Celebrate the Vernal Equinox and the Start of Spring
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.
Full Moon:
For the first time in nearly 40 years, the spring equinox will occur on the same day as March’s Full Worm Moon. The last time that these two events landed on the same date was on March 20, 1981, though they did come close again in March 2000, separated by a span of only four hours. But that’s not all: March’s full Moon will also be a supermoon, meaning that it will be slightly larger and brighter than most of the other full Moons this year.
What Does 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.
Q: Is the First Day of Spring Always March 20th?
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 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! 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.
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: How Do You Celebrate the Vernal Equinox?
A: 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?
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.
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.
