What happens during equinox?

The March equinox, also known as the Autumn equinox, marks the transition from summer to autumn in the southern hemisphere. The March equinox also means that almost everywhere will have roughly equal times of daylight and darkness!

The March equinox marks several astronomical phenomena, too. The Sun rises directly in the east and sets due west during the equinox. The Sun will also appear exactly halfway between its northernmost and southernmost location in the sky.

The exact time of the March equinox occurs when the sun is directly above the Earth’s equator. This year, this occurs on 20th March at 11:04am for West Australians.
