Trick-or-treating in Chicago and its surrounding suburbs is scheduled to run from 3 p.m. to 7 p.m. on Saturday, Oct. 31, 2026, according to data from FrightMaps.
The holiday falls on a Saturday this year, providing a longer evening window for candy collection than a weekday schedule would allow. NBC Chicago noted that this timing aligns with the typical trick‑or‑treat window previously reported for the area, referencing the FrightMaps website.
