You’ve heard it time and time again – posting on social media consistently is one of the best ways to grow your account. But it can be hard to fill up content ideas for nearly 365 days. That's why we’ve created this holiday guide of both official and non-official holidays you can post about throughout the year.

While it’s important to post content revolving around your business’s products and services, it can also be fun to change things up and post about other topics as well. We hope this list helps you flesh out your social media calendar for 2023.

Creating social media posts for official holidays is a great way to highlight important days and also celebrate the diversity of cultures and celebrations. When posting about other cultures and religions, make sure to do your research so you can highlight the holiday accurately and respectfully.
