what are the compelling arguments for Daylights Savings Time?

Hello and Good Morning Everybody,

           I am wondering what the logic is behind having Daylights Savings Time.  Personally speaking, I can not actually see any practical use for it.  Each year people are required to change time twice.  It seems like it has become a practice that is just accepted and done year after year without question.  Not that I mind doing it, I am just curious about any logical basis that may exist for it.

           Any shared insights to this question will be appreciated.

          Thank you

           George
