If everyone doesn't bring up their best prospects to avoid the super 2 designation, that date gets pushed back every year.
The days of service time in the players first year has gone down from 146, to 139, to 119 in the last 3 years. This assuming that a player stays in the majors once he's brought up.
In any event, it's not an exact date.
