Which calendar is used for Latest end?

["Schröder, Ute Marion"]

Hi everybody,

I just received a question I was unable to answer
and looking in the book didn´t help me either.

If I have a Latest End defined in my workflow-Step, 3 Days after Workitem
Creation, which calender is uded to determine when 3 days are over.

Will say, if the workitem is created on friday, is 3 days later a monday or
would it be a wednesday? 

Is there a way to determine which calender is to be used?

Thanx for all our help,

ute
