The 2020 vernal equinox will bring the earliest spring to the United States in 124 years.
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. It occurs about March 21 in the N hemisphere”.
Except today it is not – in fact, March 19th is the earliest vernal equinox in the last 124 years in the US.
The exact moment of the equinox will be tonight at 11:49 p.m. EDT.
The website Space.com writes, “At that time, the Earth will reach the point in its orbit where its axis isn’t tilted toward or away from the sun. Thus, the sun will then be directly over a specific point on the Earth’s equator moving northward. On the sky, it’s where the ecliptic and celestial equator cross each other.”
