Spring Equinox 2019: The First Day of Spring

March Equinox Date | Vernal Equinox

By The Old Farmer's Almanac
Welcome Spring Equinox

The spring equinox (also called the March equinox or vernal equinox) falls on Wednesday, March 20, 2019, at 5:58 P.M. EDT. This event marks the astronomical first day of spring in the Northern Hemisphere. Enjoy our spring equinox facts, folklore, photos, and more!

When is the First Day of Spring?

Spring begins with the vernal equinox, which always occurs on March 19, 20, or 21.

What Does the March 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 Norther Hemisphere tilts toward the Sun, which is why we start to get longer, sunnier days

Spring Equinox FAQs

Q: Is The First Day of Spring Always March 20?

A: No, it’s not always March 20. And your answer also depends on your definition of the “first day of spring.”  Both are accurate; they’re just a different perspective. We’ll explain …

Astronomically speaking, the first day of spring is marked by the spring equinox, which falls on March 19, 20, or 21 every year. The equinox happens at the same moment worldwide, though our clock times reflect a different time zone. And, as mentioned above, this date only signals spring’s beginning in the Northern Hemisphere; it announces fall’s arrival in the Southern Hemisphere.

Interestingly, due to time zone differences, there isn’t a March 21 equinox in mainland U.S. during the entire 21st century! Plus, we won’t see a March 21 in the world again until 2101.

Meteorologically speaking, the official first day of spring is March 1 (and the last is May 31). Weather scientists divide the year into quarters 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, as these dates can vary slightly each year.

Did you know that daffodils are one of March’s Birth Flowers?

Q: Are Day and Night Equal on the Equinox?

A: No, but they are close to equal. In reality, 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.’

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

A: Folklore or not, this egg trick sounded like 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.

Q: Which Day Has the Most Sunlight in North America?

A:  The Summer or June Solstice is called the “longest” day of the year! The date of the longest day actually varies between June 20 and June 22, depending on the year, and the local time zone. By “longest day,” we mean the day that gets the most daylight (versus darkness).  See our Summer Solstice page.

How Do You Celebrate the Vernal Equinox?

The vernal equinox signals new beginnings and nature’s renewal in the Northern Hemisphere! Many cultures celebrate spring festivals, like Easter and Passover.

Observe nature around you!

  • Worms begin to emerge from the earth. In fact, the March Full 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 is what triggers birds to sing? Cool, eh? Enjoy our Bird Songs page.
  • Trees, shrubs, and flowers are sensitive to temperature and day-length, 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 the Best Planting Dates according to your local frost dates.

Ancient Equinox Traditions: The Snake of Sunlight

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 day length changed, using the Sun (and Moon) as a clock and calendar.

There are many ancient sites that mark the equinoxes (and solstices). One of the most famous ancient Spring equinox celebrations was at Chichen Itza in Mexico. The Mayans built a huge pyramid around the year A.D. 1000.  The play of the Sun’s light on it signals the beginning of the seasons. On the spring equinox, it looks like a huge snake is slithering down the steps. Mayans called this day “the return of the Sun serpent.”

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.

Eggs upright! - all across

Eggs upright! - all across America! I put all 12 up, 3 of them standing on my cutting board, the others on the electric burner os my stove inspired by the almanac pic. 2 friends sent pics of theirs on flat shiny surfaces, another friend on her stove, my mom's in the corner of the tile, another on the tile floor. I also held it straight up & down in my hand. I could really feel it's energy pulling it into perfect balance. Don't give up! I couldn't quit once I got started. Where do I post all the pictures?

To address the misconception,

To address the misconception, you can stand an egg on its head any time of the year. The seasons have absolutely nothing to do with it at all. It just depends on how flat your surface is how nicely shaped the egg is.

Our broom stands up in our

Our broom stands up in our broom closet until someone pulls it out and uses it. On the other hand, what came first, the spring equinox or the egg?

i stood an egg up and it

i stood an egg up and it stayed for a lil while then fell over. the broom works great tho. the eggs should balance as so when the equinox comes closer as the force would be stronger. so if you havent had any luck just be a lil patient.

I have never in my life been

I have never in my life been able to balance anything and as the above post states... The broom and the egg are still standing beside me as I st here at the bar. I am in the Panhandle of Florida and its not March 20th however the objects still stand. I will continue to try this and see what happens! FIRM BELIEVER!!!

That is awesome! my son is

That is awesome! my son is trying to get our broom to stand on end now, lol. We are testing it here in s.e. oklahoma. Will let you know the outcome later today.

My 12 yr old daughter and I

My 12 yr old daughter and I tried the broom and egg "trick" earlier tonight after all the buzz posted on FB. Well...it worked!! And they are BOTH still standing in my litchen as I type! I've tried this before today and it never worked. I'm a believer!! :-)

I live on hour north of KC

I live on hour north of KC Missouri. My fiance saw all the posts about the broom and egg so he tried it...and our broom and egg have been standing on end for the past hour...also my broom is a slanted one to sweep out corners..so there is no way it could ever do this on it's own..it's top heavy...creepy...I have friends in NY state that tried it but no luck..too bad its really neat to see. :)

My friend asked me what all

My friend asked me what all the pictures in Facebook were about standing brooms, and I said I don't know. We tried the broom outside, and it worked. We tried the eggs inside and the broom inside and it worked. Anyone feeling the magic?

My friends broom is standing

My friends broom is standing in her bathroom. And has been for hours but my broom wont and niether did the eggs that I tried to stand on end. Hmm wierd

does not need to be a new

does not need to be a new perfect broom. I've done it with my decade old beaten up broom.

please explain to me how to

please explain to me how to get the broom to balance on its own because im going to the store just to buy a brand new broom to try this because it seems very interesting.

I stood 2 brooms up today,

I stood 2 brooms up today, Neither were new, both were angled brooms, one stood for almost 3 hours and I had to leave and couldn't leave it standing at work, the other stood until the baby knocked it down. And could easily be stood back up. IDK Y but it works.

I don't understand how the

I don't understand how the tilt of the earth can make an egg stand vertically. Perhaps I'm missing something...I understand that the egg in the photo is standing because of the crease of whatever it's on, but I still think that this may actually be possible (despite the fact that I haven't tried it yet. I just don't fully understand HOW. But maybe we don't need to understand...

Well, it's really just

Well, it's really just folklore. The premise is that an egg will balance on the vernal and autumnal equinox because the Sun is crossing the equator and that having the center of the Earth aligned with the gravitational pull of the Sun makes it easier to balance any object. It may be that you can balance eggs any day of the year. You may want to try it and pick a day!

I figured it might have

I figured it might have something to do with the equator, but I was never really sure. I guess I'll just have to try it some time.

I never could understand that

I never could understand that folklore myself. Gravity is generated by the spin of the earth and not the pull of the sun. If the Sun's pull influenced the ability of the egg to stand up, then it would only hold at the equator where it is perpendicular. In other parts of the world as you move up the curvature, the sun's pull would move from perpendicular.

Actually, gravity is

Actually, gravity is generated from the center of any reasonably large body (Sun, Earth, moon, etc.) When the earth spins, it causes centripedal force which causes winds, among other things

Yes! And the interaction of

Yes! And the interaction of the Sun and Moon causes tides. Thus a perpendicular egg would be due to tidal forces, among others.

As I learned it back in 1968

As I learned it back in 1968 in Physics 101: Gravity is a mutual attraction generated by both the earths mass and the corresponding mass of the object. Centripetal force is generated by the spin of the earth as it acts upon the mass of the object.
BTW gravity's attraction between 2 objects across space such as the sun and the earth (and the egg as well) also is a contributing factor when attempting to account for all forces acting upon the egg.
Just sayin - - -

The sun and moon both affect

The sun and moon both affect the gravity on earth. That is what influences the tidal cycles of spring to neap and back, as the sun and moon position themselves in alignment or on opposite sides of the earth. Theoretically then, the egg / broom / whatever story should be possible more often then only at the spring equinox (which happens twice annually).

So u r saying by that u

So u r saying by that u should be able to even balance 3 golf balls on top of each other, correct. About 12that of us tried that yesterday, 03/12/2012 and none were successful, so how is it that u say u can balance things easier right now? And in response to those asking about early spring...we have had an even milder winter than usual here in Knoxville this year. 70 degree weather in February is extremely nice!!!

I have 2 brooms that have

I have 2 brooms that have been standing on their own in our kitchen since last night!

Actually, one of the tests of

Actually, one of the tests of a good quality hand made broom is that it will stand up (that is - stay standing) on its own. Learned this from a fellow at a pioneer village type tourist spot.

This standing of the broom or

This standing of the broom or the egg... it is NOTHING. Any day of the year, my wife can make her broom for indefinite periods of time, to stand on its own, or flip, or even HOVER!; AND it uses no gasoline, but still takes her anywhere she wants to go!!!

To loveisinvein: Whats does

To loveisinvein:
Whats does a broom standing on end on March 01 have to do with vernal equinox lore? The vernal equinox is March 20 according to the farmers' almanac , although the actual "equal" night/ day is March 16-17. My grandpa always said to plant seedlings outdoors on st. patricks day.

In addition to the egg, you

In addition to the egg, you can also stand a broom up by itself... I must admit that it is rather freaky, but also awesome at the same time! Mine has been free standing for the past hour.

I tried both egg and broom to

I tried both egg and broom to zero sucess. Maybe a new broom would but as for the egg.........Just ain't happenin...........

You need a new broom. Only

You need a new broom. Only new brooms sweep clean.

If you have a broom that will

If you have a broom that will stand then it will stand any day of the year. The bristles disperse the weight of the broom evenly (if done correctly) and it allows the broom to balance. The suns position in the sky has no bearing on the broom. If it did this would only work on the equator at high noon.
