So, does Daylight Saving Time (DST) really have an advantage? Andy Woodruff has produced a map that begs the question, and probably answers it as well. In two sets of maps, we can compare the reasonable sunrise times (defined as before 7 a.m.) and reasonable sunset times (defined as after 5 p.m.) between DST and non-DST. First up, we have the DST maps:
As you can see, the closer you live to the edge of a time zone, the worse the effects are. But for most of the population, you will have some mornings where the morning doesn’t officially start until after 7 a.m. Now for the non-DST maps:
The difference? The evening times stay about the same, but there is a cost in morning hours. I can’t see how we are saving a lot of resources by implementing DST, but it certainly does add to the confusion.
