Please help me it is for school!!!!!!!!?

Question

why do we have daylight savings what is it for.

Answer 1

It is so that people's internal time clocks will be disrupted.

Answer 2

The idea is to allow people to work in daylight. Because the rising and setting of the sun changes during the year, daylight savings was created to move the start of the work day into the daylight hours.

It is not as useful as it was long ago when factories used natural lighting and work could not be done without it. Today many people work in offices that have no windows and therefore only care about need to use their headlights on the way to work.

One issue that occurred years ago when they changed the start of daylight savings was the concern that school children were waiting for their school buses in the dark.

Answer 3

Originally, daylight savings time was put into place as a wartime measure during World War 2. The idea was that by setting the clocks forward an hour in the spring it would help to reduce energy use (especially oil for powrplants) and give people more daylight hours to do things in the evening--War bond drives, "victory gardens" and so on. It was one of a multitude of measures put in place to hold down consumption and increase production for the war effort.

Most of those things wen't by the board after the war, of course--nobody LIKED rationing, for instance. But the idea of daylight savings time proved to be popular--most people like having that extra hour of daylight in the evening whn the weather starts to warm up. So the idea--originally a temporary measure--stuck.

Answer 4

One of the biggest reasons we change our clocks to Daylight Saving Time (DST) is that it saves energy. Energy use and the demand for electricity for lighting our homes is directly connected to when we go to bed and when we get up. Bedtime for most of us is late evening through the year. When we go to bed, we turn off the lights and TV.

In the average home, 25 percent of all the electricity we use is for lighting and small appliances, such as TVs, VCRs and stereos. A good percentage of energy consumed by lighting and appliances occurs in the evening when families are home. By moving the clock ahead one hour, we can cut the amount of electricity we consume each day.

Studies done in the 1970s by the U.S. Department of Transportation show that we trim the entire country's electricity usage by about one percent EACH DAY with Daylight Saving Time.

Daylight Saving Time "makes" the sun "set" one hour later and therefore reduces the period between sunset and bedtime by one hour. This means that less electricity would be used for lighting and appliances late in the day.

We also use less electricity because we are home fewer hours during the "longer" days of spring and summer. Most people plan outdoor activities in the extra daylight hours. When we are not at home, we don't turn on the appliances and lights. A poll done by the U.S. Department of Transportation indicated that Americans liked Daylight Saving Time because "there is more light in the evenings / can do more in the evenings."



While the amounts of energy saved per household are small...added up they can be very large.

In the winter, the afternoon Daylight Saving Time advantage is offset by the morning's need for more lighting. In spring and fall, the advantage is less than one hour. So, Daylight Saving Time saves energy for lighting in all seasons of the year except for the four darkest months of the year (November, December, January and February) when the afternoon advantage is offset by the need for lighting because of late sunrise.

Answer 5

Daylight Saving Time (or summertime as it is called in many countries) is a way of getting more light out of the day by advancing clocks by one hour during the summer. During Daylight Saving Time, the sun appears to rise one hour later in the morning, when people are usually asleep anyway, and sets one hour later in the evening, seeming to stretch the day longer. The reason DST works is because its saves energy due to less artificial light needed during the evening hours—clocks are set one hour ahead during the spring, and one hour back to standard time in the autumn. Many countries observe DST, and many do not.

Note: Between March–April through September–November, it is summer in the northern hemisphere, where many countries may observe DST, while in the southern hemisphere it is winter. During the rest of the year the opposite is true: it is winter in the northern hemisphere and summer in the southern.

Answer 6

Daylight saving time (DST), also known as summer time in British English, is the convention of advancing clocks so that evenings have more daylight and mornings have less. Typically clocks are adjusted forward one hour in late winter or early spring and are adjusted backward in autumn. Details vary by location and change occasionally; see Observation below.

Answer 7

Rationale and original idea
The main purpose of Daylight Saving Time (called "Summer Time" in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening. Countries have different change dates. Glide your cursor over the map to see how changing the clocks affects different latitudes.



If you live near the equator, day and night are nearly the same length (12 hours). But elsewhere on Earth, there is much more daylight in the summer than in the winter. The closer you live to the North or South Pole, the longer the period of daylight in the summer. Thus, Daylight Saving Time (Summer Time) is usually not helpful in the tropics, and countries near the equator generally do not change their clocks.

A poll conducted by the U.S. Department of Transportation indicated that Americans liked Daylight Saving Time because "there is more light in the evenings / can do more in the evenings." A 1976 survey of 2.7 million citizens in New South Wales, Australia, found 68% liked daylight saving. Indeed, some say that the primary reason that Daylight Saving Time is a part of many societies is simply because people like to enjoy long summer evenings, and that reasons such as energy conservation are merely rationalizations.

However, Daylight Saving Time does save energy. Studies done by the U.S. Department of Transportation show that Daylight Saving Time trims the entire country's electricity usage by a small but significant amount, about one percent each day, because less electricity is used for lighting and appliances. Similarly, in New Zealand, power companies have found that power usage decreases 3.5 percent when daylight saving starts. In the first week, peak evening consumption commonly drops around five percent.
Energy use and the demand for electricity for lighting homes is directly related to the times when people go to bed at night and rise in the morning. In the average home, 25 percent of electricity is used for lighting and small appliances, such as TVs, VCRs, and stereos. A good percentage of energy consumed by lighting and appliances occurs in the evening when families are home. By moving the clock ahead one hour, the amount of electricity consumed each day decreases.


In the summer, people who rise before the sun rises use more energy in the morning than if DST was not in effect. However, although 70 percent of Americans rise before 7:00 a.m., this waste of energy from having less sunlight in the morning is more than offset by the savings of energy that results from more sunlight in the evening.

In the winter, the afternoon Daylight Saving Time advantage is offset for many people and businesses by the morning's need for more lighting. In spring and fall, the advantage is generally less than one hour. So, Daylight Saving Time saves energy for lighting in all seasons of the year, but it saves least during the four darkest months of winter (November, December, January, and February), when the afternoon advantage is offset by the need for lighting because of late sunrise.

In addition, less electricity is used because people are home fewer hours during the "longer" days of spring and summer. Most people plan outdoor activities in the extra daylight hours. When people are not at home, they don't turn on the appliances and lights.

There is a public health benefit to Daylight Saving Time, as it decreases traffic accidents. Several studies in the U.S. and Great Britain have found that the DST daylight shift reduces net traffic accidents and fatalities by close to one percent. An increase in accidents in the dark mornings is more than offset by the evening decrease in accidents.

Answer 8

Benjamin Franklin came up with this idea so the working class could work in daylight hours year round, I think.

Answer 9

Origin
Saving daylight was first mentioned in 1784 by Benjamin Franklin in a humorous letter[1] urging Parisians to get up earlier in order to use sunlight, thus saving wax by not burning candles at night, in the spirit of his proverb "Early to bed and early to rise / Makes a man healthy, wealthy, and wise."[2] Franklin did not mention Daylight Saving Time—he did not propose that clock time be changed.

DST was first seriously proposed in 1907 by William Willett,[3] but he was unable to get the British government to adopt it, despite considerable lobbying.

DST was first put into practice by a national government in Germany during World War I, between April 30, 1916 and October 1, 1916. Shortly afterward, the United Kingdom followed suit, first adopting it between May 21 and October 1, 1916. On June 17, 1917, Newfoundland became the first North American jurisdiction to adopt DST with the passing of the Daylight Saving Act of 1917. On March 19, 1918, the U.S. Congress formally established several time zones, which had been in use by railroads and most cities since 1883; at the same time it established DST from the last Sunday in March to the last Sunday in October. The law, however, proved so unpopular, mostly because it obliged people to rise and go to bed earlier than had become customary since the advent of electricity, that it was repealed after 1919, when Congress overrode President Woodrow Wilson's veto of the repeal.


[edit] Observation of DST
In a typical case where a one-hour shift occurs at 02:00 local time, in spring the clock jumps forward from 01:59:59.999… to 03:00 and that day is 23 hours long, whereas in autumn the clock jumps backward from 01:59:59.999… to 01:00, repeating that hour, and the day is 25 hours long. A one hour clock shift is customary, but Lord Howe Island uses a half-hour shift, and twenty-minute and two-hour shifts have occurred in the past.

Clock shifts typically occur near a weekend midnight to lessen disruption to weekday schedules.

Start and end dates and times vary with location and year. Starting in 2007, most of the United States and Canada observe DST from the second Sunday in March to the first Sunday in November, with transitions typically at 02:00 local time. The 2007 U.S. change was part of the Energy Policy Act of 2005; previously, from 1987 through 2006, the start and end dates were the first Sunday in April and the last Sunday in October, and Congress retains the right to go back to the previous dates once an energy consumption study is done. Since 1996 the European Union has observed DST from the last Sunday in March to the last Sunday in October, with transitions at 01:00 UTC.

Beginning and ending dates are switched in the southern hemisphere. For example, mainland Chile observes DST from the second Saturday in October to the second Saturday in March, with transitions at 24:00 local time. The time difference between the United Kingdom and mainland Chile may therefore be three, four, or five hours, depending on the date.

Argentina, Iceland, Saskatchewan and other areas skew time zones westward, in effect observing DST year round without complications from DST shifts. The United Kingdom and Ireland experimented with year-round DST from 1968 to 1971 but abandoned it due to its unpopularity, particularly in the north.[4] Alaska, France, Spain and other areas both skew time zones and shift clocks, in effect observing double (or more) DST in summer.

DST is generally not observed near the equator, where day lengths do not vary enough to justify it.


[edit] Rationales for DST
Willett's 1907 proposal argued that DST increases opportunities for outdoor leisure activities during afternoon sunlight hours. As a builder, he also wanted workers to arrive at construction sites earlier in summer mornings. Similar motivations remain to this day.

Energy conservation has often been used to justify DST. The idea is that artificially delaying sunrise and sunset tends to increase energy consumption in the morning and reduce it in the evening. In theory, the evening reduction outweighs the morning increase. United States Department of Transportation (DOT) studies concluded in 1975 that DST would probably reduce the country's electricity usage by 1% during March and April.[5] A study after Mexico reintroduced DST in 1996 estimated national savings of 0.7% of national electric consumption and reduction of peak load by 500 MW.[6]

An energy argument for observing DST in summer rather than winter is that most people wake up after the summer sun rises regardless of whether DST is in effect, so DST during summer has less need for morning electrical lighting.

The above-mentioned 1975 DOT studies also identified a 0.7% reduction in traffic fatalities and a reduction of 10 to 13% in the violent crime rate of Washington, DC. Other studies have also found reductions in traffic fatalities[7][8] which far outweigh the clock-shift increases noted below.
