Daylight saving time ends Halloween weekend: When to set clocks back in 2026

Halloween falls on Saturday this year, and there’s one more thing to remember before calling it a night: Set your clocks back.

Daylight saving time ends at 2 a.m. Sunday, Nov. 1, 2026, in Oregon and Washington. Clocks move back one hour to 1 a.m., giving the Halloween weekend an extra hour before Sunday morning.

Whether you’re heading out for trick-or-treating, attending a costume party, or spending Halloween at home, add the time change to your weekend checklist.

Here’s what to know before the calendar turns to November.

When should you set your clocks back this Halloween weekend?

If you have clocks that need to be adjusted manually, turn them back one hour before going to bed on Saturday, Oct. 31.

The official change happens early Sunday morning, after Halloween night. At 2 a.m., the clock returns to 1 a.m., and that hour repeats.

Most phones and computers should update automatically when their automatic time settings are enabled. Check the clocks on your stove, microwave, vehicle dashboard, and other devices that may need a manual adjustment.

Will the time change affect trick-or-treating?

The clocks won’t change until after Halloween evening, so Saturday’s trick-or-treating plans take place before the switch.

The difference arrives Sunday, when sunset shifts an hour earlier on the clock. Moving back to standard time shifts daylight toward the morning; it doesn’t change the amount of daylight the day receives.

For Pacific Northwest residents and visitors planning a Sunday hike, scenic drive, or afternoon outing, that earlier sunset is worth keeping in mind.

Does everyone in the Pacific Northwest fall back?

Washington and Oregon will turn their clocks back this weekend. Washington and most of Oregon observe Pacific Time, while part of eastern Oregon observes Mountain Time. The change happens at 2 a.m. local time.

Travelers heading into British Columbia should pay attention to a different rule this year. Most of the province now observes permanent year-round Pacific Time and will not turn clocks back on Nov. 1. Existing local Mountain Time arrangements remain in place.

That means Vancouver and Victoria will be one hour ahead of Seattle and Portland after the U.S. time change. Double-check local times when making cross-border travel plans or scheduling calls.

What’s the reminder before Halloween night ends?

Before heading to bed Saturday, turn any manual clocks back one hour and check your Sunday plans.

Halloween is Saturday, Oct. 31. The time change follows early Sunday, Nov. 1.
