How to set initial timing using the harmonic balancer and dampener

On my car there's a harmonic balancer w/ the dampener at about 1 or 2 o' clock when looking at the front of the engine and imaging a clockface. On the dampener it goes 12 10 8 6 4 2 0 2 4 6 8 clockwise. On the harmonic balancer there is a degree numbering scheme in 10 degree increments up to 60 with 5-10 notches in between each 10 degree increment. How should 8/10/12/whatever degrees of advance before top dead center get set on this setup? What numbers on the harmonic balancer should line up with which numbers on the dampener?
