Wow, first day of Spring. This morning it was warmer out and raining so it made everything smell good. BUT this afternoon the rain was cold, and that turned into lots of water. So that lots of water turned into a flood in the greenhouse. Larry is now pumping with 3 subpumps to get the water to go down around the greenhouse. We have this every spring so maybe this will be it for this season. Here is some facts about this first day of spring. Stay healthy!
In 2020, the spring equinox (also called the March equinox or vernal equinox) occurs on Thursday, March 19, which is earlier than it’s been in over a century! This event marks the astronomical first day of spring in the Northern Hemisphere. Before you try to balance that egg, read this!
The Earliest Spring in More Than 100 Years
If you’re as calendar-obsessed as we are, you may have noticed something odd about this year’s spring equinox date. That’s right—it’s earlier than usual! But that’s a bit of an understatement.
For much of the last century, the spring equinox has occurred on March 20 or 21. This year, however, the equinox happens on the 19th in all U.S. time zones, making it the earliest spring we’ll have seen in our lives (so far). The last time spring arrived this early was in 1896—a whopping 124 years ago!
Naturally, this leads to some important questions, like: Why is the equinox so early this year? Will the date keep shifting earlier and earlier? Will the equinox ever be on March 21 again?
When Is the First Day of Spring?
In the Northern Hemisphere, spring begins with the March equinox, which may occur on March 19, 20, or 21. (In the Southern Hemisphere, the March equinox marks the start of autumn, while the September equinox marks the start of spring.)
What Does “Equinox” Mean, Exactly?
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.
On the equinox, Earth’s two hemispheres receive the Sun’s rays about equally.
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 the Sun 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.
Q: Does Spring Begin on March 1 or on the Equinox?
A: Well, both. The answer depends on your definition of “spring.” Both dates are accurate; they’re just from different perspectives. 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! We won’t see a March 21 equinox 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.
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 its end on the equinox. Is this true?
A: This egg folklore became popular in 1945 following a LIFE article about the spring adage. “The origins of this myth are attributed to stories that the ancient Chinese would create displays of eggs standing on end during the first day of spring,” John Millis, assistant professor of physics and astronomy at Anderson University. “The ancient Chinese celebrated the first day of spring about six weeks earlier than the equinox” so it’s not just on the equinox itself.
As with most folklore, it’s only partly true. It should be balance an egg on its end but also it’s possible to balance an egg on other days, too.
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. (Tip: You’ll probably have better luck balancing the egg if you use a rough surface or an egg that has a bumpy end.)
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?
To us, 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! That is my lesson I want to teach my Sunday School class. LOOK around you and see what nature-science is about.
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.”
Sayings
•Bluebirds are a sign of spring; warm weather and gentle south breezes they bring.
•One swallow does not make a spring.
•In spring, no one thinks of the snow that fell last year.
•When the dandelions bloom early in spring, there will be a short season. When they bloom late, expect a dry summer.
•Don’t say that spring has come until you can put your foot on nine daisies.
