Daylight Savings Time 2025 (DST) is an annual event affecting millions across various regions. In 2025, the time change will once again bring an adjustment to our schedules. Whether you’re looking to prepare for the change or simply curious about its impact, this guide covers everything you need to know about Daylight Savings Time 2025.
When Does Daylight Savings Time Start in 2025?
In the United States, Daylight Savings Time 2025 begins on Sunday, March 9, 2025, at 2:00 AM local time. At this moment, clocks will “spring forward” one hour, meaning that 2:00 AM will instantly become 3:00 AM. While this shift results in losing an hour of sleep, it also brings longer daylight hours in the evening.
When Does Daylight Savings Time End in 2025?
DST in the U.S. will end on Sunday, November 2, 2025, at 2:00 AM local time. Clocks will “fall back” one hour, meaning 2:00 AM will revert to 1:00 AM. This change allows for an extra hour of sleep and marks the return to Standard Time.
Why Do We Observe Daylight Savings Time?
The primary reason for Daylight Savings Time is to make better use of natural daylight. By shifting the clock forward in the spring, people enjoy more daylight in the evening, which can lead to energy savings and increased productivity. Some of the key benefits include:
- Energy Conservation – Longer daylight hours reduce the need for artificial lighting.
- Economic Benefits – Businesses, especially those in retail and tourism, benefit from extended daylight.
- Health and Well-Being – More daylight hours encourage outdoor activities, improving overall well-being.
Which States and Countries Observe DST?
In the United States, most states follow Daylight Savings Time except for Hawaii and most of Arizona, which remain on Standard Time year-round. Many other countries, including Canada, the UK, and parts of Europe, also observe DST, but their start and end dates may differ.
How to Prepare for the Daylight Savings Time Change
Adjusting to Daylight Savings Time 2025 can take time, but there are steps you can take to ease the transition:
- Gradually Adjust Sleep Schedules – Shift bedtime by 15–30 minutes a few days before the change.
- Limit Screen Time Before Bed – Blue light from screens can disrupt sleep patterns.
- Get Morning Sunlight – Natural light exposure helps regulate the body’s internal clock.
- Check Clocks and Devices – Ensure your clocks update automatically or manually adjust them.
The Ongoing Debate on Daylight Savings Time
While DST offers advantages, there has been ongoing debate about its effectiveness. Some argue that the disruption to sleep patterns and minimal energy savings do not justify the time change. As a result, some states and countries have proposed eliminating DST permanently.
Daylight Saving Time in the United States
Daylight Saving Time (DST) is the practice of moving the clocks forward by one hour in the spring and back by one hour in the fall to make better use of daylight during the warmer months. In the United States, DST begins on the second Sunday in March and ends on the first Sunday in November each year.
History of Daylight Saving Time in the U.S.
- Introduced in 1918: The U.S. first adopted Daylight Saving Time during World War I to conserve energy.
- Repealed and Reinstated: After the war, DST was repealed but returned during World War II for similar energy-saving reasons.
- Standardization in 1966: The Uniform Time Act established a consistent DST schedule across the country.
- Extensions in 1986 and 2007: The start and end dates were adjusted, with the most recent change in 2007 setting the current March-November timeframe.
When Does Daylight Saving Time Occur?
- Starts: Second Sunday in March (Clocks “spring forward” one hour at 2:00 AM)
- Ends: First Sunday in November (Clocks “fall back” one hour at 2:00 AM)
Which States Do Not Observe DST?
- Hawaii and most of Arizona (excluding the Navajo Nation) do not follow Daylight Saving Time.
- U.S. territories like Puerto Rico, Guam, the U.S. Virgin Islands, and American Samoa also do not observe DST.
Pros and Cons of Daylight Saving Time
Pros:
- Extends daylight hours for evening activities
- Reduces energy consumption for lighting
- May benefit businesses and outdoor activities
Cons:
- Can disrupt sleep patterns and circadian rhythms
- Potentially increases the risk of heart attacks and accidents after the time change

Future of Daylight Saving Time in the U.S.
Ongoing debate has been about whether DST should be abolished or made permanent. The Sunshine Protection Act, which proposes keeping DST year-round, has been introduced multiple times in Congress, but no nationwide change has been made yet.
