The good news is if you're a morning person you'll have more light in the morning, but the bad news is that it will get darker earlier. Tonight is daylight savings time, so remember to turn your clocks back one hour at 2 am on Sunday, November 1st, making it 1 am. Of course your smartphones and computers will most likely do it for you. So sunrise and sunset will be about one hour earlier on Nov 1st. Daylight Savings Time was enacted by Congress during World War I and then again during WWII, with the belief it would save on energy costs.
