for ease of implementation I'd even suggest three separate properties:
- yearOfBirth
- monthOfBirth
- dayOfBirth

those would allow to:
- make your age available, but not your birthday
- publish your bday's day and month, but not your age
- easily select people's birthdays from a triplebase for
  a given day/month combination

another nice use case:
- find people at your age (yearOfBirth) that share the same
  foaf:schoolHomepage with you

I'd actually like to see handy general year/month/day
properties. e.g. for finding "people I met last year"
via co-depictions for a given year etc.
