Date window
PremiumA date window is a reusable date inclusion or exclusion period that restricts when certain lessons can be scheduled. Defined once on the edit screen of a calendar timetable, it then applies as an overlay on the time constraints of classes, groups and courses as well as on the availability of classrooms.
Reserved for calendar-type timetables, on Premium accounts.
Two types
- Allowed lessons — lessons can only be scheduled during these dates.
- Excluded lessons — lessons cannot be scheduled during them.
Multiple windows stack; where they overlap, an exclusion takes precedence over an allowed period.
