Every year, millions of Americans adjust their clocks for Daylight Saving Time (DST), but for many, the reason behind this shift remains unclear. In 2025, the end of DST will occur on Sunday, November 2, at 2:00 a.m., when clocks “fall back” by one hour. While some celebrate the extra hour of sleep, others question the ongoing impact of this age-old tradition. In this article, we’ll dive into the timing, implications, and debates surrounding DST, exploring its environmental, health, and social consequences, and also consider which states choose not to participate in this time change.

What Is Daylight Saving Time (DST)?
Daylight Saving Time (DST) involves adjusting clocks forward by one hour in the spring (“springing forward”) and moving them back one hour in the fall (“falling back”). This adjustment was initially designed to save energy by reducing the need for artificial lighting during the longer summer evenings.
How Does DST Work?
- Spring Forward: On the second Sunday in March, clocks are moved forward one hour at 2:00 a.m.
- Fall Back: On the first Sunday of November, clocks are moved back one hour at 2:00 a.m., returning to Standard Time.
In 2025, DST starts on March 9 and ends on November 2.
When Does Daylight Saving Time End in 2025?
End of Daylight Saving Time 2025
- Date: Sunday, November 2, 2025
- Time: At 2:00 a.m., clocks will fall back one hour, returning to 1:00 a.m..
This marks the conclusion of the 2025 daylight saving period, and people will enjoy an extra hour of sleep or more time for late-night activities.
Next DST Start
- The next DST will begin on March 8, 2026.
Which States Do Not Observe Daylight Saving Time?
Although most of the U.S. follows DST, some regions do not participate:
- Hawaii
- Most of Arizona (excluding the Navajo Nation)
- U.S. Territories (Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, Northern Mariana Islands)
These regions stay on Standard Time year-round, avoiding the shift altogether.
Key States and Their DST Policies
| State | DST Observance |
|---|---|
| Hawaii | Does not observe DST |
| Arizona | Does not observe DST (except Navajo Nation) |
| California | Observes DST |
| New York | Observes DST |
| Texas | Observes DST |
About 95% of Americans follow the time change, while 5% in these regions remain on Standard Time.
Why Does Daylight Saving Time Matter?
Energy Savings
The original idea behind DST was to reduce energy consumption by extending daylight hours, thus minimizing the need for artificial lighting and heating. However, modern technology and lifestyle shifts have reduced the effectiveness of this concept, with some arguing that it has a negligible impact on overall energy savings today.
Health and Safety Concerns
Health experts have raised concerns about the health impacts of shifting clocks. Circadian rhythm disruption is linked to an increase in heart attacks, strokes, and accidents right after the time changes. Fatigue and disorientation are common in the days following the switch, potentially affecting productivity and well-being.
Economic Impact
Although Daylight Saving Time is designed to benefit the economy by encouraging evening activity, its actual impact on business productivity and market trends is still debated. Wall Street, for example, has noted that the time change can disrupt productivity.
Life After the Time Change
After DST ends:
- Mornings become brighter, making it easier to start the day.
- Evenings get darker sooner, affecting outdoor activities and early evening routines.
- Sunset in New York City will occur around 4:50 p.m. by mid-November.
- As we approach the winter solstice on December 21, expect only 9 hours and 17 minutes of daylight — the shortest day of the year.
These changes can alter people’s routines, driving patterns, and even social habits, as fewer daylight hours mean more indoor time.
Should Daylight Saving Time Be Stopped?
Many Americans have expressed frustration over the annual clock changes. According to a Pew Research poll, 63% of Americans want to end the practice of switching clocks. Proponents argue that permanent standard time would reduce confusion, improve sleep quality, and decrease health risks associated with the shift.
In response to growing demand for change, some states and lawmakers are pushing for permanent Daylight Saving Time to be implemented year-round. The Sunshine Protection Act, first introduced in 2018, aims to make DST permanent. However, this legislation is still under debate in Congress and has not yet passed.
FAQs
1. When does Daylight Saving Time end in 2025?
Daylight Saving Time ends on Sunday, November 2, 2025, at 2:00 a.m., when clocks will fall back one hour.
2. What happens when the clocks “fall back”?
When the clocks fall back, you gain an hour — either for extra sleep or late-night activities.
3. Why do some states not observe DST?
States like Hawaii and Arizona have opted out of the practice due to geographic and cultural reasons. They prefer to stay on Standard Time year-round.
4. Is Daylight Saving Time really effective in saving energy?
While Daylight Saving Time was originally intended to save energy, its effectiveness is debated, especially in modern society with greater reliance on electricity for cooling and heating.
5. Can Daylight Saving Time be permanently ended?
There are ongoing debates and legislative efforts like the Sunshine Protection Act, which would end the twice-yearly clock changes, but Congress has not yet passed a law to make DST permanent.
