Need help with iCal

[Ety]

I am trying to put my schools schedule into iCal and I can't find a way to do it. It's basically Days A-H each day it goes to the next letter day and on vacation days it should just go to the next day and keep going. What is the easiest way to make it work? I was think I will have to write something in Automator or something like that.

Thanks
