In the United States, Daylight Saving Time (DST) will begin on Sunday, March 9, 2025, at 2 a.m. local time. Clocks will be set forward one hour, meaning longer daylight hours in the evening but one hour less of sleep that night.
When Does Daylight Saving Time End in 2025?
Daylight Saving Time will end on Sunday, November 2, 2025, at 2 a.m. Clocks will be set back one hour, giving people an extra hour of sleep but resulting in earlier sunsets.
Which States Observe Daylight Saving Time?
Most U.S. states participate in Daylight Saving Time, but Hawaii and most of Arizona do not. These states remain on standard time year-round. Some territories, such as Puerto Rico, Guam, the U.S. Virgin Islands, and American Samoa, also do not observe DST.
Will Daylight Saving Time Become Permanent?
The debate over eliminating seasonal clock changes continues:
- In 2022, the Sunshine Protection Act proposed making Daylight Saving Time permanent, but it stalled in Congress and has not been enacted into law.
- Several states, including Texas, Florida, and California, have introduced legislation to abolish the clock changes, but federal approval is required for permanent changes.
As of 2025, no official changes have been made, meaning clock changes will continue for now.
Health Impacts of Daylight Saving Time
Many experts argue that the time change negatively affects health and well-being, including:
- Disrupted Sleep Patterns: The body’s internal clock can take days to adjust after losing or gaining an hour.
- Increased Risk of Heart Issues: Studies show that heart attack rates increase slightly after the spring time change.
- More Car Accidents: Fatigue and darker mornings can lead to an increase in traffic accidents after DST begins.
Because of these concerns, many doctors and researchers advocate for ending seasonal time changes.
How to Adjust to Daylight Saving Time
Here are some tips to make the transition easier:
- Go to Bed Earlier – Start shifting your bedtime 15-20 minutes earlier a few days before the time change.
- Get Morning Sunlight – Exposure to natural light in the morning helps reset your internal clock.
- Limit Screen Time Before Bed – Reduce exposure to blue light from phones and computers before sleeping.
- Be Mindful of Caffeine and Alcohol – These can disrupt sleep quality, making the adjustment harder.
Public Opinion and Future of DST
Polls show that a majority of Americans favor eliminating the biannual clock change and sticking to one time system year-round.
As of now, no official changes have been approved at the federal level, so Daylight Saving Time will continue in 2025. However, with ongoing discussions, the future of permanent DST or standard time remains uncertain.
For now, prepare to spring forward on March 9, 2025, and fall back on November 2, 2025!
