why do we observe daylight savings time
WhoБs turning the clocks back (or springing forward) with you? БSpring forwardБ and Бfall backБ are seasonal markers for most parts of the countryБ. Daylight Saving Time is not observed in Hawaii or Arizona (with the exception of the Navajo Nation), and itБs also skipped in Puerto Rico and the Virgin Islands. When it comes to the rest of the world, itБs a mix. In fact, only about 70 percent of countries follow Daylight Savings Time. HereБs a rundown of the countries that choose not to mess with their clocks. Much of the Tropics: Many countries along and below the equator donБt participate in Daylight Savings Time. Due to their location, the daylight hours donБt change much from season to season, so thereБs no need to turn their clocks forward or back. However, this isnБt a steadfast rule, as some areas of South America do follow it, including Chili and sections of Brazil. Parts of Australia: In this country, itБs up to the states and territories to decide whether they want to use Daylight Savings Time, which is why БDown UnderБ is divided when it comes to who adjusts their clocks.
Western Australia, Queensland, and the Northern Territory do not observe Daylight Savings Time. Areas of Asia: China, Japan, South Korea, Taiwan, and India do not observe Daylight Savings Time. Iceland: While the European Union and the rest of Europe all change their clocks, Iceland chooses not to. б The Majority of Africa: Most of Africa opts out of Daylight Savings Time, but there are some exceptions, like Egypt, Libya, and Namibia. There has been talk of reintroducing it to South Africa, but as of now, the country does not follow Daylight Savings Time.
Myths, truths, and debates about switching the clocks The terms Бspring forwardБ and Бfall backБ are used to describe a practice of changing standard time with the intention ofб БsavingБ (as in, making better use of) natural light. During daylight savings time (DST), clocks are turned ahead one hour, so that the sun rises later in the morning and sets later in the evening. The change is reversed in autumn.
Originally enacted in the United States as a wartime conservation effort, observance of DST became federal law in 1918. (To dispel a common myth: It was not enacted for farmersБin fact, most farmers fought for its repeal. ) While it was quickly repealed after the war ended, DST was observed nationally again during World War II. By 1966, some 100 million Americans were practicing some type of DST through their own local laws. In 1966, Congress acted to end the confusion and establish one consistent nationwide pattern. The Uniform Time Act of 1966 stated that DST would begin on the last Sunday of April and end on the last Sunday of October. (Any area that wanted to be exempt from DST could do so by passing a local ordinance. ) By 2005, the Energy Policy Act established that DST begins each year on the second Sunday in March at 2:00am and that the changeover back to standard time (ST) occurs on the first Sunday in November at 2:00am. How much difference can an hour make? Opinions about the 60-minute swap tend to be passionate. For instance, proponents say that DST saves energy because in the spring and summer months, more people may be outside in the evening and not using energy (in the form of artificial light) at home.
Some simply relish long summer evenings full of outdoor barbecues, swims, and late sunsets. Opponents say that any energy savings due to using less artificial light have been offset by an increased use of air-conditioning over the past few decades. They also argue that the drawbacks of springing ahead include increased, lost productivity, and a rise in traffic accidents due to during the first few days after the spring time change. Sadly, those traffic accidents can even include cars and bus drivers hitting young students who are walking to their bus stops or standing at them during the dark, early morning hours in the late spring and early fall. Clearly, over the past century or so, the U. S. has had conflicting views about the usefulness of DST. Will DST be around forever? Only time will tell. Not sure how to maximize efficiency during DST?
