Over here in Europe, the North American use of the word Holiday for Christmas is a bit confusing. Christmas remains in vogue to describe the events celebrated around the nativity celebration, though Santa Claus seems to have taken center stage in recent years.
For most people in Europe, the word holiday signifies what an American would call a vacation. Actually, as an atheist it really does not matter to me what terms is used, I remain grateful for any gifts I might receive.
