I think this should work:  
StartDate = system.date.now  
EndDate = system.date.addWeeks(StartDate, 4)

But I get this error:  
Caused by: org.python.core.PyException: Traceback (most recent call last): File “”, line 2, in TypeError: addWeeks(): 1st arg can’t be coerced to java.util.Date

Any ideas?

`StartDate = system.date.now()`
