Daylight Saving Time (DST) in the United States will end annually on November 2, 2025. On this day, clocks are set back one hour, returning the country to Standard Time, which will remain in effect until March 2026.
This tradition began in the 20th century, primarily aimed at maximizing natural light and reducing electricity consumption during the summer months.
But in recent years, there has been increasing debate about DST. Many experts believe that this time change can affect people’s sleep patterns, mental health, and work efficiency. For this reason, some states have decided to end the time change, while others are still in the process.

Which states will not observe Daylight Saving Time in 2025?
To date, only two US states have completely abandoned DST and observe the same time all year:
1. Hawaii
Hawaii observes Standard Time year-round. Because this location is close to the equator, there is very little variation in sunlight throughout the year, so DST is not necessary.
2. Arizona (Except for Some Parts)
Arizona also keeps the same time year-round.
However, the Navajo Nation observes DST because some of its territory is adjacent to neighboring states that change time.
In addition, DST is not enforced in some U.S. territories:
- Puerto Rico
- Guam
- U.S. Virgin Islands
- American Samoa
- Northern Mariana Islands
These territories also observe standard time year-round. In these places, the weather and daylight vary little, so changing the time is not considered practical.
Which states are moving towards eliminating DST?
While only two states have completely abolished DST, at least 10 other US states have passed laws allowing them to permanently implement DST in the future—meaning the clocks won’t change year-round.
These states include:
- Florida
- Alabama
- Georgia
- Louisiana
- Tennessee
- Maine
- Texas
- Wyoming
- Delaware
- Oregon
These states aim to either remain on Daylight Saving Time forever or maintain the same time without any change. However, US law (federal law) only allows states to opt out of DST and remain on standard time.
Conversely, states are not allowed to implement DST year-round unless Congress approves it.
Why is the situation in some states still stuck?
Some states, such as
- Wyoming
- Delaware
- California
have passed resolutions or referendums but are still awaiting decisions from neighboring states or federal government approval.
This coordination is necessary because a different time in one state and a different time in a neighboring state can cause confusion and time-related problems.
How will the time change happen in 2025?
In 2025, DST began on March 9th and will end on November 2nd. During this time period, 48 states will still observe the time change.
The good news is that today:
- Smartphones
- Computers
- Smartwatches
automatically update the time, so people don’t need to manually adjust their clocks.
Will DST continue or end? The future of DST
National debate on the issue of DST has increased in recent years. Some believe the time change impacts health and sleep, while others still cite the benefits of energy savings and longer days.
The key point is that Congressional approval is required to completely eliminate DST or implement it year-round. Until that happens, the entire United States will not be able to adopt a uniform policy.
Conclusion
By 2025, only Hawaii and Arizona will be the only states that will not implement Daylight Saving Time.
Although several states have passed laws against it, they are still awaiting federal approval.
More changes to DST may be expected in the future, as people are gradually questioning the necessity of this practice.
