As we get closer to daylight saving time 2025, we’re here to share important dates, facts, and tips. Daylight saving time starts on Sunday, March 9, and ends on November 21. We’ll talk about how it works, its benefits, and what you can expect from this article.

Daylight saving time in the U.S. will begin on March 9, 2025, and end on November 2, 20252. We’ll look into its history, its effect on our daily lives, and offer tips for adjusting to the time change. Daylight saving time starts on the second Sunday in March and ends on the first Sunday in November3.
Key Dates for Daylight Saving Time 2025
As we get closer to dst 2025, remember to mark your calendar. The spring forward and fall back dates are important. Dst 2025 starts on March 9 and ends on November 24.
This rule applies to most states in the U.S. But Arizona and Hawaii don’t follow daylight saving time.
The idea of spring forward and fall back might seem tricky. But it’s key to know how these changes affect us. When we spring forward, we lose an hour of sleep. And when we fall back, we gain an hour.
This one-hour change can mess with our sleep, work, and health.
Here are the main dates for dst 2025:
- March 9: Spring forward – clocks move forward one hour
- November 2: Fall back – clocks move back one hour
Understanding the One-Hour Shift
As we get closer to the time change 2025, it’s key to grasp why we shift our clocks by an hour. This change has a rich history tied to World War I, when Germany first introduced it in 1916. The U.S. followed suit in 1918. Now, many European countries, like France, Italy, and the U.K., also observe daylight saving time.
Studies show that the time change affects our health and daily routines. For instance, a 2020 study revealed that daylight saving time increases fatal traffic accidents by 6%. It also disrupts sleep, causing people to lose about 40 minutes of sleep on the Monday after the change in March. Some effects include:
- Increased risk of heart attacks and strokes.
- Higher risk of mood disturbances and hospital admissions.
- Loss of sleep and cumulative sleep debt.

As we prepare for the time change 2025, understanding the impact is vital. We must adjust to the new schedule. Being aware of these effects helps us take steps to ease the transition.
The History Behind Daylight Saving Time
As we near the daylight saving time history in the United States, it’s key to grasp its origins. Germany was the first to adopt DST in 1915 during World War I. The U.S. followed on March 31, 1918, also during World War I. DST lasted about 7 months in the U.S. before being dropped in 1920.
The modern DST rules started with the Energy Policy Act of 2005, effective in 2007. This law aimed to save energy by making DST longer. In 2025, DST starts on March 9 at 2:00 A.M. and ends on November 2 at 2:00 A.M. About 70% of U.S. states and territories follow Daylight Saving Time.
Here’s a quick look at the dst 2025 schedule:
- Starts on the second Sunday in March
- Ends on the first Sunday in November
- Clocks are turned forward 1 hour in the spring
- Clocks are turned back 1 hour in the fall
The story of DST is filled with changes and shifts over time. Knowing the daylight saving time history and its effects on us is vital as we look ahead to the dst 2025 schedule.

Health and Safety Impacts of Time Changes
When we spring forward or fall back, our bodies adjust to the new sleep schedule. This can have big health effects. The time change can mess up our sleep patterns, leading to sleep deprivation and other problems.
About one-third of Americans don’t like the twice-yearly time changes. And 63% of Americans want to get rid of daylight saving time altogether.
Studies show that the time change in March can lead to more strokes and heart attacks. The start of Daylight Savings Time (DST) is on March 9th, 2025. Research says fatal car crashes go up by about 6% the week after DST starts.
Sleep loss affects more than just driving. It also impacts workplace safety, mainly in risky jobs like construction and healthcare.
Some important stats on the health and safety impacts of time changes include:
- Average of 3.6 more injuries occur on the Mondays following DST compared to other days.
- 24% increase in heart attack rates on the Monday after the DST change.
- Teenagers are hit hard by sleep loss due to the time change. The shift in melatonin release during puberty delays their natural sleep signals.

It’s crucial to know these health effects and take steps to lessen them, during the spring forward and fall back periods13. By understanding the risks, we can prepare better and reduce the negative impacts on our health and safety.
Preparing Your Home for DST Changes
