Snuggle up and get ready for longer nights and shorter days leading into winter – the Autumnal Equinox of 2016 officially starts today, Sept. 22.
According to reports, the sun is passing directly over Earth’s equator marking the beginning of autumn in the northern hemisphere. This creates a day and night equal in length.
Meteorologists use the equinox, a biannual event, to identify the change in seasons. They say it happens on or around March 22 and on or around September 22 annually.
In the southern hemisphere, the seasons are flipped and today’s equinox marks the start of longer days and shorter nights.
