United States Daylight Saving Time Ends

Daylight saving time in the United States is set to end on Sunday, November 2, 2025, at 2 a.m. local time, when clocks will 'fall back' by one hour. This change will result in earlier sunsets and more hours of darkness in the evenings for most of the United States, while providing more daylight in winter mornings. States like United States — Hawaii and United States — Arizona, along with several U.S. territories, do not observe daylight saving time. The practice, which originated during World War I to save fuel, was legally established by the Uniform Time Act of 1966. There is ongoing debate about its elimination, with former President Donald Trump expressing varied opinions on the matter, at times calling it 'inconvenient and very costly to our Nation' and at other times acknowledging it as a '50-50 issue' among the public. The United States passed the Sunshine Protection Act in 2022 to make daylight saving time permanent, but it did not advance in the United States — United States House of Representatives. Studies suggest that the twice-yearly clock change can have negative impacts on public health.
