The first day of autumn has arrived – a glorious time of year filled with woolly jumpers, knitted scarves and the occasional game of conkers. The temperature has dropped, days are getting shorter and the leaves are changing colour – it can only mean thing: autumn has arrived…
When is the first day of autumn?
There are two options to chose from – and it depends whether you follow the meteorological or astronomical calendar. There’s three weeks difference between them both.
In meteorological terms autumn begins today, on September 1, and ends on November 30. The meteorological calendar uses our Gregorian calendar to split up the four seasons into three month blocks, which, according to the Met Office, makes it easier to observe forecasting and compare seasonal statistics.
Astronomers base the date of the seasons upon celestial events, in autumn’s case the autumnal equinox, when night and day are roughly equal length. In 2017 this takes place today, on September 22.
