Halloween is known for its spooky costumes, pumpkin carving, and trick-or-treating, but have you wondered about its origins? Halloween, celebrated every year on October 31, originated from the ancient Celtic festival of Samhain. The Celts believed that on this day, the boundary between the living and the dead blurred, and the dead would come back to cause trouble. Interestingly, Halloween is not only an American phenomenon. In Mexico, for example, they celebrate "El Dia de los Muertos" or "The Day of the Dead" around the same time. This holiday, unlike Halloween, is a time to remember and honor loved ones who have passed. In recent years, Halloween has become a heavily commercialized event. In fact, it is the second largest commercial holiday after Christmas in the United States. This commercialization, while boosting the economy, has also sparked debates about the loss of cultural significance of the holiday.
