Need Differentiation of Normal People and Character Profiles

I'm a perfectionist and Iove editing but an issue that has been largely ignored by people in the character profile box and lead to some of my edits being rejected is that we don't have something to show birthdays of various comic book characters without the year because most are simply ageless. Can somebody have this done so I can help fill out some of our beloved character's B-days

From a public source, a website called the 1997 DC calendar, it closed down sometime ago but I still have the details etched into my head.

@Allie_Ho: The ability to add incomplete dates is extremely unlikely.
