Why did daylight saving time (DST) start, and why does it still  continue? When asking a random sample of people we heard two answers  again and again: "To help the farmers" or "Because of  World War I ... or was it World War II?"  In fact, farmers generally oppose daylight saving time. In Indiana,  where part of the state observes DST and part does not, farmers have  opposed a move to DST. Farmers, who must wake with the sun no matter  what time their clock says, are greatly inconvenienced by having to  change their schedule in order to sell their crops to people who observe  daylight saving time.
Daylight saving time did indeed begin in the United States during World  War I, primarily to save fuel by reducing the need to use artificial  lighting. Although some states and communities observed daylight saving  time between the wars, it was not observed nationally again until World  War II. 
Of course, World War II is long over. So why do we still observe daylight saving time? 
The  Uniform Time Act  of 1966 provided the basic framework for alternating between daylight  saving time and standard time, which we now observe in the United  States. But Congress can't seem to resist tinkering with it. For  example, in 1973 daylight saving time was observed all year, instead of  just the spring and summer. The current system of beginning DST at 2 AM  on the first Sunday in April and ending it at 2 AM on the last Sunday in  October was not standardized until 1986.
The earliest known reference to the idea of daylight saving time comes  from a purely whimsical 1784 essay by Benjamin Franklin, called "Turkey  versus Eagle, McCauley is my Beagle." It was first seriously advocated  by William Willit, a British Builder, in his pamphlet "Waste of  Daylight" in 1907. 
Over the years, supporters have advanced new reasons in support of DST,  even though they were not the original reasons behind enacting DST. 
One is safety. Some people believe that if we have more daylight at the end of the day, we will have fewer accidents. 
In fact, this "benefit" comes only at the cost of less daylight in the  morning. When year-round daylight time was tried in 1973, one reason it  was repealed was because of an increased number of school bus accidents  in the morning. Further, a study of traffic accidents throughout Canada  in 1991 and 1992 by  Stanley Coren of the University of British Columbia  before, during, and immediately after the so-called "spring forward"  when DST begins in April. Alarmingly, he found an eight percent jump in  traffic accidents on the Monday after clocks are moved ahead. He  attributes the jump to the lost hour of sleep. In a letter to the New  England Journal of Medicine, Coren explained, "These data show that  small changes in the amount of sleep that people get can have major  consequences in everyday activities." 
He undertook the study as a follow up to research showing that even an  hour's change can disrupt sleep patterns and "persist for up to five  days after each time shift." Other observers attribute the huge spike in  accidents on the first Monday of DST to the sudden change in the amount  of light during driving times. Regardless of the reason, there is no  denying that changing our clocks has a significant cost in human lives.  
While some people claim that they would miss the late evening light, a  presumably similar number of people love the morning light. And  projects, postponed during the sun-filled summer, will be tackled with  new vigor when the sun sets an hour earlier each day. 
Congress appears to have felt we were not having enough of a difficult time so in 2007 they passed a law starting  Daylight Savings time  3 weeks earlier and ending it one week later. This cost US companies  billions to reset automated equipment, put us further out of sync with  Asia and Africa time-wise, inconvenienced most of the country, all in  the name of unproven studies that claim we save energy.
