What are social media holidays?

Social media holidays are events that offer marketers the opportunity to create engaging content around memorable calendar dates.

They can be fun or charitable, local or global, but they must resonate with your or your client’s target audience.

To give you an idea, here's how Chips Ahoy does it. They don't just celebrate the National Cookie Day but also a plethora of other micro-holidays, such as National Eat Ice Cream For Breakfast Day, or even Mercury Retrograde (which is not even a holiday, but it's a good excuse to get closer to your audience).

These micro-holidays often present an opportunity for marketers to get creative, whilst planning ahead and filling up their social media content calendars - so celebrating them is a win-win!

Why should social media marketers celebrate holidays?

Being able to keep on top of news and trends is what makes a great social media marketer. That’s why it’s so important to have a well thought out content process to save time and keep you afloat.

In such a fast-paced industry, people expect to see content that mirrors what’s happening in the real world - so much so, that even NASA has to follow the trends and keep up with hashtag holidays:

Today is #NationalPuzzleDay ! One of the major puzzles in astrophysics is the expansion rate of the universe, also known as the Hubble constant. Completely understanding the universe’s expansion might require new laws of physics:

But as a marketer, it’s not just followers that you have to make an impression on. You are likely to have goals and KPIs to reach, and will need to be able to show ROI for your efforts.

So, how will filling your calendar with social media holidays help you achieve those results?

Celebrating social media holidays can help you increase brand awareness and reach

Simply adding relevant hashtags to your holiday-themed posts allows them to be seen by a much wider audience, as well as create a buzz around a brand.

Sharing hashtag holiday-themed content helps to engage your audience

If a brand isn’t the easiest to market, then posts about social media holidays can offer an alternative angle to promote the product or service in a more engaging way.

Online electrical retail brand AO does a great job of this on their social media channels. While they might not sound like the most exciting company, they use social media holidays to make their appeal more universal and encourage engagement from their audience, and it pays off!

Creating themed content around social media holidays allows your brand to show a sense of authenticity

Sharing content that is linked to charitable causes and events is just one of the ways how you can demonstrate that a brand is human and authentic - which is something that consumers find really important on social media.

5 actionable steps for creating high-quality content and celebrating social media holidays

Now that we’ve established why celebrating social media holidays should be an integral part of any content marketing strategy, you might be in need of some quick pointers on how you can easily incorporate these types of posts into your or your client’s social feeds.

Here are our five actionable tips for celebrating and creating content based on social media holidays.

1. Use a social media holidays calendar to help organise your campaigns and dates in one place

From national holidays like New Year's Eve and Labor Day to fun, food-related events like World Chocolate Day and National Donut Day, there are so many social media holidays for marketers to take advantage of. So much so that it can be a struggle to try to keep track of them all! That’s why it’s useful to have a social media calendar which contains all of the relevant dates that you intend to celebrate.

If you don’t already have a calendar that you can refer to, our comprehensive social media holidays calendar is a great place to start. It comes in the form of a handy website page that's easy to use and share!

2. Be visual with the content you create

When creating posts for social media, the more visual and eye-catching you can be, the better. In fact, Facebook posts that include images can garner up to 2.3 times more engagement than those without! 

In real terms, this means creating hashtag holiday-themed posts using varying content types, most likely a mixture of video, photo and graphics.

You can use Sendible's smart compose box to create a post for any platform whenever inspiration strikes using anything from a photo to video to simple text.

We love this example from Refinery29 , who have created a fun and colourful graphic for Instagram in aid of #MakeAFriendDay. It instructs their Millennial following on how they can make friends as adults. It’s a simple but effective post, which has garnered over 250 comments!

3. Remember that original content is the best kind of content

It’s no secret that social media can be a noisy place. Marketers can struggle to get their messages heard above the masses, which is why originality is the key to great social media holiday content.

...That means it’s time to get creative - especially if you have a designer or photographer at your disposal!

You could try creating some Instagram collaborative posts, making gifs or posting photos starring members of your team. Hopping onto holidays like International Coffee Day, National Taco Day, and International Cat Day are all ways that your brand can show authenticity. We love how ZSL London Zoo celebrated Valentine’s Day by showing off their animals and accompanying the posts with some very punny captions!

In addition to generating extra engagement, social media holidays can be used to celebrate team members your place of work and really show who you are as a brand.

Remember that it’s all about authenticity - content which features real faces is 32% more likely to receive comments on Instagram.

4. Involve the audience as much as you can

Whether it’s tweeting out questions for them to answer or asking them to post a photo to Instagram via a holiday hashtag competition, meaningful engagements with followers and fans are exactly what a brand should aim to generate on social.

Social media marketing is all about making connections with other people. How do you do that? You interact with them, of course! Celebrating social media holidays is a great way to open up a dialogue between your brand and its followers.

Being specific and direct about what you want from your audience is important here - see how Sanrio instructs viewers of their post on exactly how they want them to respond:

Learning how to write great captions for Instagram posts is half of the battle, but if it makes it easier to ask the right questions, then it’s worth it!

5. Use influence to attract attention to worthy causes

Every organisation has a voice, and it’s important that they learn how to use it. After all, businesses should have social consciences, too.

There are now so many noteworthy social media holidays which draw attention to marginalised groups, and charity causes that it would be foolish not to show your true colours and get involved!

The most important thing to remember is to keep your celebrations relevant to your specific audience. Otherwise, your posts could appear as random, and you may alienate an audience instead of pulling them closer. Going back to the benefits we mentioned before, you can get creative and celebrate events that are not directly related to your brand, as the Natural History Museum did on LGBTQ+ History Month celebrated in February in the UK:
