Daylight savings time begins Sunday at 2 a.m. in most places in the United States.
Residents are reminded to set their clocks ahead one hour before they go to bed on Saturday night. Most cell phones, computers and other electronic devices automatically make the time switch at 2 a.m.
Since 2007, daylight savings time has run from the second Sunday in March until the first Sunday in November, when clocks are set back an hour to return to Standard Time.
The time change allows for later daylight hours during the summer months. Arizona and Hawaii are the only states in the United States that do not recognize daylight savings time.
