Americans will gain an extra hour of sleep Sunday as Daylight Saving Time ends for 2026. The annual clock change is once again raising questions about whether the United States should continue switching between daylight saving time and standard time.

At 2 a.m. Sunday, Nov. 1, clocks in most of the country will move back one hour to 1 a.m., bringing brighter mornings and earlier sunsets as winter approaches.

The seasonal adjustment comes as Congress remains divided over efforts to eliminate the twice-yearly clock changes. The U.S. House has approved legislation that would make daylight saving time permanent, but the measure remains stalled in the Senate despite President Donald Trump's support.

What Is Daylight Saving Time?

Daylight Saving Time is the seasonal practice of moving clocks forward one hour during part of the year to shift an hour of daylight from the morning to the evening.

In the United States, daylight saving time begins on the second Sunday in March. Clocks move forward from 2 a.m. to 3 a.m., meaning people lose an hour that night.

The period ends on the first Sunday in November, when clocks move backward from 2 a.m. to 1 a.m. The repeated hour gives people an additional hour on the clock and returns the country to standard time.

The practice is commonly summarized by the expression "spring forward, fall back."

The purpose is to make better use of available daylight during warmer months, particularly by providing more sunlight during late afternoon and evening hours. It does not create additional daylight. Instead, it changes how daylight hours align with people's schedules.

For 2026, daylight saving time began March 8 and ends Nov. 1. Under the existing federal schedule, clocks will move forward again March 14, 2027.

Why Are Americans Changing Their Clocks?

The United States has used seasonal clock adjustments for more than a century, although the policy has changed several times.

Germany introduced daylight saving time in 1916 during World War I as a way to conserve fuel and energy. The United States followed in 1918 with the Standard Time Act, which also established the country's standard time zones.

The original American experiment proved unpopular. Congress repealed the national daylight saving requirement in 1919 over President Woodrow Wilson's veto, leaving local governments to determine their own schedules.

The practice returned during World War II. In 1942, the federal government established year-round daylight saving time, known as War Time, to support wartime energy conservation.

After the war, inconsistent local schedules created confusion for transportation companies and travelers.

Congress addressed the problem through the Uniform Time Act of 1966, establishing a more consistent national framework while allowing states to opt out of daylight saving time.

The current schedule was established through the Energy Policy Act of 2005 and took effect in 2007.

When Will Clocks Change Again?

The 2026 fall adjustment takes place Sunday, Nov. 1, at 2 a.m. local time.

The next scheduled clock adjustment will occur in March 2027.

Important dates include:

• March 8, 2026: Daylight saving time began.

• Nov. 1, 2026: Clocks move back one hour.

• March 14, 2027: Daylight saving time is scheduled to resume.

Most smartphones, computers and other internet-connected devices automatically update their clocks. However, people with traditional clocks, appliances and some vehicle systems may need to make the adjustment manually.

Where Will the Sun Set Earliest?

The return to standard time means earlier sunsets across the country, although the impact varies by geographic location.

Northern communities generally experience more noticeable seasonal changes in daylight than cities farther south.

According to the weather information cited in the original report, Caribou, Maine, is expected to experience sunset around 4:16 p.m. Sunday.

Other cities will also see earlier darkness:

• New York City: Before 5 p.m.

• Chicago: Before 5 p.m.

• Denver: Before 5 p.m.

• Seattle: Before 5 p.m.

• Houston: Approximately 5:34 p.m.

• Miami: Approximately 5:39 p.m.

The difference becomes more noticeable as winter approaches. Northern cities such as Seattle experience a larger reduction in daylight during November than southern communities such as Austin and Tampa.

Congress Debates Making Daylight Saving Time Permanent

The annual clock adjustment has renewed calls to eliminate the practice altogether.

In July 2026, the House of Representatives passed the Sunshine Protection Act, legislation that would make daylight saving time permanent nationwide.

The proposal received bipartisan support, but it has encountered significant resistance in the Senate.

President Trump has publicly supported eliminating the twice-yearly changes, arguing that Americans would benefit from additional evening sunlight.

However, opponents say permanent daylight saving time would create darker winter mornings, particularly in northern states.

Republican Sen. Tom Cotton of Arkansas has warned that later winter sunrises could create problems for children traveling to school and people commuting to work.

Sen. Mike Rounds, R-South Dakota, has also expressed concerns about students beginning their school days before sunrise.

Senate Majority Leader John Thune indicated that there is no clear path forward for the legislation.

The Associated Press reported that senators were unlikely to act before the end of the year, leaving the existing system in place for the Nov. 1 adjustment.

Why Is Permanent Daylight Saving Time Controversial?

The debate is not simply about whether Americans want more sunshine. It also involves sleep schedules, public safety, economic activity and the effects of natural daylight on the human body.

Supporters of permanent daylight saving time argue that longer evenings would give families more opportunities for outdoor activities, shopping, recreation and social events after work.

They also contend that eliminating the seasonal clock adjustment would reduce disruptions to daily routines.

Opponents argue that permanent daylight saving time would shift daylight away from early mornings, potentially leaving children, commuters and workers traveling in darkness during winter.

Sleep researchers have raised another concern: permanent standard time may better align with the body's natural circadian rhythm, which is influenced by exposure to morning light.

The American Academy of Sleep Medicine has supported permanent standard time rather than permanent daylight saving time.

This disagreement explains why eliminating the clock changes has proved more complicated than simply passing legislation to keep the clocks forward or backward.

What Do Americans Think About Ending the Clock Changes?

Public opinion polling suggests that many Americans would prefer to stop changing their clocks twice a year.

A March 2026 YouGov survey cited in the original report found that 64% of respondents favored eliminating the twice-yearly clock adjustments, while 16% preferred keeping the current system.

However, support for ending the clock changes does not necessarily mean Americans agree on which time system should replace it.

Some prefer permanent daylight saving time because of the additional evening sunlight. Others favor permanent standard time because of its alignment with morning daylight.

That distinction remains central to the congressional debate.

Which States Do Not Observe Daylight Saving Time?

Most U.S. states participate in daylight saving time, but there are exceptions.

Hawaii and most of Arizona remain on standard time throughout the year.

Hawaii's proximity to the equator means seasonal differences in daylight are relatively small, making the clock adjustment less useful.

Arizona also avoids daylight saving time, partly because of its hot climate. Keeping standard time helps prevent additional evening sunlight during the hottest months.

The Navajo Nation is an exception within Arizona. Because its territory extends across Arizona, New Mexico and Utah, it observes daylight saving time to maintain consistent timekeeping across its communities.

U.S. territories including Puerto Rico, Guam, the U.S. Virgin Islands and American Samoa also do not observe daylight saving time.

What Happens Next?

Unless Congress changes federal law, Americans will continue following the existing daylight saving time schedule.

The Senate has not advanced the Sunshine Protection Act, and the Nov. 1 clock adjustment will proceed as scheduled.

For millions of Americans, the immediate result will be an additional hour on Sunday morning, followed by earlier sunsets throughout the coming months.

The broader debate, however, is far from settled. Lawmakers must still decide whether the country should retain its current system, adopt permanent daylight saving time or move to permanent standard time.

Until that decision is made, Americans will continue the familiar routine of springing forward and falling back.
