You could define month and/or day as 1, if that is appropriate for your data needs, when they are left out (2008 -> 1/1/2008, 5/2008 -> 5/1/2008)...

If the date is in a numeric format, it cannot be missing a month (numeric Date = days since a particular day, IIRC 1/1/1960 for SAS). If you mean character format with numbers inside, then you would have to make reasonable guesses for what is missing (is 092008 Sept. 2008 (no date), or 9/20/2008, or julian 1/9/2008, or something else?)
