Daylight saving time ends early on November 2, 2025 - how it affects the sleep, sunsets, and what states it observes

The end of the daylight saving time (DST) for 2025 is around the corner, bringing shorter days and longer nights, because watches are set to ‘relapse’. Despite ongoing debate over eliminating the bi-annual clock change, most of the US will re-adjust its watches in November. If the change occurs, the shift of this year will take place at 02:00 on Sunday, November 2, 2025. The change is a day earlier than last year, as DST always ends on the first Sunday in November. The adjustment gives Americans an extra hour of sleep, but it also means earlier sunsets and longer nights. DST will resume on Sunday, March 8, 2026. What is the saving time of daylight? Daylight saving time runs from March to November, when watches are moved an hour in advance to expand the daylight of the evening. In November, watches are put back an hour to bring more daylight to the winter mornings. The ‘spring forward’ shift offering morning light for brighter evenings, while the ‘fall back’ recovered early daylight, but shortened evenings. Who observes and who does not observe every US state or territory. Hawaii and most of Arizona do not participate, with the exception of the Navajo Nation, which extends parts of Arizona, Utah and New Mexico. Arizona, with its warm desert climate, chose after the uniform time law and argued that later sunsets offer little benefit during the hottest months. Five US areas also do not follow DST: American Samoa, Guam, Northern Mariana Islands, Puerto Rico and the US Virgin Islands. Debates continue as critics argue that the bi -annual clock changes disrupt the sleep and offer little practical benefit, attempts to abolish the system still have to succeed at the national level. For now, Americans can prepare to return their watches on November 2 – and enjoy one extra hour of rest.
