The vernal equinox falls on March 19 nationwide this year.
Mixing with people may not be the best thing right now, but you can get out and enjoy Spring. It's coming on Thursday, March 19, for nearly all of the Americas.
Perhaps you are mildly surprised to learn that March 19 is the first day of spring.
It is defined as " the time at which the sun crosses the plane of the equator towards the relevant hemisphere, making day and night of equal length.
Indeed, the equinox has historically fallen on one of those dates. This year, the equinox will occur on March 19, which means the earliest first day of spring in more than 100 years.
"We say that this is the earliest equinox of our lives, but we're going to keep saying that", Bob Berman, an astronomer at robotic telescope service Slooh, said.
It's properly called the vernal equinox, that point in time when the Earth's axis isn't tilted either toward or away from the sun.More news: Covid-19 virus remains detectable and stable for hours on surfaces
They don't necessarily line up with each other, because the climate can change (as it is now, causing spring weather to arrive earlier) but the Earth's orbit basically remains the same. This is why day and night appear equal in time.
In fall and winter (for the northern hemisphere), the earth's axis is tilted away from the sun.
What could the weather hold for spring in the U.S.?
If you want to be totally precise, spring equinox 2020 will occur at 3:49 UCT (Coordinated Universal Time) on Friday, March 20. For the USA the 2020 equinox falls on March 19, making it the earliest since 1896.
Equinoxes can, at times, get confused with solstices, which occur in the summer and winter.

One spin of the Earth around its axis is one day. The sun will appear to rise exactly east and set exactly west. "In fact, it's 365.24 [days]".
But, if the year is also evenly divisible by 400, it is then designated a leap year. So every year that is exactly divisible by 4 is a leap year, in which a 29th day is added to February. The leap day turns back the clock on the time of the equinox, almost resetting the approximately six-hour annual leap forward from the previous three years. That's because the Earth's 574,395,530-mile annual orbit of the sun really takes 365.2422 days. But, not ALL leap years.
For people in the Southern Hemisphere, especially in fire-ravaged Australia, it brings the blessed relief of a cooler autumn. A solstice is when the Sun reaches the most southerly or northerly point in the sky, while an equinox is when the Sun passes over Earth's equator. It's unclear if the celebration will happen this year, given the coronavirus outbreak. And, unlike in 1900, we observed a leap day in the year 2000, which turned the clock back even more.
In 2016, spring came on March 19 in the Central and Pacific time zones, but in the Eastern time zone, it fell on March 20.
Will spring always be early?
This is the earliest arrival of spring equinox in 124 years. According to Space.com it's the earliest in 124 years. By the end of the century, the spring equinox will fall on March 19 most years. "We all sort of think that the universe was made for us", she says.
