Autumnal Equinox – Sunday

Sunday and today marks the autumnal equinox, the time when the day light and dark of the night are exactly equal.

Why is it called an Equinox?

On the equinox, night and day are nearly exactly the same length – 12 hours – all over the world. This is the reason it’s called an “equinox”, derived from Latin, meaning “equal night”/

The September equinox occurs the moment the sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from north to south.

This happens either on September 22, 23, or 24 every year. On any other day of the year, the Earth’s axis tilts a little away from or towards the Sun. But on the two equinoxes, the Earth’s axis tilts neither away from nor towards the Sun.

So a happy Equinox to everyone !
