For anyone planning their schedule, travel, or just trying to avoid showing up an hour late, the crucial question of “when does the time change in the United States?” is a biannual headache. As of the current date, December 17, 2025, the US remains firmly entrenched in the practice of Daylight Saving Time (DST), meaning the clocks will change twice in 2026 according to the established federal guidelines.
The time change in the United States is governed by the Energy Policy Act of 2005, which dictates that DST begins on the second Sunday in March and ends on the first Sunday in November. This article provides the definitive dates for the 2026 time shifts, explains the ongoing legislative battle to end the practice permanently, and lists the specific states and territories that have opted out of the clock-changing ritual entirely, providing a complete picture of the American time landscape.
The Definitive 2026 US Daylight Saving Time Schedule
Understanding the precise dates for the biannual time shift is essential for seamless coordination across the country's various time zones. The dates for 2026 follow the long-standing federal schedule, providing clarity for the Eastern Time Zone, Central Time Zone, Mountain Time Zone, and Pacific Time Zone.
When to "Spring Forward" in 2026 (Loss of an Hour)
The transition to Daylight Saving Time—popularly known as "spring forward"—is when the US moves its clocks ahead by one hour, effectively "stealing" an hour of sleep but providing more daylight in the evenings. This change shifts the country from Standard Time to DST.
- DST Begins (Spring Forward): Sunday, March 8, 2026.
- The Change: Clocks move forward from 2:00 A.M. to 3:00 A.M. local time.
- Effect: Sunrise and sunset will occur one hour later than the previous day.
This date marks the start of the summer season’s extended evening daylight, a practice originally intended to conserve energy, though its modern effectiveness is a subject of intense debate among economists and public health experts.
When to "Fall Back" in 2026 (Gain of an Hour)
The end of Daylight Saving Time—known as "fall back"—returns the country to Standard Time, restoring the lost hour of sleep and shifting daylight back to the morning hours. This is the official conclusion of DST for the year.
- DST Ends (Fall Back): Sunday, November 1, 2026.
- The Change: Clocks move back from 2:00 A.M. to 1:00 A.M. local time.
- Effect: Sunrise and sunset will occur one hour earlier than the previous day.
The return to Standard Time is often welcomed by those who prefer brighter mornings but is criticized by others who dislike the sudden loss of evening daylight, which can impact after-work activities and retail sales.
The Permanent Time Debate: The Sunshine Protection Act and Stalled Legislation
The most current and pressing update regarding the time change in the US is the ongoing, yet stalled, legislative effort to abolish the biannual shift and make Daylight Saving Time permanent across the nation. This movement reflects a growing public and political frustration with the disruption caused by changing the clocks.
The Status of the Sunshine Protection Act
The push for permanent DST is primarily championed by the Sunshine Protection Act. In a significant but ultimately temporary victory, the U.S. Senate unanimously passed a version of this bill in 2022. However, despite this initial momentum, the bill stalled in the House of Representatives and failed to reach the President's desk.
New versions of the bill, such as the 2025 Sunshine Protection Act, have been reintroduced in Congress by bipartisan lawmakers, including Senator Rick Scott and Representative Vern Buchanan. These efforts aim to make DST the year-round standard, effectively ending the "fall back" process forever. However, as of late 2025, a consensus has not been reached, and the biannual change remains the law of the land.
The debate is split between those who support permanent DST for economic and public safety reasons and those who argue for permanent Standard Time, citing better alignment with the body's natural circadian rhythm and the undesirability of sunrises as late as 8:30 A.M. or 9:00 A.M. in the winter months in northern states.
Why Federal Law is Required
While many states have passed their own bills to adopt permanent DST, the Uniform Time Act of 1966, a piece of federal legislation, prohibits states from observing Daylight Saving Time year-round. States are only permitted to either observe the federal DST schedule or opt out entirely and remain on Standard Time permanently (as Arizona and Hawaii have done). Therefore, for the majority of the country to adopt permanent DST, a federal law like the Sunshine Protection Act must be passed and enacted.
The US Time Exceptions: States That Never Change Their Clocks
A common misconception is that all 50 states participate in the time change. In reality, a handful of states and territories do not observe Daylight Saving Time, remaining on Standard Time throughout the entire year. This is a crucial distinction for travelers and businesses operating across state lines.
Arizona: The Desert Exception
The state of Arizona, with the notable exception of the Navajo Nation (which does observe DST to align with neighboring states), opted out of Daylight Saving Time in 1968.
The primary reason is the intense desert heat. During the summer, Arizona residents prefer to have the sun set earlier, allowing for cooler evening temperatures and more comfortable outdoor activities. Moving the clock forward would simply extend the period of intense heat into the late evening, making DST counterproductive to the state's lifestyle and energy conservation goals.
Hawaii: The Tropical Exception
Hawaii is the second major US state that does not observe DST. Its proximity to the equator means there is very little variation in the length of daylight throughout the year, making the practice of shifting the clocks unnecessary and offering negligible benefit.
US Territories
In addition to Arizona and Hawaii, several US territories also remain on Standard Time year-round. These include:
- American Samoa
- Guam
- Northern Mariana Islands
- Puerto Rico
- The Virgin Islands
This means that when the rest of the country "springs forward" in March 2026, these areas will suddenly be one hour "behind" their DST counterparts, and when the country "falls back" in November 2026, the time difference will return to its Standard Time difference.
The History and Impact of Daylight Saving Time
To gain a full understanding of the US time change, it is helpful to review the historical context and the modern-day impacts of this century-old practice.
A Brief History of DST
The concept of Daylight Saving Time was first proposed in the late 19th century but was formally adopted in the US during World War I in 1918 as a measure to conserve fuel for the war effort. It was repealed after the war but reinstated during World War II, again for energy conservation.
The modern, standardized system was established by the Uniform Time Act of 1966, which aimed to create consistency across the nation. The dates were later extended by the Energy Policy Act of 2005, which is the current law dictating the second Sunday in March to the first Sunday in November schedule.
The Modern-Day Debate: Health and Economy
While the original intent was energy savings, many modern studies suggest the energy benefit is minimal or even non-existent. The current debate centers on two main areas:
- Public Health: The time change has been linked to negative health outcomes, including a temporary increase in heart attacks, strokes, and traffic accidents immediately following the "spring forward" shift due to sleep deprivation and disruption of the natural circadian rhythm. Sleep experts and the American Academy of Sleep Medicine often advocate for permanent Standard Time, arguing it is more aligned with human biology.
- Economic Impact: Proponents of permanent DST argue that extra evening daylight boosts the economy by encouraging more after-work shopping, dining, and outdoor recreation, benefiting sectors like retail, tourism, and sports.
In summary, while the political and public debate rages on with the potential for the Sunshine Protection Act to pass in the future, the time change in the United States for 2026 is locked in. Be sure to mark your calendars for the "spring forward" on Sunday, March 8, 2026, and the "fall back" on Sunday, November 1, 2026, unless you reside in the non-observing states of Arizona or Hawaii.
