The correct term is Daylight Saving (not savingS) Time and it
happens this Sunday for ALMOST ALL of the United States and
other locations in the world…
The concept of Daylight Saving Time was introduced in an 1784 essay written by Benjamin Franklin called “An Economical Project for Diminishing the Cost of Light”; Franklin proposed that using less candles to light the day/night would help to save money during the winter season when natural light is at its shortest.
The idea was again presented in 1895 by George Vernon Hudson and then in 1905 with William Willet. Willet’s plan was presented to the New Zealand House of Commons in 1908 but was not approved. There is evidence that versions and concepts of Daylight Saving Time had been used by ancient civilizations centuries earlier.
DST was first adopted to replace artificial lighting so they could save fuel for the war effort in Germany during World War I and other countries including Britain and the United States soon followed.
In the years that followed, in the U.S., there were problems since states and individual localities were able to set their own dates to observe the time change. Congress resolved the confusion with the Uniform Time Act of 1966 that stated DST would begin on the last Sunday of April and end on the last Sunday of October; however, states still had the ability to be exempt from DST by passing a local ordinance. Changes were made in 1976, 1987 and 2007 in response to the Energy Crisis.
Today DST starts on the second Sunday in March and ends on the first Sunday in November. Currently, most of the US observes DST except for Hawaii and most of Arizona, and the US insular areas of Puerto Rico, the US Virgin Islands, American Samoa, and Guam. More than 70 countries worldwide observe DST.
