Halloween, celebrated on October 31st, is a festive occasion marked by costumes, trick-or-treating, and spooky decorations. Originating from the ancient Celtic festival of Samhain, it was believed that on this night, the boundary between the living and the dead was blurred, allowing spirits to roam the earth. Today, Halloween is a time for fun and creativity, with people of all ages dressing up as their favorite characters, from ghosts to superheroes. Communities often host events like haunted houses and pumpkin carving contests, making it a beloved holiday for many around the world.
