I found one

BBC Site list Bobby Beale as being born in episode 24 July 2003, but on his  list his Date of Birth as 22 July 2003.

Wheather they go by when it was filmed or just choose a date near to that time who knows.

It might even just be a continuity error or maybe they have a file with all the character births in it,
