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. If you want more information, visit Andy Woodruff’s blog for more information and an interactive version of the map.
