Halloween 2025 falls on a Friday. Halloween is a holiday celebrated each year on October 31, the eve of the Christian feast of All Saints. It is widely celebrated in many parts of the world, particularly in the United States, Canada, the United Kingdom, Ireland, and Australia.
The tradition of Halloween originated with the ancient Celtic festival of Samhain, which was celebrated on November 1. The Celts believed that on the night of Samhain, the boundary between the worlds of the living and the dead became blurred. As a result, they celebrated with bonfires, costumes, and feasts to honor the dead and ward off evil spirits.
