Don’t Forget to Change Your Clocks This Weekend
On Sunday, Daylight Saving Time officially ends at 2:00 a.m. local time. You’ll need to set your clock back one hour to adjust for the change.
Daylight Saving Time ends on the first Sunday of November, and begins on the second Sunday in March. Not all places in the United States observe Daylight Saving Time. In particular, Hawaii and most of Arizona do not use it, so if you live in those areas, you don’t have to change your clocks.
Standard time was instituted in the United States and Canada by the railroads in 1883, however, Daylight Saving Time was not established in U.S. law until the Act of March 19, 1918, sometimes called the Standard Time Act.
