Requires: phpFox v3.1.0 or higher

To control how the date of birth is displayed on a users profile by default (when they haven't selected a setting yet) you can log into your AdminCP and go to:
Settings >> Manage Settings >> User

Look for the setting Default Birthday Privacy Setting.

Here is a key of what the values stand for...
full_birthday = Show full birthday
month_day = Show month & day
show_age = Only show the users age
hide = Hide users age/birthday
