Halloween is actually an Irish holiday. Called Samhain (SOW-ann) in ancient Celtic tradition, it’s the traditional autumn festival when the spirits of the dead walk the earth. Translated to the Christian era from the pagan, it became All Hallow’s Eve, the night before All Saint’s Day. Thus the spirits and the jack-o'-lanterns carried from one tradition to the next. Turnips used to be carved out and lit to frighten away unwanted interaction between the living and dead on the long dark roads.
