The United States concludes daylight saving time this Sunday, November 2, 2025, when clocks move back one hour at 2 a.m. local time to standard time. This shift applies to most states, affecting around 300 million people, while Hawaii and most of Arizona remain exempt. The change follows the Uniform Time Act of 1966 and aims to better align daylight with daily activities during winter months.
President-elect Donald Trump has voiced strong support for ending the twice-yearly clock adjustments, labeling them inconvenient and costly. In recent statements, he confirmed that Republicans will prioritize related legislation after his January 2026 inauguration. The transition grants residents an extra hour of sleep but leads to earlier sunsets.
This year’s end falls on the earliest possible first Sunday in November, one day ahead of the 2024 date. The practice has run for eight months, starting March 9, 2025.
- 2025 daylight saving start: March 9.
- Duration: eight months.
- Key exemptions: Hawaii, Arizona, Puerto Rico.
Historical roots of the system
Daylight saving time originated in Germany in 1916 to conserve energy during World War I. The US adopted it in 1918, with intermittent use during crises like World War II and the 1973 oil embargo.
Since 2007, the period lasts eight months, beginning on the second Sunday in March and ending on the first Sunday in November. This schedule coordinates with Canada and Mexico to reduce cross-border disruptions.
Economic and safety benefits cited
Research shows extended afternoon daylight reduces crime by up to 7% in well-lit hours. Retail and tourism sectors gain from longer outdoor activity windows, with a 2021 survey finding 58% of Americans favoring later sunsets for evening leisure.
International time alignment supports trade efficiency. Neighboring countries follow similar patterns, minimizing scheduling conflicts in business and logistics.
Critics note minimal energy savings, as reduced lighting use is offset by higher air conditioning demands. Annual productivity losses from transitions reach billions, per congressional studies.

Health and opposition arguments
The American Academy of Sleep Medicine reports a 6% rise in traffic accidents after spring transitions due to sleep disruption. Sleep experts advocate permanent standard time to maintain natural circadian rhythms.
Trump reiterated his stance in March 2025, acknowledging split public opinion. A 2021 poll showed 75% of Americans oppose biannual changes.
Nearly 30 states are debating an end to switches, contingent on federal approval. Florida and Texas lead efforts for permanent daylight saving through local laws.
Current legislative momentum
The Sunshine Protection Act, unanimously passed by the Senate in 2022, seeks permanent daylight saving but stalled in the House over preferred time choice. By 2025, it has 45 bipartisan co-sponsors, with Trump endorsing it in April.
Western states like Oregon and Washington pursue regional permanent daylight saving blocs. The European Commission discusses similar abolition, targeting 2027 under Poland and Lithuania’s lead.
Public consultations in 2024 found 62% support ending changes. Republican congressional control in 2026 may accelerate votes.
Daily routine adjustments
The fall transition shifts work, school, and public transit schedules, with 40% of workers reporting fatigue in the first weeks, per a 2023 study. International airports like New York’s see increased confusion on transatlantic flights.
Tech companies automatically update systems. Cross-border trade with the US requires annual adaptation guides.
The next daylight saving start is set for March 8, 2026. Polar regions experience up to 24 hours of darkness in December, while the continental US shortest day is December 21.
