Current Daylight Saving Time (DST) or "summer hours" is now a majority of the year. DST is in effect for 238 days, or about 65% of the year. Remaining on Standard Time (ST) the remainder of the year offers little benefit in nearly half the country due to differences in day length due to latitude. The transition from DST to ST effectively moves one hour of daylight from the evening to the morning, but in northern parts of the U.S. in the winter, many citizens commute to work in the dark and return home after work in the dark, even with the change to ST.
Time to eliminate the change to ST and remain on DST all year, eliminating the overhead of the change, by not switching in Autumn of 2015.
