Daylight saving 2013 means a time change is coming on Sunday.
For most Americans, that means daylight saving time will end with a fall back to standard time.
At 2 a.m., people will turn back the clocks.
The federal government doesn’t require the time change, which means that some states and territories don’t participate.
Those are Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
Daylight saving time varies around the world, with some countries doing similar clock turns and others none at all.
Albania, Andorra, Austria, and Belgium, for instance, turned back the clocks on Oct. 27.
Canada, Bermuda, Cuba, and Haiti are among the countries that are also turning the clocks back this Sunday, November 3.
And Japan, Kuwait, Nigeria, and Russia are among the countries that don’t have the daylight saving time this year.
