When to turn the clocks back in 2018, ending Daylight Saving time?

CLEVELAND, Ohio - Clocks turn back an hour at 2 a.m. on Sunday, Nov. 4, marking the end of Daylight Saving Time.

This means it will get dark an hour earlier each day.

As a result of the change to Standard Time, sunset in Cleveland will be at 5:18 p.m. on Nov. 4, instead of 6:18 p.m. without the change, according to the U.S. Naval Observatory.

Sunrise will be 7:02 a.m. instead of 8:02 a.m.

It will keep getting darker earlier for a few weeks. Sunset will be as early as 4:57 p.m. in Cleveland from Dec. 2 through Dec. 14. Sunset will be as late as 9:04 p.m. from next June 20 through July 4.

Standard time will be used through March 11, when clocks will “spring” forward an hour to begin Daylight Saving Time.

In an oddity, Standard Time is not the norm.

About two-thirds of the days during the year operate on Daylight Saving Time. The rules last changed in 2007, the result of the Energy Policy Act of 2005. The change was an effort to reduce energy consumption, according to the National Institute of Standards and Technology.

Daylight Saving Time now begins on the second Sunday of March each year and ends on the first Sunday of November.

DST has roots tracing to 1918 in the United States, though not all places always observed it. Currently, it is not used in Hawaii and most of Arizona.

It’s also not observed in American Samoa, Guam, Puerto Rico and the Virgin Islands.
