Time changes seem to throw us all of for a day or two. At least it does me. The sun looks out of place in the sky, you feel tired, things are just a little bit out of place.
During late Winter we move our clocks one hour ahead and "lose" an hour during the night and each Fall we move our clocks back one hour and "gain" an extra hour. But Daylight Saving Time (and not Daylight Savings Time with an "s") wasn't just created to confuse our schedules.
