Holiday Traditions

So I know the holiday season is over but I was having this convo with a coworker and I was really intrigued by the different traditions that different people and cultures have. My family for example, we don't wash our hair, clothes, mop, or sweep on New Year's eve and New Year's Day, because we believe that's it washes someone out of our family. My coworker does the opposite because she believes that it cleans all the bad energy from the previous year out of your house. What are some of your holiday traditions? (I didn't know if this was the right place to post this or not)
