October 31st is celebrated as Halloween, a holiday with ancient origins rooted in the Celtic festival of Samhain. This festival marked the end of the harvest season and the beginning of winter, a time when it was believed that the boundary between the living and the dead was blurred. People would light bonfires and wear costumes to ward off ghosts. Over time, Halloween evolved into a more community-centered holiday characterized by activities such as trick-or-treating, costume parties, and pumpkin carving. Today, Halloween is not just for adults; it is celebrated by children and families across many cultures.
