Twice a year, clocks move by an hour across much of the world. Most travelers notice it once, the morning their phone quietly updates. But the change doesn't happen everywhere on the same day, and that gap catches people out.

The Week That Doesn't Line Up

In 2026, Europe ends daylight saving time on Sunday, October 25. The United States follows a week later, on Sunday, November 1. For those seven days, New York is four hours behind London instead of the usual five. The same one-hour shift applies between every European and North American city that observes daylight saving time.

Not everywhere changes at all. Arizona (outside the Navajo Nation) and Hawaii stay on standard time all year, as do most of Asia and Africa. In the Southern Hemisphere, places such as much of Australia move their clocks forward in spring, which is October.

What It Means for Your Trip

  1. Flight times are always local. A departure at 9:00 and an arrival at 11:30 are each in their own city's time. The flight doesn't get longer or shorter, but the gap between the two printed times changes.
  2. Schedules can shift. Airlines sometimes adjust departure times around the change to keep slots or connections working. Check your booking in the week before you fly.
  3. Plans on the ground can slip. A video call, a hotel check-in or a train booked in another time zone can be an hour off if you worked out the difference before the change.

How to Avoid Getting Caught

  1. Check the date of the change at both ends of your trip, not just at home.
  2. Recheck your itinerary a few days before departure, especially for flights in late October and early November, or in March, when the same thing happens in reverse.
  3. Write times in the local zone of each event, and let your phone or calendar convert them, rather than doing the math yourself.
  4. Give tight connections a little extra room if a schedule change has shortened them.
