I like to remind pedants in Britainland that the word "holiday" was traditionally used on the right-hand side of the Atlantic right into the 20th century to mean any time off from work, not just full-on seasonal vacations.
Pedants will remind you that "holiday" is just a mis-spelling/pronunciation of "holy day" and that Christmas meets that definition. If you don't want to recognise it as such get back to work.
