Origins and Traditions of Halloween

Halloween has Celtic origins and was celebrated on October 31st, marking the end of summer and the beginning of winter. The Celts, who believed that spirits returned on this night, performed religious rituals and wore frightening costumes to ward them off. The colors of Halloween, orange and black, are also of Celtic origin, representing the harvest and the winter, respectively. Black cats are also a popular symbol, believed to possess special powers. In the 18th century, the Catholic Church renamed the evening of October 31st 'All Hallows' Eve', the day before All Saints' Day on November 1st.
