Halloween in the United States is traditionally celebrated on October 31 each year. It falls on a Friday in 2025, and the day is widely observed with costumes, trick-or-treating, parties, and other spooky activities. While many people treat it as a festive, non-workday occasion, it is not a federal holiday, so most government offices, banks, and post offices remain open on Halloween except for any local closings or weather-related disruptions. Communities often host Halloween events, parades, and haunted attractions, especially in the weeks surrounding October 31.
