What is Boxing Day and why don't most Americans celebrate? Everything you need to know

The most miserable day of the year has to be the day after Christmas.

You spend the previous 48 hours having a blast with your family. You’re wrapping and exchanging gifts, eating food, watching sports and just generally having a grand old time.

Then, all of a sudden, the day is over and, for many folks, it’s back to reality. The Christmas music stops. The movie marathons are suddenly over. You’re somehow back at work.

That’s how it usually works in the United States, anyway.
