Adding birthdays to the calendar that updates age

[Goonie]

Hello,

I'm running a Movie forum and I want to add actors birthdays to the calendar BUT I want the birthdays to display the age and update every year... like it does on IMDb.

I was considering creating a usergroup for actors and then adding each actor as a new user to that usergroup and then their birthday displays on the forum and the actors age would update itself every year, but this is abit of a mission and I don't want hundreds of members who are not real members. Does that make sense?

I realise this probably requires some coding but I'm rubbish with this stuff so would really appreciate some help.

Thank you.
