That's just about it. Considering she was literally made out of clay, she wasn't "technically" born, so... there's that. However, the amazons may celebrate the day she came to them. Since the current continuity Diana is seen as the daughter of Zeus,she must have been born in some way. Outside of that, Diana has shown a willingness to participate in and learn about common human customs, so a Birthday of her own would probably be one of them.
So yeah...does Diana have an official birth day?
Does she celebrate it, or has their been any instance seen of her celebrating it, in the old or new continuities?
And if so...when is it?
