Some stores are closed for holidays and it is best to ask what their hours will be. "When are you closed?" is a general question and can be used, but the staff might not know what you are talking about. For more detail, try "What are your holiday hours?".This is more direct and they will know that you mean the next upcoming holiday. Perhaps they aren't closed on the holiday but they have shorter hours open and closing, this will let you know what those are as well.
