Time to fall back

(CNN) -- People in most of the United States ''fall back'' to standard time early Sunday when daylight saving time ends at 2 a.m. local time. It means getting back the hour of sleep lost when daylight saving time began in April.

As the saying goes, spring forward, fall back. Forget, and you will be an hour early for church, work or whatever.

The idea for daylight saving time reportedly was first suggested by Benjamin Franklin, but the idea wasn't instituted until World War I to save energy used for lights.

It's not universally popular, though. Farmers note that their livestock don't live by a clock, and complain that they have to adjust their working hours to deal with the animals.

As a result, the use of daylight saving (not "savings") time was made a local option after World War II. Changing time proved more popular in some areas than others.

But the result was confusion, because time changed from state to state and even city to city.

Broadcasters, railroads, airlines and others complained and the government established the Uniform Time Act of 1966 to institutionalize the time changes.

Additional federal legislation in 1986 set daylight-saving time to begin at 2 a.m. on the first Sunday of April and end at 2 a.m. on the last Sunday of October.

States and localities can still opt out, however, and some have. Arizona, Hawaii, the part of Indiana in the Eastern time zone, Puerto Rico, the Virgin Islands and American Samoa remain on standard time year-round.

Daylight saving time returns April 2.
