Holiday Special

A mostly-American phenomenon: any one-off or other special television production created solely to air on or around a holiday, with the intent of celebrating or "explaining" the holiday. The accuracy of such works is subject to both Did Not Do the Research and They Just Didn't Care, and at worst a special about an ostensibly religious holiday can end up being the Theme Park Version.

And then, of course, there's the inevitable Peanuts special...

See American Holidays for a list of viable candidates for Holiday Specials.

The Super-Trope to the Christmas Special. Related to, but not to be confused with, Holiday Mode.

Contrast You Mean "Xmas", where a bland, generic holiday is invented to take the place of a real one.
