Daylight saving time is a biannual event that affects millions. In 2025, the time change will occur on November 2. As the year progresses, many will prepare to adjust their clocks as we transition back to standard time.

When Do We Adjust the Clocks for 2025 Daylight Saving Time Changes?

The end of daylight saving time in 2025 will take place on Sunday, November 2, at 2 a.m. local time. On this day, clocks will turn back one hour.

This means time will revert from 1:59 a.m. back to 1 a.m. This adjustment allows for more daylight during the winter mornings. Notably, residents of Hawaii, Arizona, and specific U.S. territories will not change their clocks.

Historical Context of Daylight Saving Time

Daylight saving time was introduced in the United States in 1918 through the Standard Time Act. The main goal was to conserve fuel during World War I by harnessing more daylight. Although it was discontinued after the war, it was reintroduced on an emergency basis throughout the 20th century.

In 1966, the Uniform Time Act established a consistent schedule for the time changes. Congress later amended this act in 2005, extending the daylight saving period to begin on the second Sunday of March and end on the first Sunday of November. This modification aimed to promote energy savings.

Future of Daylight Saving Time

There remains ongoing debate about the relevance of daylight saving time. Some lawmakers advocate for a uniform time year-round to eliminate the two annual clock adjustments. Recent discussions in Congress and support from political figures indicate a potential shift in the near future.

Currently, Hawaii and Arizona do not observe daylight saving time, nor do several U.S. territories, including American Samoa and Puerto Rico. There has been interest in revising these practices, but no definitive changes are imminent.

Next Daylight Saving Time Start Date

Looking ahead, daylight saving time will resume on Sunday, March 8, 2026, at 2 a.m. local time. Clocks will move forward by one hour, making the day jump from 1:59 a.m. to 3 a.m. This practice aims to maximize evening daylight.

End Date for Daylight Saving Time 2025: November 2 at 2 a.m.
Start Date for Daylight Saving Time 2026: March 8 at 2 a.m.
Locations Not Observing: Hawaii, Arizona, American Samoa, Guam, Northern Mariana Islands, Puerto Rico, U.S. Virgin Islands.

As discussions about the future of daylight saving time continue, many Americans will prepare to reset their clocks, marking the transition into the darker months of the year.
