All Hallows' Eve falls on 31st October each year, and is the day before All Hallows' Day, also known as All Saints' Day in the Christian calendar. The Church traditionally held a vigil on All Hallows' Eve when worshippers would prepare themselves with prayers and fasting prior to the feast day itself.
Halloween has its roots in the ancient, pre-Christian Celtic festival of Samhain, which was celebrated on the night of October 31. The Celts, who lived 2,000 years ago in the area that is now Ireland, the United Kingdom and northern France, believed that the dead returned to earth on Samhain.
What is Halloween trick or treat?
Children in costumes travel from house to house asking for treats such as candy (or, in some cultures, money) with the phrase "Trick or treat". The "trick" is a (usually idle) threat to perform mischief on the homeowners or their property if no treat is given to them.
How do we celebrate?
As millions participate in the fun of Halloween on the night of October 31st, few will be aware of its ancient Celtic roots in the Samhain (Samain) festival. In Celtic Ireland about 2,000 years ago, Samhain was the division of the year between the lighter half (summer) and the darker half (winter). At Samhain the division between this world and the otherworld was at its thinnest, allowing spirits to pass through.
Christianity incorporated the honouring of the dead into the Christian calendar with All Saints (All Hallows) on November 1st, followed by All Souls on November 2nd. The wearing of costumes and masks to ward off harmful spirits survived as Halloween customs. The Irish emigrated to America in great numbers during the 19th century especially around the time of famine in Ireland during the 1840's. The Irish carried their Halloween traditions to America, where today it is one of the major holidays of the year. Through time other traditions have blended into Halloween, for example the American harvest time tradition of carving pumpkins.
