You can either use the method described at
http://www.slipstick.com/contacts/calcage.htm or you can do what I do -- add
the year of birth in square brackets at the end of the subject of the
appointment. For example, "Joe Schmoe's Birthday [1956]". I use square
brackets instead of parentheses because when I use parens, Outlook thinks I
am adding a location to the appointment and it puts the year in the Location
field for me.
