Daylight Saving Time 2026: When Does the Time Change This Sunday, March 8

Daylight saving time 2026 is just three days away. This Sunday, March 8, clocks across most of the United States spring forward one hour — and this year the time change falls on the earliest possible date the calendar allows.

When Does the Time Change in 2026

Daylight saving time 2026 begins on Sunday, March 8. At 2 a.m., clocks move forward one hour to 3 a.m. — meaning most Americans lose one hour of sleep.

Because March 1 falls on a Sunday this year, March 8 lands on the second Sunday of the month — the earliest possible date daylight saving time can occur under current federal law.

The standard advice is to change your clocks before going to bed Saturday night, March 7, so you are not caught off guard Sunday morning.

Daylight Savings 2026 End Date: When Do Clocks Fall Back

Daylight saving time ends Sunday, November 1, 2026, at 2:00 a.m., when clocks fall back one hour. Sunrise and sunset will be about one hour earlier, bringing more light in the mornings but darker evenings.

Daylight saving time in the United States lasts a total of 34 weeks, running from early-to-mid March all the way to the beginning of November in states that observe it.

Which States Do Not Observe Daylight Saving Time

Hawaii and most of Arizona do not observe daylight saving time. Arizona opts out because of the state's desert climate. The Navajo Nation, which spans parts of Arizona, Utah, and New Mexico, does participate.

U.S. territories American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands also do not participate in the time change.

Health Risks of the Spring Time Change

The time change can usher in sleep trouble for weeks or longer. Fatal car crashes temporarily jump the first few days after the spring time change, with the risk highest in the morning — researchers attribute this to sleep deprivation.

The American Heart Association points to studies suggesting an uptick in heart attacks on the Monday after daylight saving time begins, and in strokes for two days afterward. Doctors note that the abrupt circadian disruption may worsen factors like high blood pressure in people already at risk.

Adjusting clocks twice a year can also lead to increased risk of mood disturbances and hospital admissions, according to the Johns Hopkins Bloomberg School of Public Health.

Tips to Adjust to Daylight Saving Time 2026

Sleep experts suggest going to bed 10 to 15 minutes earlier each night in the days leading up to the time change. Getting outside early in the morning for natural sunlight helps reset your body clock. Limiting caffeine late in the day and keeping a consistent sleep and meal routine — including on weekends — also eases the transition.

Is Daylight Saving Time Going Away? The Daylight Act of 2026

The debate over whether to end the twice-annual time change is heating up again in Congress. Florida Representative Greg Stube introduced the Daylight Act of 2026, which proposes setting clocks forward 30 minutes in the spring and never changing them again — a compromise between permanent standard time and permanent daylight saving time.

As the debate continues, the annual practice of changing the clocks will continue for the foreseeable future. Most states, the District of Columbia, and the Navajo Nation observe daylight saving time under the current schedule, which has been in place since 2007.

Until Congress acts, set your clocks forward this Saturday night — and enjoy the extra hour of evening daylight starting Sunday, March 8.
