Reminder: Daylight Saving Time ends this weekend

Updated:

PITTSBURGH —

The days are already getting shorter, but sunset is about to arrive an entire hour earlier this weekend when we conclude Daylight Saving Time by dialing the clocks back an hour.

Sunday at 2 a.m., more than seven months of Daylight Saving Time comes to an end.

The act of “springing forward” and “falling back” was first legislated in 1918 in the U.S. and became a long lasting and more uniform practice in the late 1960s.

Since 2007, Daylight Saving Time has begun on the second Sunday in March and come to an end on the first Sunday in November. Arizona, Hawaii and various overseas territories are the exceptions and do not observe DST.

After you adjust all of your clocks, fire safety advocates advise people to replace the batteries in their household smoke and carbon monoxide detectors.
