Millions of Americans will turn their clocks back one hour when Daylight Saving Time (DST) ends on Sunday, November 2, 2025. This shift marks the return to Standard Time, bringing earlier sunsets and lighter mornings.

The time change affects daily routines, energy use, and even health, making it important to prepare in advance.
When does Daylight Saving Time end in 2025?
Daylight Saving Time in the United States began on Sunday, March 9, 2025, with clocks moving forward by one hour. That cycle officially ends at 2:00 a.m. on Sunday, November 2, 2025, when clocks “fall back” by one hour.
After November 2, Standard Time will remain in effect until spring 2026.
Residents can expect darker evenings and lighter mornings—a pattern that often improves rest for many but disrupts routines for others.
A quick history of Daylight Saving Time in the U.S.
The U.S. first introduced Daylight Saving Time during World War I and World War II to conserve energy. Congress later standardized it with the Energy Policy Act of 2005, setting DST to begin on the second Sunday in March and end on the first Sunday in November.
However, not all states observe the time change. Hawaii, most of Arizona, and some U.S. territories like Puerto Rico and Guam stay on Standard Time year-round because their daylight hours remain relatively stable.
Will Daylight Saving Time end permanently?
The future of DST continues to spark national debate. Although some states—including Florida, Washington, California, and Tennessee—have passed laws to stay on permanent Daylight Saving Time, they still need congressional approval.
Critics of DST argue that changing clocks twice a year disrupts sleep cycles, increases fatigue, and leads to higher rates of traffic accidents. Many health experts also say that sticking to one consistent schedule would boost overall wellness and productivity.
Despite the controversy, most Americans will still participate in the biannual time change in 2025.
Expert tips to adjust to the time change
Health experts suggest several ways to ease the transition when clocks move back:
- Shift your sleep schedule early: Start going to bed and waking up 15–30 minutes earlier a few days before the change.
- Limit screen time: Avoid smartphones, TVs, and computers at least one hour before bedtime to reduce blue light exposure.
- Get natural daylight: Spend time outdoors during daylight hours to help regulate your internal clock.
- Stick to a routine: Maintain consistent sleep and wake times, even on weekends, to support your body’s adjustment.
Following these tips can help minimize disruptions to your sleep and energy levels.
