Get ready for an extra hour of sleep! Daylight Saving Time (DST) ends in the United States on November 2, 2025. This means it’s time to set your clocks back and enjoy the slightly earlier sunsets.
While the change can be a welcome shift for those who appreciate more daylight in the morning, it also signals the arrival of shorter days and the transition into winter. Here’s what you need to know about the end of Daylight Saving Time in 2025.
When to Turn Back Your Clocks
The Official Date and Time
Daylight Saving Time officially ends at 2:00 AM local time on Sunday, November 2, 2025. At that moment, clocks will be turned back one hour to 1:00 AM. This change occurs automatically on most smartphones and other connected devices, but it’s a good idea to double-check and manually adjust any traditional clocks you may have.
The shift to standard time means that sunrise and sunset will each occur an hour earlier on November 2 than the day before. There will be more daylight in the morning and less in the evening.
Why 2:00 AM?
The reason DST switches at 2:00 a.m. is rooted in practicality. This time was chosen to minimize disruption to transportation and schedules. By making the change in the early morning hours, there’s less impact on travel and appointments.
Think about it: fewer trains are running and it affects the least amount of people traveling at that hour. It’s a compromise aimed at making the transition as smooth as possible for most sectors of society. Learn more about why 2 AM was chosen.
States That Don’t Observe DST
It’s important to remember that not all of the United States participates in Daylight Saving Time. Arizona (with the exception of the Navajo Nation) and Hawaii do not observe DST. This means that residents of these states will not need to change their clocks in November.
The decision to opt out of DST is often based on geographical location and the desire to maintain consistent daylight hours throughout the year. For example, Hawaii’s proximity to the equator means that the difference in daylight hours between summer and winter is minimal.
Preparing for the Time Change
Adjusting Your Sleep Schedule
Even though gaining an hour of sleep sounds appealing, the time change can still disrupt your body’s natural sleep-wake cycle. To minimize the impact, it’s recommended to gradually adjust your sleep schedule in the days leading up to November 2.
Try going to bed and waking up 15-20 minutes earlier each day. This will help your body adapt to the new time more easily. It’s also a good idea to maintain a consistent sleep schedule on weekends, even after the time change.
Other Preparations
In addition to adjusting your sleep schedule, there are a few other things you can do to prepare for the end of Daylight Saving Time. Update your clocks and timers, including those in your car and on appliances. This will ensure that you’re on the correct time and avoid any confusion.
Also, take some time to adjust your routines to account for the earlier sunsets. If you typically exercise outdoors in the evening, you may need to find an alternative time or location. Be mindful of increased darkness during your commute and take extra precautions when driving or walking.

The Debate Around Daylight Saving Time
Arguments for and Against DST
Daylight Saving Time has been a subject of debate for many years. Proponents argue that it saves energy, reduces traffic accidents, and promotes outdoor recreation. They believe that by shifting daylight hours, people are more likely to be active and spend time outdoors.
Opponents, on the other hand, argue that DST disrupts sleep patterns, leads to health problems, and has minimal impact on energy consumption. Studies have shown that the time change can negatively affect productivity, increase the risk of heart attacks, and disrupt the body’s natural circadian rhythm.
Calls for Permanent Standard Time
In recent years, there has been growing support for abolishing Daylight Saving Time and adopting permanent standard time. Advocates argue that this would eliminate the disruption caused by the time change and promote better health and well-being.
Several states have already passed legislation to make Daylight Saving Time permanent, but these laws cannot take effect until Congress approves a federal change. The Sunshine Protection Act, which would make DST permanent nationwide, has been introduced in Congress but has yet to be passed.
The Economic Impact
The economic impact of Daylight Saving Time is another area of debate. Some studies suggest that DST increases consumer spending, as people are more likely to shop and dine out when there is more daylight in the evening. However, other studies have found that DST has little or no impact on economic activity.
The complexity of the issue makes it difficult to draw definitive conclusions about the economic effects of DST. Factors such as geographic location, industry sector, and consumer behavior can all play a role.
The History of Daylight Saving Time
Origins and Early Adoption
The concept of Daylight Saving Time was first proposed by Benjamin Franklin in 1784 as a way to conserve energy. However, it wasn’t until World War I that DST was widely adopted as a wartime measure.
Germany and Austria-Hungary were the first countries to implement DST in 1916, followed by other European nations and the United States in 1918. The goal was to save fuel by extending daylight hours into the evening, reducing the need for artificial lighting.
Variations and Changes Over Time
Since its initial adoption, Daylight Saving Time has undergone numerous changes and variations. During World War II, the United States implemented year-round DST, known as “War Time,” to further conserve energy.
After the war, DST was repealed, but it was later reinstated in 1966 with the passage of the Uniform Time Act. This law established a standard system for DST in the United States, but it also allowed states to opt out of observing DST if they chose to do so.
The Energy Saving Myth
While one of the original reasons for implementing Daylight Saving Time was to save energy, studies have shown that the actual energy savings are minimal, and in some cases, DST may even increase energy consumption.
Modern life is more complex, and energy usage patterns have changed significantly since the early 20th century. Air conditioning, electronic devices, and other factors can offset any potential energy savings from DST.
Health and Safety Considerations
Impact on Sleep and Circadian Rhythm
The disruption to sleep patterns caused by Daylight Saving Time can have a significant impact on health and well-being. Studies have shown that the time change can lead to sleep deprivation, which can increase the risk of accidents, decrease productivity, and weaken the immune system.
The body’s natural circadian rhythm, which regulates sleep-wake cycles, can take several days or even weeks to adjust to the time change. This can result in fatigue, irritability, and difficulty concentrating.
Potential Health Risks
In addition to sleep disruption, Daylight Saving Time has been linked to other potential health risks. Some studies have found that the time change can increase the risk of heart attacks, strokes, and other cardiovascular events.
The exact mechanisms behind these risks are not fully understood, but it is believed that the sudden shift in sleep patterns and circadian rhythm can put stress on the body and increase inflammation.
Safety Concerns
Daylight Saving Time can also raise safety concerns, particularly during the transition period. The change in daylight hours can affect visibility for drivers and pedestrians, increasing the risk of traffic accidents.
It’s important to be extra cautious when driving or walking in the days following the time change. Be aware of your surroundings, use headlights when necessary, and watch out for pedestrians and cyclists.
