This can be tracked back to World War I, when Congress imposed one standard time on the United States to enable the country to better utilize resources, following the European model.
Northwesterners don't like losing sleep, or turning their clocks ahead every year.
When Benjamin Franklin first developed the idea in line with his "early to bed, early to rise" maxim, he thought it might save candles. Czeisler said that heart attack risk goes up 5 percent and motor vehicle crashes go up 17 percent immediately after Daylight Saving Time starts. But the new Speaker of the Assembly, Anthony Rendon, says he supports Daylight Saving Time.
Clocks and watches will need to be put forward one hour at 2am Sunday morning. It was reinstated during World War II.
Before President Lyndon B. Johnson signed the Uniform Time Act in 1966, which established a uniform daylight saving time, local governments could start and end daylight saving time as they desired.
The time change is not observed in Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas. It also saves about 1% on energy costs.
Thunder Bay first adopted Daylight Saving Time in 1908, making it the first town in Canada to do so.
Other studies found that switching clocks back and forth every year mostly just disrupted sleep patterns, and had very little effect on our health. The town of Creston takes it one step further - setting their clocks to Calgary time in the Winter and to Vancouver time in the Summer. Energy users in IN turned their lights off sooner because of the time shift, but they made up for it by using more energy in heating and cooling, researchers from Yale University and the University of California-Santa Barbara wrote in the Review of Economics and Statistics. But sleep-wake cycles change as people age, so the older people are, the more likely they are to struggle with the time adjustment.
