The "spring forward" mnemonic device will once again feature prominently at 2 a.m. on Sunday as Daylight Saving Time kicks in across most of the United States.

The best way to stay current will be to set your clocks one hour forward before you go to bed on Saturday night, KRTV recommended.

The adjustment also known as "summer time" is observed in all U.S. states except Hawaii and Arizona, though Navajo-administered regions do move their clocks forward in the Grand Canyon State, as well. The District of Columbia will switch to Eastern Daylight Time, while the U.S. territories of American Samoa, Guam, Puerto Rico and the Virgin Islands do not adhere.

NASA credits one of America's favorite founding fathers, Benjamin Franklin, with having invented the largely unpopular practice; his idea was to "make the best use of daylight hours by shifting the clock forward in the spring and backward in the fall," the space agency explained.

While most Americans will lose an hour of sleep this weekend, many Europeans will not do so until March 29 -- the month's last Sunday. That is when the clocks will be adjusted in France, Germany, Greece, Italy, Spain and the United Kingdom, among other countries.

In South America, meanwhile, many nations do not observe Daylight Saving Time, and no changes will take place in Argentina and Chile, for example. Uruguay, meanwhile, reverts to Standard Time this Sunday, and Brazil already did during February's Carnival week.

The lost hour of sleep the change imposes is an inconvenience to many, but for some it can carry surprisingly serious health consequences, CBS News noted. Yoseph Krespi, the director of the Center for Sleep Disorders at New York's Lenox Hill Hospital, told the channel that those 60 minutes may amount to more than most suspect.

"People think that moving the clock forward and backward is not a big deal, but in reality it is," Krespi said. "It can change the sleep cycle and the disrupt the opportunity to get a restful sleep."

But Evalina Grayver, the director of the Coronary Care Unit at Long Island's North Shore University Hospital, said there were also some health benefits.

"I think it's a good thing when we have Daylight (Saving) because it will encourage people who have been more sedentary during winter months to get out and be more physically fit," Grayver argued.
