Looking for some inspirational content to post about in December? You are in the right place. Observing trending social media holidays is extremely popular and the trend is growing. Knowing what to celebrate much in advance gives you the upper hand, since you have time to plan your content and perfect it. When the social media holiday is trending on Twitter or Instagram it is already too late to jump on the bandwagon. In other words, make sure you always keep track of what’s going on.

This list of ours contains all major social media holidays and normal holidays celebrated in December 2024. Minor ones have been left off the list, so you can be sure that you won’t end up observing a holiday that no one has even heard of.

➡️ In addition to featuring monthly national days, I have a National Days Calendar 2025 that highlights one popular national day for each day. The calendar is also available as a printable version in my Etsy shop.
