too ambiguous?

I need to fix an ambiguous situation: I have the following rules (note that
in italy we use to write sometihn like 1 january 2003, not January, 1
2003!!!):
day_and_month: DIGIT MONTH_NAME
                ;
day_month_and_year: DIGIT MONTH_NAME DIGIT
                ;
only_month: MONTH_NAME
                ;


the problem arises when I insert the input "1 january 3 february", because
the parser undestand I mean a da_month_and_year rule followed by a only_mont
rule, while I'd like to obtain two day_month_and_year rules! I don't think I
can modify lexical scanner (controlling in the second number may stand for a
year or a day) because I'd want to specify yeras even with only the last two
digits. I think I could use associativity and precedence (maybe directly
applied to rules), but I can't figure out how to do it.
Any suggestions?
