what is daylight savings time and what is its purpose?

Answer 1

daylight savings time was established to give farmers more
time to work. it is going to be started earlier this year in order
to conserve energy by extending daylight longer.

Answer 2

Daylight savings time is a clock adjustment that was done to allow for more sunlight at the end of the day. Think of the old addage, "Spring ahead, fall behind". You set your clock 1 hour ahead in the spring on the Saturday night of DST when you go to bed in the spring. Set your clock back an hour the same way in the fall.

The original reason was to save electricity, as people at home would turn their lights on 1 hour later. There are a lot of good reasons. Another benefit is the rush hour traffic is heavier at night than in the morning. The extra sunshine at night during the rush hour has proved that accidents are fewer during the daylight hours.

Answer 3

Daylight Saving Time(not savings) simply saves daylight as it says. It saves the need for power usage by allowing more daylight hours whiel people are usually out doing whatever they wanna do. Instead of it gettign dark at 6:30 or so here ti will now get dark at 7:30, we have an extra hour to do whatever without havgin to run electricity.
It was put into effect first by Germany during World War I as a way to conserve durign shortages.

Answer 4

I've always heard that it was to give farmers more time to work during the growing season but the energy thing makes sense too. All I know is it sure is nice to be able to get stuff done in daylight in the evenings.

Answer 5

in the Fall you fall back an hour and in the spring you spring ahead an hour, it first started off because of the kids waiting for the bus in the dark, because in the early mornings it doesn't get light till almost 7 am now in the mornings, and that is with daylight savings time, normally it would be almost 8 am and schools would be in session. well that is at least the reason in Indiana, and Northern Illinois.

The history of daylight-saving time
1784 - Benjamin Franklin is thought to have come up with the idea for daylight-saving time. In a whimsical letter to a French journal, he said that Parisians could save thousands of francs a years by waking up earlier during the summer because it would prevent them from having to buy so many candles to light the evening hours.

1918 - The U.S. first adopts daylight-saving time, in the same act that created standard time zones, in an effort to save energy during World War I. It didn't prove popular, and, as a result, it was repealed the following year.

1942 - President Franklin D. Roosevelt instituted "war-time," a year-round daylight-saving time to save energy during World War II. After the year-round shift ended in 1945, many states adopted their own summer time changes.

1966 - Congress established a national pattern for summer time changes with the Uniform Time Act. The act came in response from the transportation industry, which demanded consistency across time zones. The U.S. Department of Transportation now oversees time changes in the United States.

1973 - An oil embargo by the Organization of Petroleum Exporting Countries led Congress to enact a test period of year-round daylight-saving time in 1974 and 1975. The test period was controversial; it ended after complaints that the dark winter mornings endangered children traveling to school. The U.S. returned to summer daylight-saving time in 1975.

1986 - The Federal law is amended to start daylight-saving time on the first Sunday in April, beginning in 1987. The ending date of daylight-saving time was never changed, and remained the last Sunday in October through 2006.

2005 - On August 8, President Bush signs the Energy Policy Act of 2005 into law. Part of the act will extend daylight-saving time starting in 2007, from the second Sunday in March to the first Sunday in November.

2007 - Daylight-saving time begins on Sunday, March 11 and ends on Sunday, November 4.
