Talk to the anime clerk and pay close attention to what he says.
i've already seen him say how old he is, i still don't get it. sorry.
The code is his birthday written as MMDDYY.
His dialogue hints at what the month/day are, so you may have to do a bit of math. Checking Sam's calendar in his room will also tell you the current (in-game) date as reference.
alright, thank you.
edit: the YY should be the last two digits of the year, right?
nevermind, got it. kept thinking it should be the exact month it is at the moment in game.
