The dates and times of the two remaining Doctor Who specials have been announced.
The End of Time, Part One is on, as tradition demands, Christmas Day at 6pm.
The End of Time, Part Two, an extra-long 75 minute episode is on New Year’s Day at 6:40pm.
Times are for BBC One, but I’d expect them to be on the BBC HD channel at the same time. Check listings to confirm, etc.
 I think the traditional nature of the Doctor Who Christmas Special has been established
