Happy Halloween!

In the Northern Hemisphere, October is very much Fall and pumpkins and Halloween. However, there is still a lot for those in areas that don’t celebrate Halloween or for whom it is Spring. October 13 should be of particular interest to content marketers because we should all be using Plain English.

A word of caution if you’re in the United States. While it’s still a Federal holiday, fewer states are celebrating Columbus Day. It celebrates a particular version of America’s colonization that doesn’t represent all that occurred. Read our blog post for more information on the day, and ways it is changing.

Last Update: January 17, 2021 – 248 Hashtag Holidays

This list starts with the hashtag holidays by day, followed by the celebration months. There’s a little duplication because that’s the nature of made up holidays. Some also rotate year-to-year and we’re still working at identifying those. If you know a holiday that’s missing or we’ve made a mistake, please let us know!

Hashtag holidays with rotating dates are identified by the year. Official public holidays have the country and state, if state-based.
