How’s this for an excuse to advertise a product? (Weird holiday guide – Updated for 2020)

Phew! Another holiday season is in the books. I can hardly believe we’re already a week into 2020. I don’t know about you, but last year went by insanely fast for me. 

Business is likely to slow down over the coming weeks, although sales may still come from people looking to use gift cards or spend cash they received as a gift. Plus, there’ll likely be returns and exchanges to process as well. 

But looking ahead into the new year, I’ve updated my big list of “weird” holidays, which I’ve shared with you the last couple of years. You can use this list to rev up your sales throughout the year by running promotions for unusual or lesser-known holidays. Or, you can use it to come up with new design ideas based on this list of holidays.

For example, January 20, 2020 is National Cheese Lovers’ Day. You could run a special promotion for this event and come up with cheese-related design ideas. It sounds silly, I know. But take a look at what a quick Google Image search comes up with:

Come up with new ecommerce design ideas and ways to promote your products using this list of weird holidays

As you can see, there’s a lot of design inspiration that would be perfect for this oddball holiday. And the list I came up with includes at least one wacky holiday for every day of the year, so there are tons of opportunities for new designs and promotions.

  1. This is a great list! I have started a holiday site (although I haven’t put much into it yet) and thought about adding “weird” holidays! This list is great and will give me something to work off of, when I have time to devote to it. Thanks so much!
