I'm always sharing about unusual days of celebration (and popular ones) and I can honestly say that I have never looked forward to a year to do it in… more than 2021 (I am sure you're the same, given the year we've had in 2020!).

From Pizza Day to the Academy Awards to Mother's Day to Cinco De Mayo… there's plenty of social media holidays to help you kick off your social media content as we head into 2021.

What comes with the Social Media Content Calendar?

I've included the following in this post with the 2021 Social Media Content Calendar:

  • a quick reference guide to social media holidays for each month including some weekly and monthly themes.
  • an overview of ideas for how to use the social media holidays – what you can create and how to share them.
  • a list of tools to help you create visual content for 2021 social media holidays – using our Social Media Content Calendar.

Why use Social Media Holidays?

Creating and curating content can be hard. It's relentless and sometimes you need a little lighthearted content to boost engagement. Let's face it, we all love quotes, images and videos around special days throughout the year. It's content that wins, again and again.

So make sure you include some social media holidays in your content and use our content calendar “infographic” to help remind you, then click through any time to see the full list on this 2021 Social Media Content Calendar.

Hot Tip: use the infographic for quick inspiration (we've included the 2021 holidays we like the most on the infographic but you can then dive deeper below with a longer list of social media holidays listed in this post below:

How to use the 2021 Social Media Holidays Content Calendar:

Here are a few ways you can use the ideas on the infographic or in the list below:

  1. Create images based around the holiday – it could be a quote, meme, saying, tip or image with text overlay. Use two of my favourite DIY Design tools, Canva or Easil, to help you.
  2. Create a short video around the social media holiday. Is it Pizza Day? Maybe make a short video with some pizza fun facts. Use my favourite video tool, Wave to help you. 
  3. Create a fun GIF to celebrate the holiday you are sharing. Use my favourite GIF creation tools, Easil or Giphy to create a GIF.
  4. Create an email-based around a social media holiday theme – ie St Patrick's Day or Mother's Day. Send your subscribers a special deal for those holidays.
  5. Create an offer on social media that you can share with your audience.

You are only really limited to your imagination when you use the 2021 Social Media Content Calendar!
