September 2021 Content Ideas and Inspiration

Let’s welcome Autumn this September and enjoy the changing colours in nature, seasonal fruit and vegetables and getting cosy in jumpers and a comfortable pair of wellingtons!

One of my favourite quotes about September’s weather is:

“By all these lovely tokens September days are here, with summer’s
best of weather and autumn’s best of cheer“ - Helen Hunt Jackson

Other than lovely changing weather, September is the month to start fresh. This could mean either getting back to work after relaxing Summer holidays or going back to schools and universities for children and students.

The name of the ninth month of the year – September – comes from the old Roman word “septem“, meaning “seven”, because in the Roman calendar it was the seventh month.

The Romans believed that the month of September was looked after by the god of the fire and forge – Vulcan. Therefore, they expected fires, earthquakes and volcanic eruptions in this month.

In many parts of the world, September is the first month of autumn and it is associated with the beginning of school.

September is the only month with the same number of letters in its name in English as the number of the month.

The Anglo-Saxons called September ‘Gerst monath’, meaning ‘barley month’ and is associated with harvests and plentiful crops.

In any year, no other month ends on the same day as September.
