What exactly is daylight savings?  Is it necessary and who decides which weekend will be the weekend?  Why don’t all the states participate in the changing of the hour?  I have never completely understood the point of daylight savings.  I have heard many reasons for its necessitybut still don’t know why we do it.  I hate having it get dark so early and light by 6:00 a.m.  It messes with the sleeping habits of my children not to mention my own.  The one thing I really don’t understand is why not all the states participate.  What is even stranger is that only parts of Arizona participate.  Talk about confusing.  The only good thing that will come from this weekend’s time change is the extra hour of sleep you have the opportunity to get.
