Welcome to Spring 2023.
The March Equinox happened last Monday, March 20, at 5:24 P.M. EDT. On the March equinox, the Northern Hemisphere and Southern Hemisphere receive roughly equal amounts of sunlight; neither hemisphere is tilted more toward or away from the Sun than the other.
Interesting Fact
Equinoxes are the only two times each 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.)
Folklore
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 practice. “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,” according to John Millis, assistant professor of physics and astronomy at Anderson University in South Carolina. “The ancient Chinese celebrated the first day of spring about six weeks earlier than the equinox”—not just on the equinox itself.
As with most folklore, it’s only partly true. You should be able to balance an egg on its end on the equinox, but it’s possible to balance an egg on other days, too!
Try It
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 on end. Three days later, we tried this trick again and found similar results. Perhaps three 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!
