When Do We Fall Back in 2017
In the United States and most of North America in 2017, Daylight Saving Time ends on Sunday, November 5, 2017, when clocks fall back at 2:00 AM local time to 1:00 AM. This annual shift marks the return to Standard Time and adds an extra hour of sleep that weekend. The transition affects scheduling, sunrise and sunset times, and energy practices. Below is a concise table of key details, followed by background, regional exceptions, and practical guidance to help you prepare for the change.

Background on Daylight Saving Time
Daylight Saving Time is the practice of advancing clocks during warmer months to extend evening daylight, then returning clocks to Standard Time in autumn. In the U.S., the Energy Policy Act of 2005 set a national schedule: clocks move forward on the second Sunday in March and fall back on the first Sunday in November. This rule produces a November transition that minimizes disruption while maximizing evening light during the longer days of summer.
Why the November Fall Back Matters
The November shift changes when the sun rises and sets relative to the clock, affecting school commutes, work schedules, and outdoor activities. The later sunrise can make morning travel darker, while the earlier sunset shifts peak activity to daylight hours. Understanding this change helps individuals plan commutes, exercise, and routines for the roughly five months of Standard Time that follow.
Regional Exceptions and Special Cases
Not all regions observe this fall-back change. Most of Arizona and Hawaii do not observe Daylight Saving Time and remain on Standard Time year-round. U.S. territories—including Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands—also do not change clocks. Within states that do observe DST, local ordinances may apply; for example, the Navajo Nation observes DST, while the Hopi Reservation does not. Indiana historically had complex arrangements, but by 2017 most of the state follows the federal schedule.
Practical Impact and Preparation
On the night of November 4, set clocks back one hour before bed or use devices that update automatically. Prepare for earlier sunsets by checking updated sunrise and sunset times for your location. Adjust morning alarms if preferred sunrise brightness is part of your routine. Verify that critical systems—security alarms, calendar events, and timestamps—are set to the correct Standard Time offset. These steps reduce scheduling errors and make the transition seamless.
Misconceptions and Common Questions
A common question is whether the November change affects the start of the new year or daylight patterns beyond the local week; it does not. The change is purely a clock adjustment within the same day. It’s also sometimes confused with the March forward transition, which reduces sleep by an hour and can disrupt sleep patterns more noticeably. In 2017, the March change occurred on March 12, and the November change occurred on November 5. No other time shifts occur that year in regions observing DST.
Global Context and Comparison
Not all countries change clocks on the same dates. Many observe their own DST schedule based on latitude, daylight duration, and energy policy. In the Northern Hemisphere’s autumn, numerous nations move clocks back around late September to early November, while others make no change. Travelers and remote collaborators should confirm local rules to avoid confusion. Standard Time in November typically aligns sunrise and sunset closer to clock noon at higher latitudes, a practical consideration for daily planning.
Evergreen Takeaways
- In 2017, the U.S. falls back on Sunday, November 5, at 2:00 AM local time.
- Clocks move back one hour, shifting from EDT (UTC-4) to EST (UTC-5).
- Most of the U.S. and Canada observe the change; Arizona, Hawaii, and U.S. territories do not.
- Plan for earlier sunsets and adjust morning routines and devices accordingly.
- Automatic updates help devices stay accurate; verify critical clocks and schedules manually.
Conclusion
To answer the direct question—when do we fall back in 2017?—the transition happens on Sunday, November 5, at 2:00 AM local time across most of the United States and Canada. Treat this as an evergreen reference: as long as regions maintain the same DST rules, the pattern repeats predictably each year. Use this date to align schedules, automate devices, and adapt routines for Standard Time, ensuring continuity and accuracy throughout the season.
