Scheduling does not take the factory calendar for counting the workdays

I am scheduling my jobs in CPS 8 and I have imported my Factory calenders also. When using Factory calendars for scheduling the jobs for the 6th working day of every month, Its does not count the Saturday as a working day, where as the calendar I am using has Working day on Saturday.

Why is it so? And is there a way to solve this ?

Please suggest. Any help is appreciated.
