You can run business promotion for any holiday. This morning on my way to work, I heard an ad from a body wrap service on radio trying to get their customers in their store before Halloween. What does body wrap have anything to do with Halloween? Because all the great costumes for Halloween usually come in X SM :-)

Is it an legitimate reason? Of course it is. It helps people to find a use for their service. If you look up holiday on the web, you can find all types of holiday throughout the year, even some holidays that you might have never heard of.
