Prepare yourself – and your social calendar – for a month brimming with delightful social media holidays, from celebrating donuts and oceans to embracing furry companions in the workplace.
Here are some ways that brands are making the most of social media holiday celebrations throughout June to help inspire you to engage with your online communities.
Key takeaway
June has it all – from lighthearted celebrations like donuts and taking your dog to work to meaningful causes such as ocean conservation and blood donation. This month gives you a rich opportunity to show range: show your brand’s fun side, champion causes you care about, and build community as summer kicks off.
June 1. International Children’s Day #WorldChildrensDay
Take the chance to show appreciation for children and their families across social media on International Children’s Day. But don’t get confused about the date.

Content idea: Ask your audience to share a childhood memory that shaped who they are today. You can pair it with a nostalgic throwback from your brand’s early days.
