I'm not sure if this  spreadsheet will work for you.  I don't remember the exact data you wanted,  so I did things from memory.  The dates may not be correct, because I  (multiplied the number of months * 30 days) then added this number to the start  date to project the ending period.  You know our our SAP software  automatically does things like this :)
