AS THE days begin to get slightly longer, many of us will be wondering when we can finally call it spring.
March 20 marks the Spring Equinox – but when is winter officially finished and is it the same thing as the Vernal Equinox? Here’s the lowdown on this somewhat confusing time of year…
When is the Spring Equinox?
Good news for those counting down the days until warmer weather – the 2017 spring equinox is now here, taking place at 10.28am GMT on March 20.
This is the time when the sun passes the celestial equator and days become longer – no more going to work in pitch darkness.
For some March 20 marks the first official day of spring – but meteorologists argue that it’s actually March 1.
What is the Vernal Equinox?
The Vernal Equinox is another name given to the Spring Equinox and labels the March Equinox is the Northern Hemisphere.
In the Southern Hemisphere the March Equinox is called the Autumnal Equinox.
In September the equinoxes are labelled vice versa – the Northern Hemisphere experiencing an Autumnal Equinox and the Southern Hemisphere having their Vernal Equinox.
The equinox marks the moment the Sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator.
It is at this time that the Northern Hemisphere marks the first day of astronomical spring.
When date does it fall on in March?
The 2017 Vernal Equinox, is the same thing as the Spring Equinox and falls on March 20.
