I want to make 3 different calanders for a project which needs to be 8hrs/5day working, 12 Hrs/6day working and 24hrs/7day working. In the "Time Periods" section of each calander what values i should use for Hours/Day, Hours/Week, Hours/Month and Hours/year for each calendar? In the Global calader available on our system it is showning same values for all type of calenders. Is this the correct approch?

leave this setting as is only change the calendar
