Daylight saving time (or DST for short) is the process by which clocks are moved forward one hour in the beginning of spring. The reasoning behind this shift in time is that it provides the traditional business people an extra hour of daylight at the end of a workday as well as saving on power consumption because of the “extra” hour. The United States began observing DST in 1918, but stopped after the war until the energy crisis of the 1970’s when they began to use it again. Those regions that observe DST are actually in the minority as the Asian and African continents do not observe the shift in time. DST faces much opposition and many nations are pushing for its use to be discontinued. The original reasons for DST allowed it stay lighter out longer when people were awake so less energy was consumed lighting homes and businesses. In today’s world there is no shortage of electricity and the way in which buildings are illuminated, heated, and cooled have changed.
