I'm not entirely sure I understand your question, but it sounds to me like you 
want to use date generators.  These allow you to specify part of a date and 
then generate a concrete date based on a final input.  For example you can say

partial_date pd(20, Jan);
date d = pd.get_date(2007);

Is that what you are trying to do?  Anyway, the docs for this stuff are at:
