The ultimate social media vacation calendar for 2021 [Template]

Whether it’s International Cat Day, Pizza Day, or Pirate Talk Day, the internet celebrates a holiday almost every day.

You probably don’t celebrate all of these social media holidays. Think about it. When was the last time you saw a dark holiday or observation day and thought, “Yes, I’m celebrating”?

Some of these holidays might just be too silly for your brand to get involved in. Despite all the curiosities, social media managers always observe trends and holidays that they can use for brand awareness.

We certainly don’t recommend sharing content on social media and then putting a completely irrelevant hashtag on it, but you should still take some time to recognize the branding opportunities that could come your way over the next year.

If you ignore all of the vacation opportunities you may be taking, you may be missing out on valuable opportunities to catch trending topics with fun and relevant “vacation” content on social media.

From food to politics to animals and everything in between, there are a multitude of observation days around the world where marketers can exchange content relevant to their industry, participate in a movement or simply create more awareness.

To help you plan trending vacations, we’ve created a bookmark list and a downloadable calendar so you can get automatic reminders.

Downloadable holiday calendar

Below is a Google Calendar for Social Media Holidays that you can use to keep track of all the holidays.

Aside from the 2021 holidays, we’ve also set dates in the calendar that should be repeated annually – either on the exact date they occur or the day of the week they occur within the month.

Do you want to wrap up your 2021 calendar with some upcoming holiday posts? Tap the “+” icon in the lower right corner of the calendar below to add it to your own Google Calendar.

As a reminder, click the plus sign below to add it to your own Google Calendar list.

National and global holiday calendar: 2021

The list is not exhaustive (there are many food-specific holidays), and these dates and hashtags are subject to change. However, this is a great starting point for social media marketers who want to learn more about the trends and planning their content in a fun and engaging way on Twitter and other social platforms.
