Each spring, millions of Americans adjust their clocks forward by one hour, sacrificing a bit of sleep in exchange for longer evenings. It’s a routine that sparks nationwide debate every year—should we continue changing time, or adopt permanent daylight saving? For now, this tradition persists, and the next shift is approaching. In 2026, Daylight Saving Time (DST) will take effect once again, ushering in later sunsets and heralding the unofficial start of spring routines across the United States.
The process may be familiar, but the details still trip people up. What’s the exact date this year? Which states follow it? And why do we even do it in the first place? This article breaks everything down, from the official 2026 DST start date to the historical context, local exceptions, and potential changes on the horizon. Whether you love or loathe losing an hour, being informed will help you plan better and adjust your household smoothly this year.
Key details for Daylight Saving Time 2026
| Event | Start of Daylight Saving Time 2026 |
|---|---|
| Date | Sunday, March 8, 2026 |
| Time | 2:00 AM local time (clocks spring forward to 3:00 AM) |
| Applies to | Most U.S. states and territories |
| Opt-out states | Arizona (except Navajo Nation), Hawaii, U.S. territories (e.g., Puerto Rico) |
When exactly to change your clock in 2026
In 2026, Daylight Saving Time begins on Sunday, March 8. At exactly 2:00 a.m. local time, clocks will move forward one hour to 3:00 a.m., effectively “losing” one hour of sleep. While most smartphones and internet-connected devices will update automatically, it’s still important to double-check analog clocks, car dashboards, kitchen appliances, and wall clocks to ensure they’re adjusted accordingly.
Many people follow a best practice of setting clocks ahead before bedtime on Saturday night (March 7) so they wake up on Sunday already aligned with the new time. This transition also serves as a useful reminder to update batteries in smoke and carbon monoxide detectors—another semiannual safety ritual tied closely to the time change.
Why most Americans still observe Daylight Saving Time
The concept of Daylight Saving Time has been around since World War I, but it wasn’t until 1966 that the U.S. passed the Uniform Time Act, standardizing the start and end dates across states that choose to observe it. The main theory behind DST is to reduce energy consumption by making better use of natural daylight in the evenings, particularly during warmer months.
However, this rationale has been hotly debated. Multiple studies suggest the energy savings are minimal, while health experts argue that losing an hour of sleep can disrupt circadian rhythms, leading to short-term increases in traffic accidents, heart attacks, and workplace injuries. Despite the controversy, the annual spring-forward event continues largely unchanged due to Congressional inaction and reluctance to amend the established framework on a federal level.
Which states and regions don’t observe it
While most states follow the federally mandated DST schedule, some areas remain on standard time year-round. These include:
- Arizona — Except for the Navajo Nation, which does observe DST
- Hawaii
- U.S. territories — Including Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands
The decision to abstain is largely due to geography and climate. For instance, Hawaii’s proximity to the equator yields little variation in daylight hours year-round, making DST unnecessary. In Arizona, additional daylight in the summer only exacerbates high temperatures, so the state opted to remain on standard time permanently back in the 1960s.
Comparing the pros and cons of DST
| Winners | Losers |
|---|---|
| Evening athletes & outdoor enthusiasts (more light in evening hours) | Early risers who lose morning daylight |
| Retailers and restaurants (more post-work foot traffic) | Parents of young children (bedtime disruptions) |
| Tourism industry and local economies | Night-shift workers & healthcare professionals |
What might change in the future
In recent years, there’s been a significant push to eliminate the biannual clock change altogether. Numerous states have passed legislation proposing to remain on DST permanently. A 2022 proposal known as the Sunshine Protection Act gained traction in Congress but ultimately stalled. If passed, this act would make Daylight Saving Time permanent, eliminating the need to “fall back” in November.

However, enacting such changes on a national scale remains complicated. Under current federal law, states can opt out of DST (like Arizona and Hawaii have), but they cannot independently choose to adopt DST full-time without permission from Congress. Thus, pending further legislative action, the current pattern will likely persist for the foreseeable future.
How to better adapt to the time change
For many people, the spring transition can cause disruptions in sleep and productivity. Fortunately, there are steps you can take to make the change easier:
- Start adjusting bedtime gradually in the week leading up to DST—go to bed 15 minutes earlier each night.
- Avoid caffeine and screens in the hour before bedtime.
- Get outside in the morning sunlight on the Sunday after the time change to reset your internal clock.
- Stay hydrated and avoid heavy meals late at night during the transition week.
- Monitor children’s sleep schedules and try to keep mealtimes consistent.
These small lifestyle adjustments can ease the biological stress associated with “springing forward” and help your household adjust more comfortably to the new rhythm.
Reasons Daylight Saving Time remains controversial
Despite public familiarity, DST remains one of the most debated time-related policies in the U.S. Polls indicate that a growing share of Americans want to eliminate the twice-yearly shift. But there’s no clear consensus on whether to remain on standard time or daylight time permanently.
Those in favor of DST cite the benefits of longer summer evenings, while opponents point to the negative consequences to public health and safety. The medical community especially has raised concerns. The American Academy of Sleep Medicine has recommended eliminating DST transitions and favoring permanent standard time instead.
“Even a one-hour time change can elevate cardiovascular risk and lead to reduced workplace efficiency.”

Still, absent federal intervention, DST changes will continue as scheduled in 2026 and beyond.
FAQs about Daylight Saving Time 2026
When does Daylight Saving Time begin in 2026?
Daylight Saving Time begins on Sunday, March 8, 2026, at 2:00 a.m. Clocks spring forward to 3:00 a.m.
Do all states observe DST?
No. Arizona (except the Navajo Nation), Hawaii, and most U.S. territories do not observe Daylight Saving Time.
Does my smartphone adjust automatically?
Yes. Most smartphones, tablets, and smartwatches will update the time automatically, provided they have the correct time zone settings and internet access.
Will the U.S. ever eliminate DST?
Possibly. Legislation like the proposed Sunshine Protection Act has aimed to make DST permanent, but it has not yet passed Congress.
Why do we change clocks at 2:00 a.m.?
The early morning time is chosen to minimize disruption. Few people are working or traveling at that hour, and it avoids calendar date confusion.
Does Daylight Saving Time save energy?
The original idea was to reduce energy use, but modern research shows minimal impact due to changes in technology and lifestyle.
Is the time change bad for health?
Studies have linked the spring time change to short-term risks like sleep disruption, heart attack, and workplace accidents.
How can I make the transition easier?
Begin adjusting your sleep schedule gradually in the week before DST starts and get plenty of morning sunlight after the switch.
