When is Halloween celebrated every year?

Halloween is celebrated every year on October 31st. The date marks the evening before All Saints’ Day (November 1st) and has deep roots in ancient traditions. Over time, it evolved from sacred rituals to a global festival focused on costumes, spooky fun, and community gatherings. Today, it’s observed in many countries, especially in the United States, Canada, and the United Kingdom, with people decorating homes, hosting parties, and enjoying “trick-or-treating.”
