If you're more noticeable the further north you are, but it is an ongoing debate for each country. It would be nice if it could be decided for everywhere. You know that Europe and America don't have the same days for the start of Summer Time!
I didn't know that.. all I know is it sucks having the sun go down rught after I get out of work, and losing an hour of sleep in the spring. I live in Fl., by the way. Must be worse for those up north.
