We increasingly hear arguments advocating for extending Daylight Saving Time year-round in the United States, mostly on an environmental basis: if DST saves energy, why not make it permanent, and thereby reduce national GHG emissions?

  1. I am still a child at heart, and think that the time of the day ought to have a meaning, all things being equal. Noon is when the sun is overhead.
