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.’

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

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.

THIS IS THE BEGINNING OF

THIS IS THE BEGINNING OF SPRING: "Imbolc or Imbolg (pronounced i-MOLK or i-MOLG ), also called (Saint) Brighid’s Day (Irish: Lá Fhéile Bríde, Scottish Gaelic: Là Fhèill Brìghde, Manx: Laa’l Breeshey), is a Gaelic festival marking the beginning of spring. Most commonly it is held on 31 January–1 February, or halfway between the winter solstice and the spring equinox." THINK YOU MIGHT BE WILLING TO SET YOUR WEBSITE ARIGHT?

Hmmm, you contradict

Hmmm, you contradict yourself. You state that the beginning of spring is the Gaelic festival, but then state it's halfway between the winter solstice and the SPRING solstice. The solstice marks the actual start of spring not a festival.

Actually, no, I believe they

Actually, no, I believe they said it was halfway between the equinox and the solstice, not between the solstices. For people who follow the Celtic religions, Imbolc is one of 4 original yearly holidays, the others being Beltaine (May 1) Lughnasad (a sun/harvest festival) Aug 1 and Samhain (Halloween), Oct 31/Nov 1. This is considered by many to be Celtic New Year, instead of January 1. Notice there is one festival every 3 months, or quarterly. (Some of the other adopted Pagan holidays such as Yule, Ostara (Easter) and so on...were of Germanic/Nordic origin, however, some people celebrate them as well, but they weren't originally followed by the Celtic peoples. Sign me- student of comparative religions & mythologies Peace

The Celtic New Year is

The Celtic New Year is actually Samhain, better known now as Hallowe'en or the evening before All Hallows. Samhain marks the death of Summer and the birth of Winter, as the Celts divided their annual cycle into halves as well as quarters and cross-quarters, the two halves being Summer and Winter.

As for Imbolc, it marks the first stirrings of Spring, but remains a seasonal Winter festival (the last one prior to the Spring Equinox). Ostara or the Vernal/Spring Equinox is the first Spring festival, and May Day or Beltane is the first day of the Summer season, with the Summer Solstice being the middle or high point of the Summertime, when the Suns' energy reaches its' zenith and begins waning, with the days growing shorter and the trek moving back into Autumn, toward Winter.

To clarify this, one could view Imbolc as either a Winter or Spring festival, or both. It takes place when the Winter is still on us, but it marks the first stages of Spring, based upon the agrarian events taking place around that time, such as the lambing season, preparing for the Spring ploughing, etc.

And before I get chastised again, these are, indeed, the astronomical designations of the seasons, marked by the position of the Earth in its' annual cyclical orbit in relation to the Sun... and yes, it is scientific. The local weather is another matter entirely, and is not necessarily effected by the astronomical progression of Earth and Sun.

Nicely elaborated upon!

Nicely elaborated upon! Thankyou. Well said. As someone who's lived in both SoCalifornia (where there are practically no visible signs of season change) and moving to Colorado, where the latest snow of the year I recall was a blizzard on Memorial Day, I definitely prefer the wild variations on the latter. But that's just because I like extreme weather.

So do I, though here in

So do I, though here in Kentucky the Summer can be brutally hot... that part I'm not too fond of at all, but I do like the change of seasons and watching the garden as the changes effect it year to year. We got a decent Winter here for once in a long time (though it was late), so I'm hoping the soil will do better than it has in a while. Hope you have a great Spring and a wonderful year!

It's been anything but a mild

It's been anything but a mild winter here in central New England. January was typically very cold, and since the second week of February, we've had about 60 inches of snow. (with maybe 6-12 more inches tomorrow night). But as I write this, I calculate there's about sixty hours left of winter. And I've always said it doesn't matter half as much what it's doing outside as what the calendar says. And the calendar says it's Spring on Wednesday. Ah, Spring. Yeah, baby!

I'm living in Western KY next

I'm living in Western KY next to the Ohio River. My jonquils have been blooming for two weeks. The last two winters here have been mild and we are now designated zone 7 by the "experts" who determine these things. We were zone 6b. Global warming? Another debatable issue. I am 74 and I know the weather patterns are greatly different than they were in my youth so something IS happening on this earth.

We're in north central

We're in north central Kentucky (not far from Louisville), and I can attest to the fact that this is the first Winter that's been even remotely normal for at least two decades, based on the last fifty years or so. It's been a very welcome thing, considering that the soil quality has been steadily deteriorating, and the insect population increasing to a very noticable extent. My hope is that (a) having actually HAD Winter this year (though it started late), it will help improve the soil and kill off some of the insects and (b) that the global warming we've all witnessed is, indeed, a cyclical phenomenon rather than one caused by human recklessness.

I don't doubt that a lot of our practises are not good for the planet, especially the massive deforestation we're responsible for. But from what I've read, there have been times in history where the carbon levels have been much higher than they are now, and things went back to a colder trend. The most important thing is balance. It seems many want to take the position that warm is good and cold is bad. Nothing could be further from the truth. Each is essential in its' season, which is why the richest portion of the farm belt lies in areas which are balanced by Summer and Winter.

Crazy so many places are mild

Crazy so many places are mild and getting ready for spring I live just about an hr east of Pittsburgh and we are below average lows. We barely make it past 35 or so. Last weekend we had 2 days that were almost 50 but then right back to teens and low 20s in the am. So count your blessings guys

Greetings to all my American

Greetings to all my American cousins, from the social democratic paradise that exists on your Far North (i.e. Canada). Toronto, Ontario also had a mild winter with perhaps 1/10th the snow of New York City. I prefer the brisk, sunny days of March to the high heat and humidity of July. I beg the gods of Climate Change to keep our summer on the cool side. Warm regards (but not too warm).

Warm regards, Cousins and

Warm regards, Cousins and Cousines, our French relatives are still there! I marvel that so many folks like living so far north, yet how bizarre our winter has been when we usually get over 300 days of sunshine. In some places we were colder this year, fifteen below in Denver, more with windchill. Yesterday, 70 and the crocus finally bloom a little, many of our migrating birds have disappeared, so they must be winging their way back to you; it must be warmer right around the corner.

The good old Earth, each year

The good old Earth, each year it renews its promise to bring its mildness and sweetness and life to us. The dear Earth.

North TX has experienced a

North TX has experienced a 'normal' winter, seasonal snow, sleet and rain but for me, has been more uncomfortable than usual (debates are whether more or less humidity affects one's tolerence to cold.) We've had some warm days tho' with robins arriving, black birds migrating, and several pairs of cardinals returning and nesting, signaling spring is closer for our part of the state. Experts recommending holding off applying fertilizer since ground hasn't warmed up for growing because of fewer sunny winter days.

In my neck of the woods, you

In my neck of the woods, you know that Spring is here when you see your first chipmunk. Last year it was March 17. Hope it's sooner than that this year!

Around here, in North Texas

Around here, in North Texas near the panhandle, I know it's nearly spring when my grape hyacinths show green leaves and start to send up shoots. We've got green but no shoots just yet. Might get another cold snap or two this year. Or so say the hyacinths, lol.

The 16th of March has a day length of 11:59 hours. This is about as close as you can get to equal day/night length and should rightly be called the vernal equinox. I am wondering if the 20th is just a traditional date for simplicity's sake and is really not the scientific equinox!

I chuckled at the photo of

I chuckled at the photo of the American robin in signs of spring. Most American robins do not migrate very far; they simply shift locally due to a change in their feeding habits (from worms in your yards to the berries on trees). If you want to find them in the dead of winter you have only to go so far as the deep woods nearby.

For birds, a better sign of impending spring in most locations is to visit your local marsh and see if there are Red-winged Blackbirds. They're truly long-distance migratory birds that are easily identifiable by sight and song.

To, the robin is still a

To, the robin is still a great symbol of spring. Though some varieties will spend the whole winter in their breeding range, many do not. And those that stay tend to roost up in trees and not spend much time in the yard. So, when you see them tugging at worms in your yard, THAT is a symbol of spring.
