Night owls and late sleepers alike, you’ve been warned: Sunrise will come a bit sooner Sunday morning. In most parts of the country, Daylight Savings Time, the annual act of setting our clocks one hour ahead and “springing forward,” should take place sometime around 2 a.m. March 13, 2011.

(Residents of Hawaii, Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas, you’re excused.)

Year after year, setting our clocks one hour ahead comes the inevitable, split-second gripe in which we mourn that lost hour — sometimes this comes in 140-characters or less.

Although more than 1 billion people around the world observe DST in one form or another, that yearly switch always seems universally unpopular. Consider Indiana, the most recent state to make the change: it was only after a hard-won legislative battle — more than two dozen similar bills were killed before DST passed — that Hoosiers switched over.

Why do we dislike Daylight Savings Time so much? Is it even necessary? (And remember, sometimes the change isn’t all that bad: if you’re in the District, you can technically stay out until 4 a.m. tonight.)
