Even though the holiday season is well over, that doesn’t mean we’re done. It seems that year after year, there’s so much more to celebrate. Thanks to the ever-growing popularity of social media, holidays seem to appear out of thin air. It’s hard to log on and not see a special day trending.

We’re not the first ones to admit that some of these holidays are ridiculous. But, just because they’re a little ‘out there’, doesn’t mean you shouldn’t be hopping on the trends for likes, shares, and comments.

Before you start posting for any old holiday, we want you to take a step away from the hashtag. Long gone are the days of just posting to post. You should be taking the time to craft posts that speak to your target audience. And that means that there are holidays that simply aren’t worth your efforts.

Start with creating a social media calendar. Determine what days and times are the best for your posts and build from there. Make sure to schedule posts for the major holidays that make the most sense for your business. For example, most people celebrate the New Year in some capacity while something like St. Patrick’s Day might not speak to your audience.

Once you’ve got your major holidays identified, it’s time to consider the fun ones. These hashtag holidays cover a broad range of niche topics that interest social media users. So, if your audience is participating in the fun, you should be too. Take some time to identify which of the hashtag holidays make the most sense for your business and then craft compelling posts for those dates.

There are a lot of holidays to consider, so we decided to list them for you by the month. Take a look at this complete list of hashtag holidays for 2019 and start brainstorming how you can incorporate them into your social media calendars!
