Every autumn, as the U.S. transitions from October to November, a familiar ritual unfolds—the end of Daylight Saving Time (DST). It’s that time when clocks are set one hour backward, marking the shift from long summer evenings to shorter winter days. Although smartphones and computers adjust automatically, traditional wall clocks and routines can leave many feeling slightly disoriented for a few days

What Exactly Is Daylight Saving Time?
Daylight Saving Time was designed to make better use of daylight during the longer summer months. The idea first gained traction through the Standard Time Act of 1918, but it was officially established under the Uniform Time Act of 1966.
Each year, Americans “spring forward” by setting clocks ahead one hour on the second Sunday in March, and “fall back” by setting them one hour back on the first Sunday in November.
For 2025, DST began on March 9 and will end on November 2. At 2 a.m., clocks will roll back to 1 a.m., granting everyone an extra hour of rest but also signaling earlier sunsets and darker evenings.
Why Was DST Introduced?
The main goal behind Daylight Saving Time was energy conservation. By extending daylight into the evening hours, people would use less electricity for lighting and enjoy more outdoor activities after work.
However, as technology evolved, the effectiveness of this practice has been called into question. With modern lighting, air conditioning, and 24/7 work schedules, the initial reasons behind DST no longer hold the same weight.
An Extra Hour of Sleep—or an Adjustment Struggle?
While many people look forward to that “bonus” hour of sleep in November, health experts warn that even a one-hour shift can disrupt the body’s circadian rhythm—the natural internal clock that regulates sleep and wake cycles.
According to studies by the American Sleep Research Institute, the days following the time change often see increases in fatigue, workplace errors, heart issues, and traffic accidents.
Parents of young children, shift workers, and the elderly often find this transition particularly difficult. Some experts argue that keeping one consistent time year-round would benefit everyone’s well-being.
The Ongoing Time Debate
The topic of Daylight Saving Time continues to spark controversy. In April 2025, former President Donald Trump reignited the conversation, stating that DST should be made permanent because switching clocks twice a year is “inconvenient and costly.”
Interestingly, just months earlier in December 2024, he had suggested abolishing DST altogether and sticking to Standard Time permanently.
This back-and-forth reflects the broader national divide: some Americans love the extended daylight hours, while others prioritize brighter mornings—especially for schoolchildren and early commuters.
Why Is the Time Reform Bill Delayed?
The Sunshine Protection Act, passed by the U.S. Senate in 2022, aimed to make DST permanent nationwide. However, it stalled in the House of Representatives, preventing it from becoming law.
Although the bill was reintroduced in 2025, progress has been slow, and Congress has yet to reach an agreement on whether to adopt permanent DST or revert permanently to Standard Time.
States Taking Initiative
Some states aren’t waiting for federal action. In March 2025, Pennsylvania urged Congress to abolish the outdated practice altogether. To date, 29 states have introduced similar resolutions or bills.
Still, federal approval is mandatory for any state-level change, so individual states cannot independently choose to stay on permanent DST or Standard Time.
Which States Skip DST?
While most U.S. states observe Daylight Saving Time, a few do not participate.
| States/Territories | DST Observance |
|---|---|
| Hawaii | No |
| Arizona (except Navajo Nation) | No |
| Puerto Rico | No |
| Guam | No |
| American Samoa | No |
| Northern Mariana Islands | No |
| U.S. Virgin Islands | No |
These regions remain on Standard Time all year long.
What Happens on November 2, 2025?
At 2 a.m. on Sunday, November 2, 2025, clocks in states observing DST will be set back to 1 a.m. This marks the official end of Daylight Saving Time.
The adjustment means brighter mornings but darker evenings, signaling the arrival of shorter winter days. As temperatures drop, the sun will set earlier, often before many people finish their workday.
Is Daylight Saving Still Useful Today?
The original logic behind DST—saving energy—no longer appears valid. Recent U.S. studies reveal that DST now saves less than 1% of total electricity consumption.
Moreover, the biannual time shifts can cause sleep deprivation, reduced productivity, and mood disturbances. Many experts now argue that the drawbacks far outweigh the benefits in our modern, energy-efficient world.
Will the Practice Ever End?
For now, the future of Daylight Saving Time remains uncertain. Despite bipartisan support for change, Congressional gridlock and conflicting opinions continue to delay reform.
Until a new law is enacted, Americans will keep adjusting their clocks twice a year—once in March and again in November.
Conclusion
As Daylight Saving Time 2025 approaches, Americans prepare once again for that annual ritual. You’ll enjoy an extra hour of sleep, but also the revival of an old question: Is this time change still necessary?
When you reset your clocks this November, consider whether it’s finally time for the U.S. to reset its century-old timekeeping tradition.
