September Social Media Ideas

Hello September in Paint

Here we are in September already and that means a full 30 days of social media content to create.  Here at Omnia, we’re all about doing the hard work for you, so we have created a full 116 September social media content ideas for you!

Complete with hashtags, Gifs to download, and some graphics, too, all you need do is simply select a few days that work for your business; they can be serious, aimed at raising awareness around a particular issue, or humorous to create some engagement amongst your audience.  Feel free to be creative and to put your own spin on a day – there are no rules, so be brave and do what works for you.

If you need any help in using these September social media ideas, then head over to our recent blog post on using awareness days.

If you’re looking to create quality content, but don’t want to spend a whole heap of time doing it, then read on!

So, within this blog, for every day of the month, you’ll find at least one (often several!) social media ideas. We’ve included holidays, awareness days, both national and international, for you to use.  Why not use some of the days as the starting point for conversations with your followers?  Ask their opinions, ask questions, create polls…the possibilities are endless.

September Social Media Ideas Day by Day

1st Letter Writing Day. Head on down to your local stationery shop and stock up on materials because today is all about physical letter writing – not emailing, not messaging, yes, letter writing. When was the last time you sent a proper letter to someone…or received one for that matter?

Also, Global Talent Acquisition Day, Ginger Cat Appreciation Day, Tofu Day


Envelope and Letter saying Happy Letter Writing Day

2nd Calendar Adjustment Day. Did you know that, once upon a time, January the 1st did not mark the start of the year? It was only after 1751, when Britain adopted the Gregorian Calendar that January 1st became New Year…and not 26th March, when it had previously been celebrated. Confused, much?

Also, VJ Day

Don’t forget to include photos in today’s social media posts to show your community awareness.
