OK, so I'd done a simple macro that sets current Year and Month as a document is opened. I was looking for a solution here in the community and couldnt find it so I thought I might share my solution with you.
You could offcourse use this macro to set other variables...like current date for instance.

Sub initDate
'*************************************************************************************
'Macro name: initDate
'This macro sets current Year and Month - Trigger on event "When document opens"
'Event Trigger is set manually in Document-properties / Triggers
'1. Choose trigger "When document opens"
'2. Add activity
'3. Under activity, choose ”Add” + ”Extern” + ”run macro” + enter ”initDate”
'**************************************************************************************
'Set current Year - Change "datum_Year" to your corresponding Year-field
ActiveDocument.GetField("datum_Year").Select ActiveDocument.Evaluate("year(today())")
'Set current Month - Change "datum_Month" to your corresponding Month-field
ActiveDocument.GetField("datum_Month").Select ActiveDocument.Evaluate("num(month(today()),00)")
End Sub
