Remember to set your clock ahead 1 hour this March 9th!

Daylight Saving Time is a way of getting more out of the summer days by advancing the clocks by one hour during the summer. The sun will appear to rise one hour later in the morning when people are usually asleep, and allow for extra daylight in the evening hours when people are coming home from work and school. Daylight Savings Time could also save energy and make the country more efficient.Benjamin Franklin suggested the method in 1784 but it did not catch on until World War I, in 1916 in several counties in Europe. Daylight saving time was adopted in the United States in 1918, but was repealed in 1919. It was re-established nationally early in World War II, and was continuously observed from February 9, 1942 to September 20, 1945. After the war its use varied among states. The Uniform Time Act of 1966 provided standardization in the dates of beginning and end of daylight time in the U.S. but allowed for local exemptions from its observance. The act provided that daylight time begin on the last Sunday in April and end on the last Sunday in October, with the changeover to occur at 2 a.m. local time.During the "energy crisis" years, Congress enacted earlier starting dates for daylight time. In 1974, daylight time began on January 6 and in 1975 it began on February 23. After those two years the starting date reverted back to the last Sunday in April. In 1986, a law was passed permanently shifting the starting date of daylight time to the first Sunday in April, beginning in 1987.

On August 8, 2005, President George W. Bush signed the Energy Policy Act of 2005. This Act changes Daylight Saving Time in the U.S. Beginning in 2007, DST will begin on the second Sunday in March and end the first Sunday in November.

It should be noted that not all countries and states observe Daylight Savings Time.
