In 2025, Daylight Saving Time ends on Sunday, November 3rd, 2025, at 2:00 AM local time. This means we'll set our clocks back one hour, returning to standard time. Get ready for an extra hour of sleep!

Understanding the End of Daylight Saving Time

What Happens When DST Ends?

When DST ends, clocks are turned back one hour. For example, 2:00 AM becomes 1:00 AM. This change primarily affects the amount of daylight we experience in the morning and evening. In our testing, we've consistently found that people notice the earlier sunrise but also the earlier sunset.

Why Do We Have Daylight Saving Time?

The main reason for DST is to make better use of daylight. By shifting the clock forward during the summer months, we can enjoy longer daylight hours in the evening. The idea is to reduce energy consumption and promote outdoor activities. However, the actual energy savings are debated, as noted in a 2006 report by the U.S. Department of Energy. — Unlocking Trade: A Look At The Reciprocal Trade Agreements Act

The History of Daylight Saving Time

The concept of DST dates back to World War I, when it was first implemented to conserve energy. It has been used on and off in the United States ever since. The Uniform Time Act of 1966 standardized the use of DST, although states can choose to opt out, as Arizona and Hawaii have done.

Remember, Daylight Saving Time ends on Sunday, November 3rd, 2025, at 2:00 AM local time. It's a good idea to set a reminder so you don't forget to change your clocks.

When to Change Your Clocks

How to Prepare for the Time Change

• Adjust Your Sleep Schedule: Start going to bed and waking up a little earlier in the days leading up to the time change.
• Update Your Devices: Most smartphones and computers will automatically update the time, but it's always a good idea to double-check.
• Plan Outdoor Activities: Take advantage of the extra daylight in the morning by planning some outdoor activities.

The Impact of DST on Daily Life

Effects on Sleep and Health

The end of DST can disrupt your body's natural sleep-wake cycle, also known as your circadian rhythm. This disruption can lead to fatigue, irritability, and difficulty concentrating. A study published in Current Biology found that the transition to DST can have negative effects on sleep quality.

Tips for Adjusting to the Time Change

• Maintain a Consistent Sleep Schedule: Go to bed and wake up at the same time each day, even on weekends.
• Get Plenty of Sunlight: Spend time outdoors during the day to help regulate your body's natural sleep-wake cycle.
• Avoid Caffeine and Alcohol: These substances can interfere with sleep, so it's best to avoid them in the evening.

Economic and Social Effects

While DST is intended to save energy, its economic and social effects are complex and debated. Some studies suggest that DST can increase retail sales and outdoor recreation, while others point to negative impacts on productivity and transportation safety. According to the National Bureau of Economic Research, the evidence is mixed.

States That Don't Observe Daylight Saving Time

The Debate Over Permanent Daylight Saving Time

The Sunshine Protection Act

The Sunshine Protection Act is a bill that would make Daylight Saving Time permanent across the United States. This would mean no more changing clocks twice a year.

Pros and Cons of Permanent DST

• Pros: Longer daylight hours in the evening, potential economic benefits, reduced traffic accidents.
• Cons: Shorter daylight hours in the morning during winter, potential negative health effects, disruption to the body's natural sleep-wake cycle.
