Daylight Saving Time 2026: When Clocks Change
US daylight saving time 2026 ends Sunday, November 1 at 2 a.m., when clocks fall back an hour. The rule runs from the second Sunday of March to the first Sunday of November.
The 2026 dates
Per NIST, **2026 daylight saving time runs from March 8 at 2 a.m. to November 1 at 2 a.m.** local time. On November 1, clocks **fall back one hour** — sunrise and sunset shift earlier.[1][2]
The statutory rule — **second Sunday in March to first Sunday in November** — was set by the Energy Policy Act of 2005, per NIST.[1][2]
Per the encyclopedia entry, **Arizona (except the Navajo Nation) and Hawaii** do not observe DST, nor do American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands.[2]
Will the clock changes ever end?
The **Sunshine Protection Act** — which would make DST permanent — passed the Senate in 2022 but died in the House. Per the encyclopedia entry, **a reintroduced version passed the House in 2026, with the Senate yet to act** — so for now, clocks still change on November 1.[2]

Dates and rule cross NIST official + encyclopedia; statutory origin, non-observing states and Sunshine Protection Act status are single-source claims (the Act's 2026 House passage is an evolving item to re-verify near November). | Updated |
