i don't mind if people wish me happy whatever.
But! if you're trying to get on someone's good side, wish them the holiday you know they celebrate but you don't. For example, one of our profs wished us happy chinese new year in chinese (apparently he was taking classes) once and it made all the chinese in the class happy, me included. I would think someone is very considerate if they were to do that. But I even celebrate the muslim new year when invited, and also diwali. So I really don't care much for the religious aspect of holidays.
