Hi,
You did not mention your version of Project: I'll describe how to do it in versions 2007 and later.
Open the Change Working time dialog.
Make sure the name displayed is the one of the Calendar you want to change (Standard I presume)
Click the pad "Work Weeks"
Click "Details"
In the upcoming window select Sunday
check Set day(s) to these specific workig times
Enter the working times for Sunday
Now select Friday
Check Set days to nonworking time
OK
OK
There you are.
Greetings,
