Cuba Gooding, Jr.

Cuba Gooding, Jr. was a human with whom the Jackie Tyler of a parallel universe shared her birthday, 1st February. Gooding, Jr was born in 1968, and Jackie's autobiography claimed she was born on the same day he was. Jackie was actually born a year earlier. (DW: Rise of the Cybermen)

Gooding Jr. was actually born on the 2nd January in the real world. It's not certain if the discrepency is because Rise of the Cybermen is set in a parallel world or because Jackie (or the production) crew forgot that the style 02/01/19XX would be 2nd January in the UK but 1st February in the USA .
