Halloween, celebrated on October 31, is a festival rooted in ancient traditions, primarily the Celtic festival of Samhain. It marked the end of the harvest and the beginning of winter, a time when the boundary between the living and the dead was believed to blur. Over time, Halloween has evolved into a more secular celebration, characterized by activities like trick-or-treating, costume-wearing, pumpkin carving, and haunted attractions. The holiday blends elements of folklore, superstition, and community fun, making it one of the most popular and culturally rich events observed in many countries around the world.
