It’s that time again… This Sunday, we have to turn our clocks back an hour. To be precise, the change comes at 2 AM.

We’ve been doing this off and on since 1918, supposedly to make better use of natural sunlight. The U.S. Senate actually passed a bill early this year making Daylight Saving Time permanent, meaning no more messing around with the clocks. But the bill hasn’t yet gotten through the House.
