(Christian Science Monitor) Though swaths of the US are still locked in winter's grip of cold and snow, the time has come for an annual rite of spring: daylight saving.
Daylight Saving Time takes place at 2 a.m. Sunday, when for most of the United States time officially jumps forward an hour to 3 a.m. Exempt from clock-adjusting are Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Marianas Islands. Arizona is the only state that opts out voluntarily.
The federal government does not mandate Daylight Saving Time; states do. In some states, in fact, half the state adopts Daylight Saving Time and the other half does not. As many as 30 bills appear each year in state legislatures in favor either of halting it altogether or of adopting it all year long, Michael Downing, author of "Spring Forward: The Annual Madness of Daylight Saving Time," told the National Geographic Thursday.
