As 2026 approaches, millions of Americans are once again preparing for the biannual clock change that signals the start and end of Daylight Saving Time (DST). This seasonal adjustment, while routine for many, still causes confusion regarding specific dates and the implications for health, public safety, energy use, and scheduling. Whether you’re a commuter, parent, business owner, or simply someone who values sleep, understanding exactly when and why these changes occur can help you better plan for the year ahead.
Daylight Saving Time is a long-standing tradition in most parts of the United States. First established during World War I to conserve energy, it has evolved over time, with Congress last modifying the schedule in 2007. Despite continued debates over its usefulness, the system remains in place. In 2026, DST begins and ends on its usual schedule — the second Sunday in March and the first Sunday in November, respectively — and it’s important to be prepared for the subtle but impactful alteration of our collective routines.
Key facts about DST changes in 2026
| Detail | Date & Description |
|---|---|
| DST Start Date | Sunday, March 8, 2026 — clocks spring forward 1 hour at 2:00 AM local time |
| DST End Date | Sunday, November 1, 2026 — clocks fall back 1 hour at 2:00 AM local time |
| Time Shift Impact | Loss of 1 hour in March; gain of 1 hour in November |
| Observed In | Most of the United States, except Hawaii and most of Arizona |
| Legislation | Energy Policy Act of 2005 governs current DST schedule |
What changed this year
Unlike some previous years where political discussions caused uncertainty around possible permanent daylight saving time legislation, 2026 features no changes in the federal law. As of now, states are required to adhere to the standardized DST start and end dates unless Congress amends federal statutes. A few states have passed local resolutions to remain on DST year-round, but without federal approval, those efforts remain symbolic.
The March 8 and November 1 switch marks a return to the familiar pattern, giving businesses, schools, and transportation agencies a predictable template to follow. However, growing public sentiment in favor of abolishing the biannual clock change suggests that this may not be the case forever.
Why Daylight Saving Time exists
The concept was first widely implemented during war times to reduce the need for artificial lighting and save fuel. Over the decades, the scope of DST has shifted to align more with economic and social routines. Today, it is often justified by its supposed benefits for retail sales, traffic safety, and lifestyle alignment to daylight hours.
Still, there is ongoing debate among scientists, lawmakers, and the public about whether the advantages outweigh the drawbacks. Sleep disruption, health consequences, and scheduling confusion continue to be major points of contention. Despite strong opinions on both sides, federal action to remove DST remains minimal — for now.
States that do not observe DST
Currently, only two U.S. states remain exempt from DST: Hawaii and most of Arizona (excluding the Navajo Nation, which does observe it). These states opted out due to their geographic location and consistent daylight patterns throughout the year.
U.S. territories such as Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands also do not observe DST. For residents in these regions, the clock remains unchanged in March and November.
Impacts on health and well-being
Medical experts and sleep researchers have continually flagged the risks associated with the time shift. The transition in March, when we “spring forward,” is particularly problematic, linked to increased rates of heart attacks, traffic accidents, and workplace injuries following the switch.
Research has consistently shown a spike in heart-related emergencies within days of the spring transition. Temporary sleep loss affects cardiovascular health in profound ways.

Conversely, the “fall back” in November may feel like a relief, but it too has consequences, including disruption of circadian rhythms and an increased rate of depressive episodes due to earlier sunsets. The more we learn about our biological clocks, the clearer it becomes that even a one-hour adjustment can have significant side effects.
Public opinion and policy debates
Over 70% of Americans surveyed in recent years favor abolishing the twice-a-year clock change. Lawmakers in several states, including Florida, California, and Washington, have proposed legislation to make DST permanent. However, under current federal law, such changes cannot be enacted unilaterally due to the Uniform Time Act, which only allows states to opt out of DST altogether—not to make it year-round without federal permission.
The biannual clock shift is outdated and unpopular. Congress must modernize our time policies to reflect what science and voters are telling us.

In 2022, the U.S. Senate passed the Sunshine Protection Act, aiming to make DST permanent nationwide. However, as of 2026, the bill has not yet been passed by the House of Representatives and signed into law. Until then, the scheduled time change remains a national standard.
How to prepare for DST changes
Adapting to daylight saving time can be smoother with a bit of preparation. Here are several tips to reduce the impact on your body and your schedule:
- Gradually adjust your sleep schedule 15-30 minutes earlier or later (depending on the season) starting a few days ahead of the change.
- Increase exposure to natural light in the morning to reset your internal clock more quickly.
- Avoid caffeine and heavy meals right before bedtime leading up to the date change.
- Double-check time settings on smartphones, alarm clocks, and appliances, which may not adjust automatically.
- Plan travel and work commitments with awareness of the upcoming time change, especially in March.
Business and travel implications
Industries that rely heavily on synchronization — such as aviation, broadcasting, and global finance — pay close attention to DST changes. Airlines, in particular, must adjust thousands of flight schedules to account for the shift, ensuring minimal confusion for travelers crossing time zones.
Businesses with remote teams across multiple states (or countries) also need to be vigilant, especially during the weeks surrounding the switch. Misalignment can create missed meetings, delayed responses, and reduced efficiency if teams are not briefed in advance.
Every year, we see confusion in multinational scheduling due to time changes. Having clear, company-wide reminders helps reduce errors in global operations.
