Check your clocks. Last night, most of us lost an hour of sleep in the U.S. because we switched to Daylight Saving Time. There are only a few exceptions like Hawaii and parts of Arizona. Like most change, there are complaints and haters. There’s even a bill in the California legislature to drop Daylight Saving Time in the Golden State. However when the days warm up, you’ll fine very few grumbling about the extra hour of daylight.
