Where is the birthday template??

[Littlebit]

I have an issue like this...
I would just like to make the age not visible on the forum home. I located the calendar birthday templates and put <!-- --> around the $age ... so it works successfully in the calendar. The forumhome still shows the age though. So I found the $age= line in functions.php, but before I alter that, I want to make sure there isn't a template I over looked or an easier way to get the age not visible on forum home. Could someone give me some advice? Thanks
