Note that the default calendar is ‘4×10 Work Week’, which is what we want. In the bottom details we select the Defaults tab to view all the default settings for our project. In Figure 2 we view the default settings for our project. Let’s troubleshoot to find out why our Gantt chart is not displaying a 4 day work week. So something is not quite right with our schedule Gantt chart.

Friday, which according to our calendar, is a non-work day, but it is not shaded out. Also, despite the fact that all our activities are assigned a ‘4×10 Work Week’ calendar, which is a 4-day and 10-hour per day schedule, our Gantt chart is only shading Saturdays and Sundays. Note that activities may be assigned different calendars in the same schedule. In Figure 1 we have our ‘Pipe Repair & Improve’ project where all activities are assigned a ‘4×10 Work Week’ calendar. Let’s proceed with our demonstration project called ‘Pipe Repair & Improve’, Figure 1.
