But where does the origin of the name “Halloween” come from? Well the term Halloween, originally spelled Hallowe’en, is shortened from All Hallows’ Even – e’en is a shortening of evening. It is now known as “Eve of” All Saints Day, which is November 1st. As Christianity started to spread, the church tried to supplant these pagan festivities with the Christian holiday (All Saints’ Day) by moving it from May 13 to November 1. Although All Saints’ Day is now considered to occur one day after Halloween, the two holidays were once celebrated on the same day.
