"Halloween" and "Dead's day"

These are the differences between Halloween and Dead's Day:
The Halloween is an American tradition where one likes sweets and will not be granted if there is a mischief. Also people use costumes beings fantastic. In Mexico, children come to "calaverear" to ask too sweet, but first they have to pray at the altar or ofrenda that are deployed and are not required to be disguised. I think that the Dead's Day is more traditional and more real.
