Standard time returns this weekend, so set your clocks back an hour Saturday night.

Most Americans will get an extra hour of sleep, but those working overnight shifts will toil an hour longer. It also means some will forget to change their clocks, and will show up an hour early for church or other events on Sunday.

The time change doesn’t apply in Arizona, Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Mariana Islands.
