Have you ever got up in the morning, checked Twitter and realized that you missed out on an important day? If you didn’t realize it was Pi Day or Hug Your Dog Day or Everyone Wear Red day, it’s hard to be prepared, isn’t it? You either scramble to come up with something good or you post something you found somewhere.

Taking part in fun and memorial days, months, etc put you in the middle of the conversation and let your audience know you’re connected and care.

I started working on this list when I was consistently caught of guard by commemorative days that I SHOULD have taken part in. Whether it was a day set aside to show respect for a cause, a day created to raise awareness or a day that was meant to be fun and light-hearted, it’s nice to be a part of them with your audience.

If you like making a calendar for your content, add this to your posting calendar and set it to repeat so you’re one and done.

I have included the list for each month below. Be sure to bookmark this page and check back often for new days, fun ideas and more.
