What is the world celebrating today? People on social media observe numerous holidays and awareness days every day. We have carefully compiled all holidays in our social media holiday calendar.

In addition to these fun social media holidays a.k.a. hashtag holidays, there are also other types of days that fall under this broad category, such as awareness days, weeks and months and religious holidays.

All of the aforementioned are days that often start trending and that anyone on social media, especially small businesses with limited budgets, should be aware of. Why? Because they offer you a golden opportunity to get an interesting and timely message out right on time. When you know what will be celebrated on a certain day in advance, you can plan something special: a fun post, event or even a discount or a product launch.

I have compiled one of the most complete lists of social media holidays and awareness days, if not the most complete one, so that you wouldn’t miss a single one. Despite being very thorough and inclusive, I have left out ones that are so obscure that few people would have heard of it. This way you can instead focus on the holidays that matter.

Apart from social media holidays I have also included other important observances, including religious ones. The lists are regularly updated and detailed information about the most important ones added, so be sure to check back every once in a while.
