Chicago, IL – Do all states “fall back” this weekend? Not quite. While most of the United States will turn clocks back one hour at 2 a.m. on Sunday, November 2, 2025, Hawaii and nearly all of Arizona will not.
According to the U.S. Department of Transportation, these are the only two states that have opted out of Daylight Saving Time, keeping standard time year-round. Their decision means no clock changes — and no confusion — each spring and fall.
In Hawaii, the time never changes because the islands’ daylight hours remain consistent year-round due to their tropical latitude. Honolulu, Maui, and the Big Island will stay on Hawaii Standard Time (HST) while the rest of the country “falls back.”
In Arizona, most residents — including those in Phoenix, Tucson, and Flagstaff — also keep clocks unchanged. The state stays on Mountain Standard Time (MST) all year, though one exception exists: the Navajo Nation, located in northeastern Arizona, does observe Daylight Saving Time in sync with neighboring states.
For everyone else, the time change happens this weekend. But whether or not you reset your clocks, fire officials recommend checking smoke and carbon monoxide detectors and replacing batteries — a twice-yearly safety habit that can save lives.
Daylight Saving Time returns for the rest of the country on Sunday, March 8, 2026, but for Hawaii and most of Arizona, the clocks will keep ticking — exactly as they are.
