Overview
- The switch occurs at 2:00 a.m. local time on Sunday, November 2, when clocks move back to 1:00 a.m.
- Returning to standard time brings earlier sunrises and earlier sunsets, with dusk near 6 p.m. Eastern, and provides an extra hour of sleep.
- Most smartphones, computers and smartwatches will update automatically if the automatic time setting is enabled.
- Federal law sets the current schedule, with DST running from the second Sunday in March to the first Sunday in November under a 2005 change.
- Jurisdictions that do not observe DST include Hawaii, most of Arizona, Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands and American Samoa.
