Daylight saving time ends early next month. According to the National Institute of Standards and Technology (NIST), DST is in effect in 2026 until Sunday, Nov. 1, at 2 a.m. local time, when clocks go back to 1 a.m. and that hour repeats. In other words, you get an extra hour of sleep.
Not everyone changes clocks. NIST notes that Hawaii, most of Arizona (the Navajo Nation is the exception), Puerto Rico, Guam, American Samoa and the U.S. Virgin Islands don’t observe daylight saving time.
1. Let your devices do the work
Phones, computers and most smart devices adjust automatically, as long as automatic time is turned on. On an iPhone or iPad, Apple says to go to Settings > General > Date & Time and turn on Set Automatically. For the time zone to follow your location, also check Settings > Privacy & Security > Location Services > System Services > Setting Time Zone.
On a Mac, Apple recommends turning on the options to set the time and date automatically and to set the time zone automatically in Date & Time settings, with Location Services enabled.
It’s worth a quick check now rather than discovering on Monday morning that an alarm went off an hour early.
2. Make a list of what won’t change itself
- Oven and microwave clocks
- Car dashboards
- Wall clocks and analog watches
- Older thermostats, sprinkler timers and coffee makers with schedules
- Some security cameras and doorbells, which can stamp footage with the wrong time
3. Test your smoke alarms
Changing the clocks is a handy reminder for home safety jobs. The U.S. Fire Administration recommends:
- Testing every smoke alarm monthly.
- Replacing batteries at least once a year in alarms that use 9-volt batteries, and replacing the backup battery in hardwired alarms at least once a year.
- Following the manufacturer’s instructions for sealed 10-year lithium alarms.
- Replacing the whole alarm every 10 years, counted from the manufacture date printed on it.
The agency also advises putting alarms inside and outside each sleeping area and on every level of the home, and choosing interconnected alarms so that when one sounds, they all do.
4. Plan for darker evenings
With sunset arriving an hour earlier on the clock, evening walks and commutes will be darker. It’s a good week to check porch lights, swap burned-out bulbs and make sure reflective gear and flashlights are easy to find.
