Don’t forget to set your clocks one hour forward before you go to bed this Sunday. Daylight savings time begins on March 9 at 2:00 a.m.

Daylight savings time began in 1918 to preserve daylight hours. However, the federal law was unpopular, and Congress repealed the law in 1919. President Franklin Roosevelt re-instituted daylight savings time during World War II. After the War, daylight savings time became a local matter, applying at the state and local level. Unfortunately, the inconsistent application of daylight savings time caused a lot of confusion. To end the confusion, Congress passed the Uniform Time Act of 1966 to establish a national uniform system. Since 1966, most of the United States observes daylight savings time excluding Hawaii, most of Arizona, and the territories of Puerto Rico, Virgin Islands, Guam, and American Samoa that stay on “standard time” all year long.
