Date and Time of March Equinox/Spring Equinox

As per the Old Farmers' Almanac, people living in the Northern Hemisphere, will welcome the first day of spring at 11.50 PM ET on March 19, Thursday. It is the point when both the hemispheres of the planet will receive the same amount of daylight. The equinox marks the official start of spring, regardless of the weather outside.

What is the Equinox?

An equinox is the instant of time when the plane of Earth's equator passes through the center of the Sun. So the Sun is directly above the equator. The word 'Equinox' is derived from Latin aequus (equal) and nox (night). It means there is an equal daytime and nighttime on all of the planet. It is also called as Vernal Equinox. It occurs twice during a year, once in March called the Vernal or Spring Equinox and once in September. The usual dates are 20-21 March and 21-23 September. The dates vary depending on the Earth's rotation and leap years. Why You Should Drink More Water During Spring Equinox?

From this year, the equinox will get earlier and earlier every four years, with even parts of Europe and Africa experiencing a March 19 equinox in this century. The elliptical orbit of the planet changes in its orientation and thus the earth's axis points in a different direction. The gravitational pull from other planets also affects the location of earth in the orbit.

The leap year of 2020 is another reason, why the March Equinox will occur about 18 hours earlier than the date last year. Thus for all timezones in the US, it will be pushed to March 19. The calculation will go on every 4 years, culminating in early equinoxes.
