Spring Equinox

In 2021, the spring equinox occurs on Saturday, March 20. This event marks the astronomical first day of spring in the Northern Hemisphere.
In the Northern Hemisphere, the March equinox (aka spring equinox or vernal equinox) occurs when the Sun crosses the equator line, heading north. This event marks the start of spring in the northern half of the globe. After this date, the Northern Hemisphere begins to be tilted more toward the Sun, resulting in increasing daylight hours and warming temperatures.
The word equinox comes from the Latin words for “equal night”—aequus (equal) and nox (night).
On the equinox, the length of day and night is nearly equal in all parts of the world.
The current seasonal lengths for the Northern Hemisphere are (approximately):
Summer — 93.641 days
Autumn —  89.834 days
Winter —    88.994 days
Spring —    92.771 days
