Daylight Saving Time 2026: When Did Clocks Spring Forward?

Most Americans “sprang forward” early Sunday, March 8, losing an hour of sleep as daylight saving time officially began. The annual shift, a practice steeped in history and ongoing debate, means evenings will be brighter, but mornings a bit darker for the next several months. The time change took effect at 2:00 a.m. Local time, jumping clocks ahead to 3:00 a.m.

A History of Shifting Time

The practice of daylight saving time isn’t new. It first took hold in the United States during World War I, in 1918, as a way to conserve fuel. According to the Congressional Research Service, the idea resurfaced during World War II, again with the aim of bolstering national security. While the specifics have changed over the decades, the core concept – shifting daylight hours – has remained consistent.

The start date for daylight saving time has been a moving target. For two decades before 2007, the switch occurred on the first Sunday in April. Prior to 1987, the Uniform Time Act of 1966 designated the last Sunday in April as the start date. There was even a period in the 1970s, during the energy crisis, when the U.S. Experimented with year-round daylight saving time, beginning in January 1974. That experiment proved short-lived, with a return to standard time in October of the same year and a subsequent shift back to a late-February start in 1975.

How Does It Work in 2026?

Currently, the U.S. Observes daylight saving time for 34 weeks, roughly 65% of the year. This year, the shift means sunrise in Boston, for example, moved from 6:09 a.m. On Saturday, March 7, to 7:08 a.m. On Sunday, March 8. Sunset similarly shifted, from 5:41 p.m. To 6:42 p.m., according to the National Weather Service. The U.S. Naval Observatory serves as the official source of time for the Department of Defense and confirms the second Sunday in March as the standard start date since 2007.

Lost Hour, Lingering Questions

For most of the country, the clock jump means a lost hour of sleep. But the debate over whether that lost hour is worth the benefits continues. While initially intended to conserve energy, a 1974 Transportation Department study found minimal benefits in terms of energy conservation, traffic safety, or reducing violent crime, as reported by the Congressional Research Service. A more recent Energy Department study, following the 2007 start date change, found only a 0.03% reduction in electricity consumption. Some studies have also linked the time shift to negative health effects.

Who Doesn’t Participate?

Not everyone in the U.S. Participates in daylight saving time. Hawaii and Arizona (with the exception of the Navajo Nation) remain on standard time year-round. The territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands also do not observe the time change.

Will It Last? The Push for Permanent Daylight Saving Time

The future of daylight saving time remains uncertain. In 2022, the Senate passed the Sunshine Protection Act, which would have made daylight saving time permanent nationwide. Although, the bill stalled in the House of Representatives and did not become law. The debate centers around potential benefits to public health, safety, and the economy, but also concerns about disrupting established routines and potential negative impacts on certain industries.

Keeping Your Devices Synced

Fortunately, most modern devices automatically adjust for daylight saving time. Apple, Google, and Samsung all offer support pages to help users troubleshoot any time-related issues on their devices. Mobile carriers like Straight Talk and Tracfone also provide instructions for updating the time on Motorola phones.

Looking Ahead: When Does Daylight Saving Time Conclude?

Mark your calendars: the “fall back” to standard time is scheduled for Sunday, November 1, 2026, at 2:00 a.m. Local time. That’s when clocks will be turned back one hour, giving everyone an extra hour of sleep and shifting more daylight to the morning hours. By then, the country will be well into fall, following the autumnal equinox on September 22.
