Spanish History Day Of The Dead

"I can celebrate the Day of the Dead?
In Spanish class, we have to celebrate the Day of the Dead … my philosophy professor / Professor History told me pagan in origin! We have to make food to go or do an alternate assignment … What to do? I do not think I want to do this … We to be a sin to celebrate this holiday? I only believe in Allah!
You can celebrate any day as long as they worship God "Y" not held in the name of God. For example, you can celebrate Labor Day. "But God told you to hold it. In the same way God does not forbid it either. So you may celebrate it as a mundane habit or ritual or ceremony, but do not put a relegious element in it. Religious elements limited the Koran.
