During the Halloween festival, people traditionally carve faces into pumpkins in the US and Canada. Known as Jack-o'-lanterns, this practice stems from ancient Celtic traditions where turnips were originally used. Participants often decorate pumpkins with various designs and light candles inside, creating a spooky atmosphere during the festivities. Halloween involves dressing in costumes, trick-or-treating, and community gatherings, making it a widely celebrated cultural event that combines folklore, creativity, and fun, especially for children.
