Never rely on the default date format of your client (which obviously isn't DD-MON-YY, because otherwise you wouldn't have gotten this error message) but always explicitly use the to_day function to eliminate ambiguity.

select last_day(to_date('01-FEB-95','DD-MON-RR')) from dual

is the correct select.
