As I understand it, Daylight savings time is pointless and even occasionally dangerous.
On days after the time switch, studies show that there are more car crashes and other accidents because people are behind on sleep.
Nor does it effectively save energy, because when Indiana went on Daylight savings in the 90s, energy use actually increased.
Daylight savings originated at the beginning of the 20th century when energy use and people's habits of sleeping were completely different.
Finally, since the majority of the world does not use daylight savings, DS makes it more inconvenient for countries to communicate, trade, and travel.
I have a hard time thinking of any positive aspects of DST, and if there are, surely they are outweighed by the many negatives.
