What is the Spring Equinox?

In the Northern Hemisphere, the March equinox (aka spring equinox or vernal equinox) occurs when the Sun crosses the equator line, heading north in the sky. 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. Equinoxes are the only two times a year that the Sun rises due east and sets due west for all of us on Earth!

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. With the equinox, enjoy the increasing sunlight hours, with earlier dawns and later sunsets.

"Experts say it's a tight race between coronavirus variants and vaccines in the US as air travel hits records and spring break crowds grow. With less than a quarter of all Americans having received at least one dose of a Covid-19 vaccine -- and only about 13% fully vaccinated -- doubling down on safety measures now is what could help curb another surge, experts have repeatedly stressed. 'If we can hang on another month, another six weeks, that's going to make a huge difference.'"
