Millions of people across the Midwest and Central America felt the cold of another winter storm just last week, but Americans can look forward to the first day of spring very soon.
When is the first day of spring?
Wednesday, March 20, 2019 at. 5:58 pm ET, spring equinox, also known as vernal equinox, will bring the first day of spring to the northern hemisphere.
What is the difference between an equinox and a solstice?
Twice a year equinox occurs in the fall (September 21) and in the spring (March 19, 20 or 21 it varies), which causes a seasonal change. The word "equinox" means "just night", why it happens twice a year when day and night are equal, every 12 hours.
The spring equinox occurs when the sun crosses the celestial equator from south to north, according to the old farmer's almanac. The heavenly equator is an imaginary line over the earth's equator. However, this equinox marks the start of different seasons in both hemispheres. In the southern hemisphere, March announces the equinox start of the fall.
Every day since the winter sunshine in December has been a little longer than the last one, in preparation for the spring rest, which "marks the turning point when daylight begins to gain beyond the dark," notes the farmer's almanac.
Equinox is not the only marker for seasonal changes. Every year there are also two sunbeds that mean a change of season. The word "solstice" refers to the moment when the sun is at either the northernmost or southernmost point.
Solstice marks the start of the winter and summer season (in June and December). In the northern hemisphere, summer solstice is the longest day of the year, and winter solstice is the shortest.
Can you really balance an egg on the equinox?
Some say you can balance a raw egg on its end under the vernal equinox. This bit of folklore became popular in 1945, after LIFE published an article on the balance, but the myth has been debunked as only partial sand, according to AccuWeather.
Facts control website Snope's reports, "The same result can also be achieved every other day of the year."
So yes it is possible to balance an egg on the equinox, but it is also possible to balance an egg on other days. In fact, several calendar editors tried the trick one spring, and 17 out of 24 eggs were standing, they said. After trying the trick again three days after the equinox, the editors found similar results.
Supermoon on equinox
This year's vernal equinox will be something special, as the full moon in March – also the final supermoon in 2019 – falls on the same day. According to the old farmer's almanac, the last time full moon and spring vinox had occurred the same day on March 20, 1981. And because this full moon is a supermoon, it will also appear brighter and larger than normal.
But this moon is also particularly suitable for the beginning of spring, as it is called Full Worm Moon. According to the almanac, the moon got its name from Native Americans called the full moons to track the seasons. In March, as spring comes, the soil softens enough for worms to come out, signals a new season and with the heat.
The best time to see the moon is after the moon rises, which varies from state to state. In New York, it is 9:42 pm local time. On the other side of the country in Los Angeles, this is 6:42 pm This is the last supermoon until March 9, 2020.
