Work Days have a white background and non-workdays have a grayed out background in Calendar Views, so it's easy to see days that should and shouldn't typically have activities scheduled.
You can schedule Activities even on non-work days, but you can't set a start time before your Scheduling Hours start or set a duration that would cause them to end after your Scheduling Hours.
Scheduling Hours include Work Hours, it is the largest range of time that things might get manually put on the Calendar.
Work Hours are different, they determine when Activities can be automatically added based on other Activities. Auto-schedule Activities can only be scheduled within Work Hours, even if Scheduling Hours are different.
If you leave the time empty on an Activity or Appointment, it will display as Unscheduled in Calendar Views that show time details.
