12 Fun Facts About Daylight Saving Time 1. Officially, its daylight saving time, not daylight savings time. But dont feel bad if you thought there was a final s on saving; far more people Google the incorrect phrase than the correct one. 2. Daylight saving time has mixed effects on peoples health. Transitions into and out of DST can disturb peoples sleeping patterns, for example, and make them more restless at night. Night owls tend to be more bothered by the time changes than people who like mornings, Finnish researchers concluded in 2008. 3. Theres a spike in heart attacks during the first week of daylight saving time, according to another study published in 2008. The loss of an hours sleep may make people more susceptible to an attack, some experts say. When daylight saving time ends in the fall, heart attacks briefly become less frequent than usual. 4. People are safer drivers during daylight hours, and researchers have found that DST reduces lethal car crashes and pedestrian strikes. In fact, a study concluded that observing DST year-round would annually prevent about 195 deaths of motor vehicle occupants and about 171 pedestrian fatalities. 5. The Energy Policy Act of 2005, signed into law by President George W. Bush, extended the length of daylight saving time by four weeks. It now begins at 2 a.m. on the second Sunday in March. It ends on the first Sunday in November. 6. Also in 2005, Kazakhstan abolished daylight saving time, citing negative health effects. The countrys government reportedly calculated that 51.6 percent of Kazakhs responded badly to the time change. 7. Many other countries observe daylight saving time, but not all do so on the same day. That can create confusion for international travelers, business communications, and more. 8. Daylight saving can also cause confusion close to home. In March 2007, a Pennsylvania honor student was mistakenly accused of threatening his school with a bomb. He had actually called an automated line to get info about scheduled classes. Someone else made the bomb threat an hour later. 9. Two states—Arizona and Hawaii—and four U.S. territories—American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands—dont observe daylight saving time. Indiana adopted DST in 2006. 10. Daylight saving time was first used during World War I, as part of an effort in the United States and other warring countries to conserve fuel. In theory, using daylight more efficiently saves fuel and energy because it reduces the nations need for artificial light. 11. The first American to advocate for daylight saving was Benjamin Franklin. He realized in 1784 that many people burned candles at night yet slept past dawn in the summer, wasting early-morning sunlight. 12. The effect of DST on energy use has changed over time and varies from place to place. Experts even disagree on whether DST still saves the nation energy. But so many people like to spring forward that it might be hard for officials to end the tradition, even if they determined its wasteful.
