December has no shortage of social media hashtag holidays that you can use in your content marketing efforts, which can help you fill in your content calendar.

Social media holidays (or hashtag holidays) can also break up the “me-centric” content that so many companies and individuals post often on social media.

They can also help you showcase your “softer” side as well as your people.

Here are a few ideas to spark your creativity along with the hashtags you can use to boost the visibility of the posts.

While this list isn’t exhaustive, and these dates and hashtags may still be subject to change, this is a great starting point for marketers who want to incorporate social media days that are trending and plan social content in a fun and engaging way.

Of course, not all of them will make sense for you or your organization. (I’m personally a fan of National Bacon Day). Choose the ones that fit with your brand and business.
