Fall Back 2025

Clocks fall back on Sunday, November 2, 2025 at 2:00 AM. At this moment, clocks automatically move back to 1:00 AM, giving everyone an extra hour. This marks the end of daylight saving time and the return to standard time until March 2026.

The phrase "fall back" helps people remember which direction clocks move in autumn. Unlike spring when we lose an hour, November's time change gives you one additional hour to sleep, work, or enjoy your Sunday.

Understanding the Clock Change

The United States has changed clocks twice yearly since 1966, when the Uniform Time Act standardized the practice. The current schedule - spring forward on the second Sunday in March, fall back on the first Sunday in November - has been in effect since 2007.

What Actually Happens

At precisely 2:00 AM on November 2nd, clocks automatically jump back to 1:00 AM. This means the hour from 1:00 to 2:00 AM technically occurs twice. Most digital devices connected to the internet adjust automatically, but many clocks still require manual changes.

States That Don't Participate

Hawaii and most of Arizona maintain the same time year-round. The Navajo Nation in Arizona observes daylight saving time, creating a patchwork of time zones within the state. US territories including Puerto Rico, Guam, American Samoa, and the US Virgin Islands also don't change clocks.

Which Clocks Need Changing

Modern technology has simplified the twice-yearly ritual of changing clocks, but some devices still require manual adjustment.

Automatic Updates

Smartphones, tablets, computers, smart TVs, and most internet-connected devices adjust automatically. Modern cars with GPS-based clocks also update themselves. These devices pull time from network servers that synchronize with atomic clocks.

Manual Changes Required

Traditional wall clocks, wristwatches, microwave and oven displays, car clocks (in older vehicles), alarm clocks, and some thermostat timers need manual adjustment. Create a checklist Saturday evening to ensure you catch everything.

Pro tip: Change clocks before bed Saturday night rather than Sunday morning. This prevents confusion and ensures you're on the correct schedule when you wake up.

Adjusting Your Sleep Schedule

Though falling back is easier on the body than springing forward, it can still disrupt sleep patterns and circadian rhythms. Strategic preparation minimizes the impact.

Gradual Transition Method

Starting Wednesday before the time change, shift your bedtime 15-20 minutes later each night. By Saturday, you'll be going to bed nearly an hour later, aligning your natural schedule with the coming time change. This gradual approach prevents the jarring effect of an abrupt shift.

Light Exposure Strategy

Light is the most powerful tool for adjusting your internal clock. On Sunday morning after the change, get bright light exposure early - go outside, open curtains wide, or use a light therapy lamp. This signals your brain that it's time to be awake on the new schedule.

Conversely, dim lights in the evening and avoid screens an hour before bed. This helps maintain your sleep pressure and prevents the extra evening hour from disrupting your sleep onset.

Children and Time Changes

Young children often struggle more with time changes than adults. Start adjusting bedtime and wake time by 10-15 minutes several days before. Maintain consistent nap schedules using the new time immediately on Sunday. Darken rooms completely for sleep to prevent early waking from increased morning sunlight.

Health Effects of Time Changes

Research reveals that even a one-hour shift impacts health, productivity, and safety in measurable ways.

Sleep Disruption

Studies show people sleep about 40 minutes less than usual on the night of a time change, regardless of direction. This sleep debt can persist for up to a week as circadian rhythms gradually adjust. The disruption affects cognitive performance, mood, and reaction times.

Accident Rates

The Monday following a time change sees increased workplace accidents and traffic collisions. The spike is particularly pronounced after spring forward, but fall back also shows elevated risk as people adjust to darker evening commutes.

Cardiovascular Impact

Some research suggests a small but measurable increase in heart attacks in the days following time changes. The mechanism isn't fully understood but may relate to stress on the cardiovascular system from disrupted sleep patterns.

The Ongoing Debate

Daylight saving time remains controversial, with passionate advocates on both sides and growing momentum for permanent standard time or permanent daylight time.

Arguments for Permanent Daylight Time

Proponents cite longer evening daylight for recreation, reduced crime (more activity during daylight hours), and economic benefits for businesses. The Sunshine Protection Act, which would make daylight time permanent, has garnered significant support in Congress.

Arguments for Permanent Standard Time

Sleep scientists overwhelmingly support permanent standard time, arguing it aligns better with human circadian biology. Standard time provides more morning light, which is crucial for wakefulness and mood regulation. The American Academy of Sleep Medicine officially recommends abolishing daylight saving in favor of year-round standard time.

Current Legislative Status

Multiple states have passed legislation to adopt permanent daylight time, but these laws can't take effect without federal approval. Congress would need to amend the Uniform Time Act to allow states this flexibility. As of 2025, the debate continues without resolution.

Making the Most of Your Extra Hour

While the time change brings disruption, it also offers a genuine gift: an additional hour on Sunday, November 2nd. How you use this bonus time can set the tone for the week ahead.

Consider dedicating the extra hour to something meaningful rather than just sleeping in. Take a longer morning walk, prepare a special breakfast, tackle a project you've been postponing, or simply enjoy quiet reflection time. Framing the time change as an opportunity rather than an annoyance can shift your perspective.

For families, the extra hour provides time for activities often rushed on typical Sunday mornings - pancake breakfast together, board games, or a nature walk. These moments create positive associations with the time change rather than focusing on the disruption it brings.
