Did you set your clock back this weekend? Why do we change our clocks anyway, and is it even necessary anymore? Some critics say no.
If you thought switching your clocks back was a hassle, imagine owing a clock shop filled with hundreds of them!
"A lot of work!", said Teri Miller of Weil Clocks in Allentown. "A lot of work to set all of them, yes."
So did you fall back to Standard Time yet?
"No," said Doug Harwick of Coopersburg. "My phone did it automatically though."
So why do we engage in this time-consuming ritual twice a year, every year?
"I have no idea," said Miller.
Ben Franklin first came up with the idea, but it wasn't until World War One that it stuck -- as a plan to save energy in the summer.
"Uh huh, that makes sense," said Harwick.
But in this modern era, is all this clock-switching even necessary anymore? Some people think the practice is a little cookoo.
"I don't see the purpose of it," said Erick Huertas of Center Valley. "I just do it because everyone else does it."
Turns out, studies find the power savings are negligible. California's Energy Commission found the switch only saves half a percent of electricity a year, and when Indiana adopted Daylight Savings Time in 2006, energy use actually went up one percent.
"Why they don't just leave it that way all year?", asked Miller. "It could save some problems."
It's a question we all got an extra hour to think about.
