Daylight saving time 2025: When do clocks spring forward?
The days are getting longer, and in days millions of people across the United States will see the clocks change as daylight saving time begins.
Cleveland Clinic’s Dr. Alicia Roth was live on the AccuWeather Network on March 6 to discuss how the body is impacted by the time change, which will occur on Sunday, March 9.
Days are growing longer across North America with some areas gaining more than an hour of sunlight throughout March. The longer, brighter days are a prelude to the annual ritual of daylight saving time, which is fast approaching for many across the United States.
When does daylight saving time start?
Clocks will spring forward one hour this Sunday, March 9, 2025, as daylight saving time begins across most of the United States. This will result in later sunrises and sunsets.
Hawaii and Arizona, with the exception of the Navajo Nation located in Arizona, New Mexico and Utah, are the only states that do not observe the biannual time shift and remain in standard time year-round.

Several states have proposed laws to end the practice of changing clocks twice a year, but the legislation has yet to go into effect. The Sunshine Protection Act has also been introduced by lawmakers in the nation's capital, but the bill has not passed the Senate and House of Representatives to make it to the president's desk where it can be signed into law.

When does daylight saving time end?
Daylight saving time will last for nearly nine months, ending on Nov. 2, 2025. On this date, clocks will fall back one hour, and the entire country will once again be in standard time.
Most people are in favor of sticking to either standard time or daylight saving time throughout the entire year, but there is some debate as to which one to stick with permanently. There are benefits and drawbacks to both, with impacts ranging from health dangers to economic influences and personal preferences.
