Daylight Saving Time returns this weekend. On Sunday, most Americans will lose one hour of sleep but gain an hour of evening light when clocks "spring forward" an hour.
The change officially occurs at 2 a.m. (local time) on that date. For many people, the change no longer requires actually moving the hands on a clock - many electronic devices such as cell phones and "smart devices" automatically make the change.
Some people enjoy the twice-yearly ritual of tinkering with time, feeling that “springing forward” or “falling back” helps to usher in a more seasonal atmosphere. Other people, however, don’t like the idea of trying to trick our bodies and our daily routines by adjusting the clocks.
According to the Department of Transportation, the purpose of daylight saving time is that it saves energy, saves lives and prevents traffic injuries, and reduces crime.
Several states and territories in the U.S. do not observe it, including the Virgin Islands, American Samoa, Puerto Rico, Guam, Arizona, and Hawaii.
According to Time and Date, daylight saving time originated in Germany on April 30, 1916. In 1942, President Franklin D. Roosevelt enacted year-round Daylight Saving Time in the United States.
Clocks will "fall back" to Standard Time when Daylight Saving Time ends on November 6 at 2 a.m.
