The loss of an hour in March is hard on a lot of people. It is particularly hard on those who are battling winter depression. After March 9, according to the clock, sunrise will come as late as it did at the end of December, during the darkest days of the year. Sure, we also get an hour added on at the end of the day, but that’s no help. It is early morning light that our inner clocks rely on to keep in sync with the external world.
