Daylight saving time in the United States is the practice of setting the clock forward by one hour during the warmer part of the year, so that evenings have more daylight and mornings have less. Most areas of the
United States currently observe
daylight saving time (DST), the exceptions being
Arizona (except for the
Navajo Nation, which does observe daylight saving time),[SUP]

Hawaii,[SUP]

overseas territories of
Puerto Rico,
American Samoa,
Guam, the
Northern Mariana Islands, and the
United States Virgin Islands.Daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, with the time changes taking place at 2:00 a.m. local time. With a
mnemonic word play referring to seasons, clocks "spring forward and fall back"—that is, in spring (technically late winter) the clocks are moved forward from 2:00 a.m. to 3:00 a.m., and in fall they are moved back from 2:00 am to 1:00 am.
The following table lists recent past and near future starting and ending dates of daylight saving time in the United States:
