We’re often missing some fun and laughter within the seriousness of business or impactful charity work, and some of the dates found in this month could help with this. Read through the list of dates and pick out the ones that immediately make sense to your work. They’ll be easy to tie into your content planning. When it comes to well-known days across the year, an acknowledgement post might be obvious, but thinking outside the box could spark an entire blog or awareness piece.
💡 Tip for specialty industries: If you work in a trade or profession with an Australian governing body, it’s always worth searching for your industry’s specific awareness calendar as well. Those specialist dates aren’t included here, but they can be a goldmine for relevant, high-impact content.
Generating bigger, more substantial content brings more benefits than just showcasing thought leadership – it can greatly assist your website SEO, which Google loves! And when it comes to the fun stuff, take the lead and let those quirky dates spark creativity in your team too.
Remember, you don’t always need to include a sales push in every post. But if you can tie some of this month’s dates to your services or products, give it a crack. And if it all feels a bit whimsical, join a Social Ocean content creation workshop to build your confidence and upskill at the same time.
