How’s this for an excuse to advertise a product? (Weird holiday guide – Updated for 2022)

I can hardly believe Christmas is in just a few days with the New Year right on its tail. It’s been another challenging year for a lot of people, with the ongoing pandemic situation. But I’m choosing to be optimistic that things will be better in 2022. 

That said, it’s pretty typical for business to slow down after the holidays pass. You may still see sales from people looking to use gift cards or spend cash they received as gifts. Plus, you may have returns and exchanges to process. Generally speaking, though, you won’t see as much business happening post-New Year’s as you do pre-Christmas. 

But looking ahead to the new year, I’ve updated my big list of weird and wacky holidays, which I’ve shared with you a few years in a row.

You can use this list to give your sales a boost during the post-holiday sales slow-down as well as any other time of the year. You can run promotions for unusual or lesser-known holidays or you can use the list as a source of inspiration for new design ideas.

For example, January 21, 2022 is Squirrel Appreciation Day. You could run a special promotion for this holiday and come up with squirrel-related design ideas.

Here are a couple results from a Google Image search I just ran for “squirrel mug”:

You really never know what might appeal to customers, and that’s what makes this list of weird and wacky holidays so helpful. Every single day of the year has at least one weird holiday — most have 3-4. So you’ll never run out of promotional or design ideas. 

Let’s check it out…
