In 2020, The spring equinox (also called the March Equinox or vernal equinox) falls next Thursday, March 19th, which is earlier than it's been for over a century! This event marks the astronomical first day of spring in the Northern Hemisphere.
For much of the last century, the spring equinox has occurred on March 20 or 21. This year, however, the equinox happens on the 19th, making it the earliest spring we'll have seen in our lives (so far). The last time spring arrived this early was in 1896 - a whopping 124 years ago.
