First Day Of Spring 2019: The Spring Equinox

In 2019, spring equinox (also called the March equinox or vernal equinox) falls on Wednesday, March 20. This event marks the astronomical first day of spring in the Northern Hemisphere. Before you try to balance that egg, read this!

A FULL MOON ON THE SPRING EQUINOX!

The last time the Full Worm Moon happened less than one day of the March equinox was 19 years ago, in 2000, and the next time will be 11 years from now, in 2030.

But that’s not all: March’s full Moon will also be a supermoon, meaning that it will be slightly larger than most of the other full Moons this year.

What an extra-bright way to greet spring!!

See Bob Berman’s new article, Full Moon on the Spring Equinox!

WHAT DOES THE EQUINOX MEAN?

The word equinox comes from the Latin words for “equal night”—aequus (equal) and nox (night).

On the equinox, the length of day and night is nearly equal in all parts of the world.

With the equinox, enjoy the increasing sunlight hours, with earlier dawns and later sunsets. See your personalized Sun rise and set calculator.

WHAT HAPPENS ON THE MARCH EQUINOX?

On the March Equinox, the Sun crosses the celestial equator from south to north. It’s called the “celestial equator”  because it’s an imaginary line in the sky above the Earth’s equator.

If you were standing on the equator, the Sun would pass directly overhead on its way north.

Equinoxes are the only two times a year that Sun only rises due east and sets due west for all of us on Earth!

While the Sun passes overhead, the tilt of the Earth is zero relative to the Sun, which means that Earth’s axis neither points toward nor away from the Sun. (Note, however, that the Earth never orbits upright, but is always tilted on its axis by about 23.5 degrees.)

After the Spring equinox, the Northern Hemisphere tilts toward the Sun, which is why we start to get longer, sunnier days
