Upcoming Halloween dates
Why Halloween is on October 31
Halloween's date is ancient: October 31 aligns with Samhain, the Celtic festival marking the end of harvest, absorbed by the church as the eve of All Hallows' Day (November 1) — hence All Hallows' Eve, contracted over centuries to Halloween. Unlike most old festivals it has grown, not shrunk: it is now the second-largest commercial holiday in the United States after Christmas.
Planning ahead
The costume calendar runs earlier than you think: popular costumes and sizes sell through by mid-October, and group or homemade costumes need lead time for ordering pieces. Pumpkins for carving keep about one to two weeks once cut, so the sweet spot for jack-o'-lanterns is the third week of October. Candy, mercifully, can be bought whenever it is on sale — it outlasts the season.

Is Halloween always on October 31?
Yes — it is fixed to the eve of All Saints' Day (November 1) and never moves, though the day of the week it lands on changes each year and shifts when trick-or-treating happens in some towns.
Where does trick-or-treating come from?
It descends from "souling" and "guising" — medieval British and Irish customs of going door-to-door offering prayers or performances in exchange for food. The phrase "trick or treat" is a 20th-century North American addition, first recorded in the 1920s.
