"Current" is an abstraction, that to physicists is defined as the direction of positive charges flowing. Since most currents are actually due to moving electrons, the direction of current by convention is the opposite the way electrons move in a circuit. (Blame Ben Franklin for guessing the wrong convention, I think.) Actual moving positive charges (e.g. ions in solution) do move in the direction of "current".
