At this time of year, I often see a question which never fails to perplex me. Many people feel the need to ask, "when is Halloween?" That's like asking when is Christmas or when is the Fourth of July. There’s a set date for Halloween. It’s not a holiday with a variable date like Easter. Halloween is always Oct. 31, just like Christmas is always Dec. 25 and July 4 is, you guessed it, July 4.
