… with the following comment: “Here in Boston, lots of folks are mourning the loss of Daylight Saving Time, destined for a 4:12 p.m. sunset in about a month. Wouldn’t it be wonderful to have permanent Daylight Saving Time?
Sadly, there’s lots of opposition to permanent DST, with lots of it coming from 900 counties that enjoy the equivalent of Daylight Saving Time during the winter and (except for Arizona) double DST in the summer.
Time zones are based on 15 degree intervals from Greenwich, England, creating natural solar boundaries between the midpoints of the time zones. In the Lower-48, there are 900 counties that attach themselves to the time zone east of the natural division. This includes a majority of counties in states such as Ohio, Indiana, Michigan, North Dakota, and Texas.”
