The holiday celebrated on October 31st is Halloween. Originating from ancient Celtic festival Samhain, Halloween marked the end of the harvest season and the beginning of winter. Over time, it evolved into a community-centered holiday characterized by costumes, trick-or-treating, and festive gatherings. Children dress up in various costumes and go from door to door asking for candy, a practice known as trick-or-treating. Halloween decorations often include pumpkins carved into jack-o'-lanterns, spooky themes, and a general air of fun and fright. It is a time for creativity, playfulness, and the celebration of all things eerie, making it a favorite among many.
