9 mm PCB mount vertical pots

These getting hard to find, some of us will be getting whatever we find with the same footprint.

Having never used D-shaft pots + knobs, I have to ask this very basic but fundamental question…

Which way should the pots be mounted on the PCB so the knob’s mark goes from about 7 o’clock to 5, not from 1 to 11 with D-shaft pots ?
Legs “down” or “up” ?
