1989 would be correct. In bells of Saint john, she was apparently 24 given it being the last age in Her book. We know bells of Saint John took place in then current day 2013. So if she was 24 in 2013, she would've been born in 1989 - and its Moffat. Chances are he did that deliberately as 1989 is a well known year (not for the best of reasons) in the whoniverse
