Birthdays Aren't Displayed on IMDB Search & Biography

Hi,

I realized the birthdays of people who have chosen to hide their year of birth (age) aren't displayed on IMDB searches, so is this also intentional? Normally speaking, the system should only hide the age not the day because it is displayed on the respective page (as it should), but not in the auto-created biography because it hides everything related to the birthdate data.

For example: The day is visible, but on the automatic biography only the place of birth is seen.
