Five facts about Daylight Saving Time
1. Daylight saving is observed in only 48 states (Hawaii and Arizona are the exceptions) and 78 countries around the world.
2. The thought that turning our clocks back in the fall and ahead in the spring saves energy is false, according to the History Channel.
3. April will mark the 100th anniversary since the first country began observing Daylight Saving. Englishman William Willett pushed for it in his home country in 1907 but Germany began using it first on April 30, 1916.
Weeks later, their World War I enemy began what they termed "summer time."
4. The United States first used it in 1918 but Congress passed a law overturning it a year later. From then until the Uniform Times Act of 1966 was passed, the decision whether or not to use daylight saving was handled by local officials.
5. Only one-third of Americans think Daylight Saving is "worth the hassle", according to a 2014 Rasmussen poll. Two years earlier, 45 percent did.
