I'm struggling to create a 2 shift (2nd shift) calendar in MS Project that calculates correctly.

I want to be able to enter a "2 Shift" calendar for my resource and have a 16 hr work day (two 8 hour shifts). When I enter 8 hours it should calculate .5 days duration. When I switch the calendar back to standard it should be 1 day for 8 hours work.

Could someone help with this? Maybe post a MS Project 2010 file with the calendar created so I can see it?

Much appreciated
