Autumn is the time of year that the poet Keats called the ‘Season of mists and mellow fruitfulness’, and how right he was. Autumn is the season famous for its harvest time, turning leaves, cooling temperatures and darkening nights.
We often talk about it beginning to feel like Autumn when the nights start to draw in and temperatures start feeling cooler. Here are a few facts about this mellow season…
So when is the first day of Autumn? It depends on whether you are referring to the astronomical or meteorological autumn. There are two different dates when Autumn could be said to begin. Autumn, as defined by the Earth’s orbit around the sun, begins on the Autumn equinox which falls on 22 or 23 September. However, for the purposes of recording climate data, it is important to have set dates that can be compared, so the meteorological Autumn always begins on 1 September.
People born in Autumn live longer!
A study in the ‘Journal of Aging Research’ found that babies born during the Autumn months are more likely to live to 100 than those born during the rest of the year. Their study found that 30% of US centenarians born during 1880-1895 were born in the Autumn months. I had never heard that before… and as my birthday is right on the cusp of Summer and Autumn, who knows what that means for me!
What is an equinox?
The word ‘equinox’ comes from the Latin equi (meaning equal) and nox (meaning night) accounting for the equinox marking the time when day and night are of equal length. We often notice the nights begin to draw in from this point as after the Autumn equinox, the night becomes longer than the day, until this is reversed at the Spring equinox.
A date for your diary – 24 September 2303
Generally speaking, the Autumn equinox always falls on either 22 or 23 September, but not quite always. Because the Gregorian calendar is not quite in perfect symmetry with the Earth’s orbit, the Autumn equinox will very occasionally fall on September 24. This last happened in 1931… and will next happen in 2303.
Autumn, or Fall?
I always think of ‘Fall’ as the North American version of the word ‘Autumn’ and as being the ‘new kid’ on the block! However, the term fall was actually in widespread use in England until relatively recently. Originally a shortening of the phrase ‘fall of the leaf’, the phrase was common in England in the 17th century. Although Chaucer first used the word Autumn in 1374 it did not become common usage until the 18th century.
Personally, I think Autumn is a lovely word and I shall continue to use it to refer to this beautiful time of year. Right, I’m off to sweep up some leaves in the garden now…
