Halloween, celebrated on October 31st, is a holiday with ancient origins 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 became blurred. Halloween traditions include trick-or-treating, where children dress in costumes and go door-to-door collecting sweets, and carving pumpkins into jack-o’-lanterns. The modern celebration of Halloween also features haunted houses, costume parties, and spooky decorations. Despite its pagan roots, Halloween has been embraced in many countries, evolving into a festive occasion enjoyed by people of all ages.
