Don’t forget to turn your clock back one hour on Sunday, November 2. The transition officially happens at 2:00 a.m. local daylight time, which becomes 1:00 a.m. local standard time.

The majority of the United States observes daylight time, but there are some exceptions, including Hawaii and most of Arizona. Many other countries observe some change in time, but not necessarily on the same dates as the U.S.
