Oh, um... [Odd. She's never talked to anyone who didn't know what a holiday was...] No. It's a day, or sometimes several days, where people celebrate certain events happening. Christmas, the one coming up at the end of this month, is a holiday where people give gifts to each other and celebrate joy and coming together as family or friends.

It's also religious, for many people, but I'd rather focus on the other things.
