December 2021's Full List of Holidays and Observances

·5 min read

For many people, December is all about preparing for Santa's arrival, but that's not the only celebration that takes place throughout the month. In addition to Christmas and all the festivities that come with it — like National Christmas Lights Day, National Christmas Movie Marathon Day, and Christmas Card Day — December holidays and observances include the last days of Hanukkah, the beginning of Kwanzaa, as well as Boxing Day, New Year's Eve, and dozens of other celebrations, ranging from Let's Hug Day to Bathtub Party Day. If you're looking to start planning out your month (and to discover holidays you probably didn't even know about), then consider this your official December 2021 holiday guide.

Between holiday decorating and gift shopping, you probably find that the month of December flies by every year, and before you know it, it's time to make your New Year's resolutions for 2022. And while you may be using your advent calendar to count down to December 25, there's a reason to celebrate every day in December, both before and after Christmas Day. From solemn remembrances, like the National Day of Remembrance and Action on Violence Against Women, to silly traditions, like Pretend to Be a Time Traveler Day, here are all the holidays and events that are observed in December 2021.
