Halloween has its origins in pagan festivals held around the end of October in England, Wales, Scotland and Ireland. People believed that, at this time of year, the spirits of dead people could come 'alive' and walk among the living. They thought that it was important to dress up in costumes when venturing outside, to avoid being harmed by the spirits. This may be the origin of the Halloween costumes seen today. In Puritan times, Halloween celebrations were outlawed, but they were revived in later times.
Halloween used to be called All Hallows Eve, or the day before All Saints' Day, observed on November 1. Halloween is also known as Nut-crack Night, Thump-the-door Night or Apple and Candle Night. Some people call Halloween Bob Apple Night or Duck Apple Night. This comes from a traditional game played at this time of year and known as 'apple bobbing' or 'apple ducking'. A bucket or other container is filled with water and one or more apples are floated on the water. The contestants take turns trying to catch an apple with their teeth. They must hold their hands behind their backs at all times.
