Daylight saving time
Daylight saving time (DST) is the practice of advancing clocks during warmer months so that darkness falls later each day according to the clock. DST is generally not observed near the equator, where sunrise and sunset times do not vary enough to justify it. Supporters have argued that DST decreases energy consumption by reducing the need for lighting and heating, but the actual effect on overall energy use is heavily disputed.
About Daylight saving time in brief
Daylight saving time (DST) is the practice of advancing clocks during warmer months so that darkness falls later each day according to the clock. DST is generally not observed near the equator, where sunrise and sunset times do not vary enough to justify it. Only a minority of the world’s population uses DST; Asia and Africa generally do not observe it. Supporters have argued that DST decreases energy consumption by reducing the need for lighting and heating, but the actual effect on overall energy use is heavily disputed. The effect also varies according to how far east or west the location is within its time zone, with locations farther east inside the time zone benefiting more from DST than locations farther west in the same time zone. The German Empire and Austria-Hungary organized the first nationwide implementation of DST starting on April 30, 1916. Benjamin Franklin published a letter as an American envoy to Paris during his time as an envoy to France suggesting that Parisians economize on candles by rising earlier to use more sunlight. In 1810, the Spanish National Assembly issued a regulation that required a standardization of time in Europe. Despite common misconception, Franklin did not actually propose DST in the 18th-century; he did not even keep precise schedules in Europe at the time of his time. He did, however, publish a letter to Parisians in the Journal de Paris suggesting that early rising and early to bed makes a man healthy, wealthy, and wise, and suggested that the Parisians use window shutters, rationing candles and waking the public by ringing the public bells at sunrise and firing the public cannons at sunrise.
In the 19th century, the Spaniard Cádiz issued a resolution that required the National Assembly of Spain to standardize time in a number of areas, including Spain, France, Italy, and the Netherlands. The Spanish Assembly issued the resolution in 1810; it was not until 18th century that the Spaniards standardized time in all parts of the country, and it was only in Spain that they began to use DST. The Spaniard’s resolution was the first time DST was used in Europe; it is still used in a few settings, such as monasteries of Mount Athos and all Jewish ceremonies. The United States observes DST, while Arizona does not. The U.S. is one of the few countries that does not observe daylight saving time, although it does observe it in some areas such as New Jersey and New York City. The European Union does not use daylight savings time at all; it only observes it in certain regions such as the Netherlands, Belgium, France and Germany. The EU also observes daylight saving in the summer and in the autumn. The time of day that individuals begin and end work or school, for example, usually remain constant year-round. In contrast, an agrarian society’s daily routines for work and personal conduct are more likely governed by the length of daylight hours and by solar time, which change seasonally because of the Earth’s axial tilt.
