Prepare for the end of daylight saving time: Key information on the fall back and how to get ready

The end of daylight saving time allows people to adjust their clocks, gaining an extra hour of sleep. This annual shift back, known as “falling back,” is designed to offer more morning daylight during winter months.
Key Information on the End of Daylight Saving Time
When Does Daylight Saving Time End?
In 2025, daylight saving time concludes at 2 a.m. on November 2. Clocks should be set back one hour on the evening of November 1.
Preparing for the Time Change
- Adjust sleep schedules gradually before the change.
- Reduce exposure to bright light after dark.
- Engage in regular exercise to aid sleep.
- Maintain a consistent bedtime routine, avoiding caffeine and alcohol.
Why Do We Fall Back?
The concept, traced back to World War I in Germany and Britain, aims to optimize daylight use. By turning clocks back, mornings receive more natural light, with sunrise in December between 7:04 a.m. and 7:23 a.m.
Daylight Saving Time Observance
Not all U.S. states and territories adhere to daylight saving time. Hawaii and most of Arizona, alongside territories like American Samoa and Puerto Rico, do not participate. Arizona’s decision stems from avoiding an extra hour of daylight during hot months, while Hawaii’s proximity to the equator keeps sunlight hours relatively constant.
Global Practices
Daylight saving time is utilized globally, including countries across North America, Europe, and parts of Asia in the Northern Hemisphere summer, as well as regions in South America and Oceania in their summer months.
Future Considerations
The discussion on making standard time permanent remains in political discourse. Despite a Senate approval in 2022 to eliminate seasonal time changes permanently, the proposal has yet to pass through the House. Proponents argue it could simplify timekeeping and avoid abrupt seasonal adjustments.
