Whether it’s International Cat Day, Pizza Day, or Talk Like a Pirate Day, it seems like almost every day, the internet is celebrating a holiday.
Whenever I log onto Twitter, I quickly scan what’s trending on the left-hand side of the screen. Have you ever had this experience — when you see an obscure holiday or observance day trending, and you think to yourself “Yup, I’m celebrating that”?
Some of these holidays might be simply too silly for your brand to engage with (and we certainly don’t suggest sharing content on social media and then tacking on a completely irrelevant hashtag for the sake of traffic — that’s just plain annoying). But others might not be. You could be missing valuable opportunities to take advantage of trending topics with fun and relevant “holiday” content on social media.
From food to politics to animals and everything in between, there is a plethora of observance days worldwide during which marketers can share content relevant to their industries, get involved in a movement, or simply generate more awareness.
To help you plan for trending holidays, we created a list that you can bookmark, as well as a downloadable calendar so you can get automatic reminders. The list isn’t exhaustive (there are a lot of food-specific holidays out there) and these dates and hashtags may still be subject to change. But this is a great starting point for social media marketers who want to learn more about what’s trending and how they can plan their content in a way that will be fun and engaging on Twitter and other social platforms.
Tap the + symbol in the lower right-hand corner of the calendar below to add it to your own Gmail calendar.
