I have set the project calendar working hours to 5 hours/day. However then I enter a task with duration of 6 or 7 hours, Project start and finish date are the same day. Finish date should be the next day. If I enter a task duration of 8 hours, finish date is a day later than the start date (calculated correctly). Has anyone encountered this problem? It appears that somewhere Project has a default of 7 hours per day.
