Different class hours / break times

[k1aas]

Hello, I was pleasantly surprised to discover FET. I'm sure it will be a big help in defining timetables in our KG/primary/junior-high school.

Some questions:
- Our Friday timetable is different than during the other days of the week (lessons and breaks start at a different moment etc.)
- We have different (half-hour) break moments for different classes.

How do I specify these variations?

- Our Friday timetable is different than during the other days of the week (lessons and breaks start at a different moment etc.)

Take greatest common divisor of lengths. This is a FET hour. For instance, Monday: 45 minutes, Friday: 30 minutes. Then FET "hour"=real 15 minutes. Edited to add: an activity of 2*45 minutes on Monday will have duration 6 FET hours and an activity of duration 1*30 minutes on Friday will have duration 2 FET hours

- We have different (half-hour) break moments for different classes.

Constraint students set not available (if you know the exact slot), or an activity with no teachers for each students set (class).
