Spring Equinox Arrives Friday, Marking the Official End of Winter

Spring has sprung! The vernal equinox is here, marking the official start of astronomical spring in the Northern Hemisphere. On Friday, March 20, at 10:46 a.m. ET/7:46 a.m. PT, the sun will cross the celestial equator, bringing nearly equal amounts of daylight and darkness across the globe. It’s a moment of celestial balance—and a perfect excuse to celebrate the changing of the seasons.

What Is the Vernal Equinox?
The word “equinox” comes from the Latin aequus (equal) and nox (night), and it’s exactly what it sounds like: a day when day and night are roughly the same length. This happens twice a year—once in spring (the vernal equinox) and once in fall (the autumnal equinox). The vernal equinox is the tipping point when the Northern Hemisphere begins tilting toward the sun, ushering in longer, warmer days and bidding farewell to winter’s chill.

Why Does It Happen?
Earth spins on an axis tilted at 23.5 degrees. This tilt is why we have seasons. During the vernal equinox, the Earth’s axis is perfectly aligned with its orbit around the sun, so neither hemisphere is leaning toward or away from it. For a brief moment, the sun shines directly over the equator, and the whole planet experiences a near-equal split of day and night.

Vernal Equinox vs. Solstice: What’s the Difference?
While equinoxes mark the transition points between seasons, solstices are the extremes. The summer solstice (around June 21) is the longest day of the year, and the winter solstice (around December 21) is the shortest. Solstices often get more attention because they’re easier to visualize—after all, who doesn’t notice the longest day of the year? But equinoxes are just as significant, quietly signaling the shift in Earth’s journey around the sun.

What the Equinox Looks Like from Space
NASA has captured stunning visuals of Earth’s seasonal transitions, showing how the line between day and night (called the terminator) shifts over the course of a year. Watching the planet cycle through its seasons is a humbling reminder of our place in the cosmos.

Debunking the Egg-Balancing Myth
You may have heard that you can only balance a raw egg on its end during the equinox. This is pure myth. The Earth’s gravitational pull doesn’t magically change on this day. You can balance an egg any day of the year—it just takes a steady hand and a little patience. (I tried it on February 27 and nailed it!)

How to Celebrate the Vernal Equinox
There’s no right or wrong way to mark the occasion. Here are a few ideas:
• Plant some seeds or start a garden—spring is all about new beginnings.
• Take a hike or spend time outdoors to soak up the extra daylight.
• Do a little spring cleaning to refresh your space.
• Host a seasonal feast with friends or family.
• Simply take a moment to appreciate the sun and the Earth’s journey through space.

The vernal equinox is more than just a date on the calendar—it’s a reminder of the beauty and precision of our planet’s dance with the sun. So, whether you’re planting flowers, balancing eggs, or just enjoying the longer days, take a moment to celebrate the arrival of spring.
