Almost every day of the year is some sort of a holiday on the internet and you definitely don’t want to miss the chance to celebrate them with your followers. Whether it’s Marzipan Day, Cat Day, or Halloween you want your social media accounts to be prepared to properly celebrate. That’s why our team created The Definitive 2021 Holiday Calendar so you don’t have to.

With this holiday calendar, you can review the holidays, pick the ones that are relevant to your company profile and to your following, then create social media content for those special days. You can have a social media campaign that either aims to drive traffic, attract more followers or raise brand awareness. Just make sure to clearly define your goal and the specific boost in your KPIs that you want to achieve with your campaign.

And don’t forget about the hashtags, each holiday or observance day comes with its own hashtag, so don’t forget to use that for good social media exposure. Just keep in mind to use the less popular variation of the holiday hashtags too, don’t just go with the crazy popular #MerryChristmas-type hashtags.

For an amazing social media success, try to go beyond making posts on those special days. Discounts, fun visual content, or maybe even creating special limited edition product lines can lead to great success. The opportunities are limitless.

To help you plan a successful social media calendar for this year, we created this calendar which is full of holidays and observances. Both international and US holidays/observances are included.

Below you can download the Google Calendar .ics file and add it to your own calendar of choice. Review the calendar and pick the events that are most relevant to your company and followers. Each event has a description with brief info about the event.

Even if you do not plan your social media calendar for the whole year, this calendar still can help you be reminded about the upcoming holidays and observances. Just make sure to adjust the notification settings according to your preferences.

Using Hashtags for Holidays

Using hashtags is essential for holiday posts. These give you the opportunity to gain extra exposure and present your brand to new prospects. Consider them as free ads if you will. Not every holiday has a popular hashtag, but even if it’s unpopular you might want to explore the uncharted waters to see whether it works for you or not. Being seen in unpopular feeds is much easier than in a feed that has a new post popping out every second.

And as always, don’t go overboard with hashtags, use them wisely. Unless its Instagram. Everyone goes overboard with hashtags on Instagram. In case you don’t know this trick, you can post your hashtags in the comments section so your post doesn’t look messy. You can even delete the comment once in a couple of hours and then repost it so you can be added to the top of the hashtag feed again.

Holiday Campaign Tips

If you decided to have a holiday campaign, like a sale or a deal, we suggest you announce it beforehand. Of course, it all depends on the type of your campaign and your business goals, but it is usually much more beneficial to let people know beforehand. Even if they’re not interested in your offer they’ll still be reminded about your brand.

Let’s say you have a Christmas sale. During Christmas, there are so many posts it’s very hard to be noticed. People will just give your post a glance and scroll ahead. This way your campaign might not get the attention you want. However, if you start your campaign beforehand, the chances of your campaign being noticed are much higher.

Greeting Cards: When to share?

Greeting cards are always a good idea! Especially if your designers can take a fun spin on the design, people will be more drawn to engage with the post. It’s a good idea to share these a day or two before the major holidays so that more people will notice it. Otherwise, if you share it on the day of a major holiday it might be lost in the social media chaos.

Social Observances

For observances like Clean Your Desk Day and Earth Day, you can jump on board and show how your company chose to celebrate the day. For Clean Your Desk Day, you can think of a fun way to show how your staff chose to clean their desks. For Earth Day, you can participate in an environmental cause and take the chance to state how your company is contributing to help keep our environment clean and healthy.

With some holidays, you can not only remind people about your brand but also show how strong your culture is, which some people take into account when interacting with a business.

Giveaways, Contests, and Other Engaging Activities

Giveaways and contests are an amazing way to get your followers to engage with your brand on social platforms. And holidays are a great excuse to have one! Take traditional social media competitions, i.e. photo caption contests, “like to enter”, “random comment wins”, and add a little holiday theme to it. Now you’ve got yourself some green arrow ups in your SM analytics.

The Aftermath

Don’t forget to create separate reports for your campaign performance of each holiday. This way, next year you’ll have some solid info on what works for your brand and what doesn’t. Data can be a great tool to get you forward in your social media efforts so always summarize your performance for each holiday campaign. Just make sure to use reliable analytics tools for this task.

Whether it’s the 4th of July or Hot Sauce Day, be fun, be creative and let your customers know that you are there to help them make every day a celebration.
