     The idea of daylight saving time started with an American named Benjamin Franklin (1706-1790). He

explained how a lot of the money spent on candles used for light (this was before electricity) could be saved

if everyone woke up earlier and went to bed earlier.

     Even though Franklin's idea had a clear meaning, most people didn't want to get up earlier than they had

to. Who would?

     It was not until 1907 that an Englishman named William Willet came up with a way to "make" the sun set

later. His idea was to turn clocks forward by 20 minutes on each of the four Sundays in April, for a total of

80 minutes.

     William's idea was laughed at, at first. But when World War I started in 1914. Many countries decided they

had to save energy for the war.

     Daylight saving time has other uses. The more time you spend outside playing, the less time you are spending

in front of the computer or the TV. These things also use energy.

     Also, daylight saving time sometimes causes problems. For example, China used it in 1986-but stopped it in

1991. That was because me temperatures are quite different from North to South and time from East to West.

     If the people from northwest part of China use daylight saving time. sometimes they have to get up to work

when it is not very bright outside. That will cause some trouble for them.

     Still, most parts of the world do have daylight saving time, and most people look forward to the extra hour

of evening light.
