FOF utility request

[albionmoonlight]

Have a utility where if you put in the birthday of your position group leader, it spits out the range of birthdays that conflict with that leader and the range of birthdays that have an affinty with that leader.

If someone could make that, I would be very happy.

(I know this is something that I could do with pencil and paper, but I would prefer to do it on the cpu because I am a lazy, lazy man).
