This is a very interesting puzzle.   I am almost sure now that Cheryl's birthday is June 18.  Why? ... well just because that is the only date listed for which: if Albert knew the Month and Bernard knew the day, would be unique.  What i don't know is how Albert and Bernard established that situation by what they said to each other.
