I am building a SharePoint designer worklfow (2010 mode). I want to be able to determine/calculate the week and month when a workflow is created and use this in the workflow itself.
How can this be achieved?

Weeknumber is a beast, see the example in the WeekDay Function
Month is =MONTH( [YourDate] )
