Halloween, also known as All Hallows' Eve, is an annual festival that takes place around the world on October 31, the eve of the Christian feast of All Hallows. It is thought to have originated with the ancient Celtic festival of Samhain, when people would light bonfires and wear costumes to ward off roaming ghosts. In recent times the festival is celebrated with activities including dressing up in spooky costumes, trick-or-treating, apple bobbing, carving pumpkins into jack-o'-lanterns and lighting bonfires.
