza, Mexico: At the Kukulcan pyramid, the setting sun creates a shadow that looks like a snake slithering down the stairs.


• Nowruz: Millions of people in Central Asia and the Middle East celebrate the “Persian New Year” on the equinox, symbolizing rebirth and the victory over winter.

Whether you’re planting seeds or just enjoying the extra sunlight, the start of Spring is a universal symbol of hope and a fresh start. Happy Spring!
