First Day of Spring: Vernal Equinox

When Does Spring 2017 Begin?

Celebrate the March 2017 equinox with our live telescope show on Monday, March 20! Find out more information—plus, equinox facts and folklore—as we observe the return of sunshine, longer days, and warmer temperatures.


In the Northern Hemisphere, we mark the spring equinox on Monday, March 20, 2017

Live Telescope Show: Celebrating the March Equinox

Starts below on Monday, March 20, 2017, 4:30 PM EDT!

Watch the equinox show below on March 20 to celebrate  the arrival of spring! With our friends at Slooh (and their giant telescopes!), we’ll hear from Almanac editor Janice Stillman, who will discuss this season of rebirth, and Almanac astronomer Bob Berman, who will tell us all about the phenomenon that makes this possible while gazing on live views of our Sun. Plus, witness one of the most amazing sights in the night sky–the magical Northern Lights live from the arctic circle. Slooh will explain this amazing natural spectacle as we watch high-energy particles from the Sun rain down and light up Earth’s upper atmosphere!


When Does Spring Begin?

The March equinox is Monday, March 20, 2017 at 6:29 A.M. EDT.

Astronomically speaking, the equinox falls on March 19 or 20 every year, marking spring’s beginning in the Northern Hemisphere (whereas it announces fall’s arrival in the Southern Hemisphere). The equinox happens at the same moment worldwide, even if our clock times reflect a different time zone.


Meteorologically speaking, in the Northern Hemisphere, the official spring season always begins on March 1 and continues through May 31. Summer begins on June 1; autumn, September 1; and winter, December 1.

  • Weather scientists divide the year into quarters this way to make it easier to compare seasonal and monthly statistics from one year to the next. The meteorological seasons are based on annual temperature cycles rather than on the position of Earth in relation to the Sun, and they more closely follow the Gregorian calendar. Using the dates of the astronomical equinoxes and solstices for the seasons would present a statistical problem because these dates can vary slightly each year.

What is an Equinox?

At the Vernal Equinox, the Sun crosses the celestial equator on its way north along the ecliptic.

All over the world, days and nights are approximately equal. The name equinox comes from Latin words which mean “equal night”—aequus (equal) and nox (night). 

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

On the equinox, Earth’s two hemispheres are receiving the Sun’s rays about equally because 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.)  

Scientific explanation aside, our ancestors were more connected to the Sun than we are today. They observed its pathway across the sky; they tracked how the sunrise, sunset, and daylength changed, using the Sun (and Moon) as a clock and calendar. If you have ever been to Stonehenge or Machu Picchu, you’ll see examples of ancient seasonal markers.

Equinox Facts

Question: Are Day and Night Truly Equal on the Equinox?

Answer: Nope, day and night are not exactly equal at the equinox for two reasons. First, daytime begins the moment any part of the Sun is over the horizon, and it is not over until the last part of the Sun has set. If the Sun were to shrink to a starlike point and we lived in a world without air, the spring and fall equinoxes would truly have ‘equal nights.’

Read about more fun facts in Bob’s post, “March Equinox Oddities.”

Signs of the Equinox in Nature
The vernal equinox signals the beginning of nature’s renewal in the Northern Hemisphere!
  • Worms begin to emerge from the earth. Even the March Moon is called “The Full Worm Moon” for this reason.
  • Notice the arc of the Sun across the sky as it shifts toward the north. Birds are migrating northward, along with the path of the Sun.
  • Speaking of birds, did you know that the increasing sunlight triggers bird song? Cool, eh? Enjoy our Bird Songs page.
  • Trees, shrubs and flowers are sensitive to temperature and daylength, too! Since ancient days, people have used them as indicators of when the weather is right for planting. For example: Blooming crocus are your cue to plant radishes, parsnips and spinach. See more of nature’s signs.
  • Of course, the longer days bring warmer weather! Both we and the animals around us strip off our clothes and heavy coats!
  • Ready, set, plant! March is time to start gardens and sow seeds in many regions. See your personalized Best Planting Dates.

Equinox Folklore

Question: According to folklore, you can stand a raw egg on its end on the equinox. Is this true?

Answer: Folklore or not, this egg trick sounded like a bit of fun to us. One spring, a few minutes before the vernal equinox, several Almanac editors tried this trick. For a full workday, 17 out of 24 eggs stood standing. Three days later, we tried this trick again and found similar results. Perhaps 3 days after the equinox was still too near. Perhaps the equinox has nothing to do with it. Perhaps we just don’t like to take ourselves too seriously! Try this yourself and let us know what happens.


Spring Verse

One swallow does not make a spring.

Bluebirds are a sign of spring; warm weather and gentle south breezes they bring.

In spring, no one thinks of the snow that fell last year.

Don’t say that spring has come until you can put your foot on nine daisies.

Spring-time sweet!
The whole Earth smiles, thy coming to greet.

Look around! Observe! What are the signs of spring in your region? Please share below!

Had snow with some whiteout periods on Saturday evening and Sunday morning for last days of winter. Sunday morning looked nice with all the wet snow clinging to the trees

Thank you Mr D, you have the soul of a poet!
