You’ve probably seen calendars filled with content ideas before, but not like this one!  Our December Content Calendar not only includes multiple ideas for each day of December, but it includes a whole bunch of DIY design templates to match. 

And to make it even more fun (and useful) we’ve included the following for the month of December:

  • Multiple celebrations for each day of the month in December
  • Bonus “Unique and Unusual” Holidays for extra ideas.
  • Week-long holiday celebrations
  • Month-long holiday celebrations

From International Chocolate Day to Talk like a Pirate Day and Bacon Day, there’s something in this calendar to spark your creativity. Not to mention all the major holidays from Christmas Day to New Years’ celebrations and all that’s in between!

How to Use the December Content Calendar Ideas

Here’s are a few tips and tricks that will help you get the most out of this calendar:

  • Choose the holidays and celebrations that suit your brand. Having some fun with unique and unsual holidays can be a great way to be relatable (and more human!) to your audience. Look at each holiday to see if it suits your “voice”.  
  • This list isn’t exhaustive. Use it as a starting point to think of ideas for content.
  • Dates may change. Please note that the holidays featured, dates of celebration and hashtags may change on any given year. We will do our best to keep it up to date, but please check for changes before publishing.
  • Check Instagram Hashtags.  Although we aim to share hashtags that are not banned by Instagram, we recommend you still check as the status of a hashtag can change overnight. Use the tips in this post to check hashtags first. Over 100k hashtags are banned by Instagram at any time (temporarily or indefinitely). This is because the hashtag or content posted under that hashtag violates Instagram’s Community Guidelines. Unfortunately it also includes “normal” hashtags like “Easter, Valentine’s Day, New Years”. They’re “banned” or removed when content posted under the hashtag violates Instagram’s guidelines. Banned hashtags may change – so always check first.
  • Get Creative. Use a template or add your own images and assets to illustrate the day you’re celebrating. Another alternative is to use a quote. For example, Walt Disney Day is a perfect opportunity to quote the famous man!

The Individuals with Disabilities Education Act (IDEA) was enacted on the 2nd of December, 1972. Before 1972, people with disabilities did not receive much if not any education.

“Never rub another man’s rhubarb” – The Riddler

Rhubarb Vodka – that’s one to add to the drink bucket list. A fairly new blend, rhubarb vodka was invented on a commercial scale in 2010, by Maple River Distillery. It could seem strange to make a vegetable-flavored spirit, but believe it or not – rhubarb is actually technically a fruit, and the whole plant itself is more of a herb. Any drink celebration is a good celebration, right? Don’t drink alcohol? Why not try a rhubarb lemonade or rhubarb syrup to mix a mocktail?

The third Friday in December brings us to Underdog Day. Life’s not all about the top dog, we love a good underdog story too! Apparently, one theory as to why we may be attracted to a good underdog story comes from the German psychoanalytical term “schadenfreude”, which is the experience of enjoying the tribulations of others. So if the underdog succeeds, it’s a great unpredictable celebration, and if they lose – well, they WERE the underdog, right? Interesting theory! Celebrating the underdogs of music, literature, movies, and life. Who’s your favorite unsung hero? Find out more here

Holly Day is celebrated every December 19th, recognizing the green plant with red berries that has been associated with Christmas for a long time.

Holly as a plant metaphorically represents growth and the life eternal. Today could be the day you make your own bough or wreath made of holly, and share your creation with your audience.

The third Thursday in December is Re-Gifting Day. Re-gifting can be seen as a negative action since it is assumed the person who gave you the gift in the first place may have put a lot of effort into thinking of your gift. It doesn’t have to be frowned upon, there is so much ‘stuff’ in the world, and the gift of giving, or re-giving in this case, can put a smile on someone’s face. Traditionally a fun day for office workers to re-gift unwanted office gifts, but it could also be used as a way to give back to those in need. Maybe put a twist on it and pay it forward in some way.

“Some things in life are bad
They can really make you mad
Other things just make you swear and curse
When you’re chewing on life’s gristle
Don’t grumble, give a whistle
And this’ll help things turn out for the best
Always look on the bright side of life”
Eric Idle
