I have created aproject with standard calender. However, later on I need to change the calender with Saturday as half day working (four hour working). I created a separate calender ":Test" where i have allocated 4 hoursworking on Saturdays. I changed Calender of resources to "Test".

Now I was trying to changes the start and end date for a task, which is earlier starting on Monday, to Start on Saturday, It is not accepting this change. It always goes back to standard Calender.

Any solutions.
