When do the clocks change?

November 1, 2026
clocks go back

39 days from today. At 2:00 am local time the clocks go back to 1:00 am, so the day is 25 hours long. Dates are the same across the US.

What actually happens

US daylight saving runs from the second Sunday in March to the first Sunday in November, fixed by the Energy Policy Act of 2005. Clocks move at 2am local time in each zone, not simultaneously across the country — so the change sweeps west, reaching Hawaii three hours after New York, except that Hawaii does not take part.

In March 2am becomes 3am and the hour between never exists; a timer set for 2:30am that morning has no moment to fire. In November 1:59am is followed by 1:00am and the hour happens twice, which is why timestamps that day need an offset and not just a clock reading.

Every date to 2031

Every year has the same shape — both changes fall on a Sunday at 2am local time, and daylight saving runs 238 days — so there is no separate page per year to say it again. Only the dates move, and they are all above.

The states that sit it out

Arizona and Hawaii do not observe daylight saving, which is why “what time is it in Arizona” is the most-searched question in this whole cluster — Arizona matches Pacific Time in summer and Mountain Time in winter, so the answer depends on the month in a way it does not anywhere else.

Current time in Arizona. Current time in Hawaii. The Navajo Nation, inside Arizona, does observe it — and the Hopi Reservation, inside the Navajo Nation, does not.

Most of the world does not do this

Of the 246 countries with a time zone of their own, 180 never change their clocks — 73% of them. Daylight saving is largely a European and North American habit, and the countries that keep it do not all change on the same day.

Europe moves a week before North America, so for those days the gap between London and New York is four hours rather than the usual five. The converter lists that window for any pair.
