March equinox 2020: When is March equinox? What is Spring Equinox?
The March equinox happens on March 20 in 2020. The March equinox or Northward equinox is the equinox on the Earth when the subsolar point seems to leave the Southern Hemisphere and cross the celestial equator, traveling northward as observed from Earth. The March equinox is known as the vernal equinox (spring equinox) in the Northern Hemisphere and as the autumnal equinox in the Southern.
The March equinox might be taken to mark the start of spring and the finish of winter in the Northern Hemisphere yet denotes the start of autumn and the finish of summer in the Southern Hemisphere.
When is March equinox?
This year, the March Equinox will occur on Friday, March 20.
In 2020, the spring equinox occurs at 11:50 p.m. Eastern Daylight Time. By squeezing in barely in time on the East Coast, that implies it will be the first time in 124 years the equinox falls on March 19 for all U.S. time zones.
The Met Office clarified: “Spring in the meteorological calendar is the season beginning in March and ending in May.
“Astronomically, spring typically starts on the day of the vernal (or spring) equinox which falls around the 20 March in the Northern Hemisphere.
“The equinox refers to when the sun’s path crosses the equator and the day and night are of equal lengths lasting around 12 hours each.”
What is Spring Equinox?
In the Northern Hemisphere, the minute in time when the Sun stands straightforwardly over the equator while crossing from the south toward the north is called vernal equinox (otherwise called spring equinox, March equinox or northward equinox). It is the moment winter closures and spring starts in the Northern Hemisphere (where almost 90% of the total populace live). For the Southern Hemisphere, it is the autumnal equinox (fall equinox) as it is the moment summer closures and autumn (fall) starts.
“Equinox” is gotten from Latin and signifies “equal night”. Upon the arrival of an equinox, day and night are of approximately equivalent length everywhere throughout the world, as the Earth’s rotational axis is neither tilted away from nor towards the Sun. At all different times, the length of day and night will be different.
Why does the Spring Equinox happen?
The equinox happens as a result of the tilt of the Earth according to the Sun. This is the thing that causes the seasons.
The Earth’s tilt is 23.5 degrees comparative with the plane of its orbit and implies that, albeit one revolution of the planet takes 24 hours, it’s different relying upon the season.
Throughout the summer-time, the Northern Hemisphere is tilted towards the Sun, so we get longer days as more light falls on this part of the planet.
In the winter-time, it’s the Southern Hemisphere that gets most of the light.
On the spring equinox, the Earth hits the turning point in its orbit where neither the North or the South poles are tilted towards the sun.
Subsequently, the Sun spends a generally equivalent amount of time above and below the horizon at every location on the Earth, so night and day are about a similar length.
The word equinox is Latin for “equal night”.
Meteorologists use it as the official turning point in the seasons because, even though it can change from year to year, it allows the most exact record-keeping.
