OK so I'm going to start working on the two week timetable stuff, so wanted to know what people need from it, as I've never used a two week timetable so don't know the intricacies of it.
What I'm thinking so far, and please correct anything I have wrong or should be a variable not a defined setting, is:

[LIST][*]General settings option asking whether a one or two week timetable. If 1 week, all further options are removed, otherwise.....[*]When adding an academic year, the first week of that year is always set as week 1[*]When adding a holiday, the option will be there to specify which weeks timetable will start after the holiday[*]It will be assumed that both weeks have the same number of periods, and are exactly alike in every respect apart from which lessons are scheduled

Is there anything else a two week timetable should have or options that should be given?
