Don’t let the title of this episode fool you. It’s not about the Doctor’s relationships with people who are considerably younger. Actually, it’s about the Doctor’s age. How good of a handle do we have on that aspect of the Doctor’s life? Is there any way to know for certain how long the Doctor has been traveling in the TARDIS? We’ll tackle these questions this month and apparent contradictions in our data.
Transcript
One thing I think we all can agree on is that the Doctor is supposed to be rather old. Sometimes onscreen he informs us how old he is, usually in round numbers, but on occasion specifically. Generally, we find that his age has increased over time, as we should expect, but it has not always been consistent in the way it is presented. Fortunately, for the most part, there have not been any major contradictions, either in the classic series or the modern. But between them, there is. In the classic series we see the Doctor age from about 400-something to about 900-something. In the new series he ages from 900-something to over 2,000. Seems about right. If we look a little closer, however, there is a glaring discrepancy. I suppose you could call it an overlap. In Time and the Rani, the 7th Doctor gives his age as 953, but later in Voyage of the Damned, the 10th Doctor says he is only 903.
What are we to make of this? Did the Doctor get 50 years younger between those two adventures? Well, it seems clear that Russell T. Davies neglected to research the subject thoroughly enough and thus made an error. But now that the productions have been made, we are stuck with it. The good news is that I think the bump can be smoothed out.
One solution that has been suggested is that the Doctor simply can’t remember how old he is. Yet, he is so specific when he says 903, 906, 907, 909, etc., during the modern series, and both the Rani and the Doctor agree that they are 953 years old in Time and the Rani. This really doesn’t seem to be a case of faulty memory.
A better solution, and I am not the first to suggest it, is that the Doctor sometimes gives his age in Earth years and other times in Gallifreyan years, and that those years are not equal to each other. There is evidence that he has done this.
For example, when he tells Victoria that he is “something like 450 years old” in The Tomb of the Cybermen, it seems clear that the Doctor is talking about his age in Earth years, for he is attempting to help Victoria to understand. He does some math in his head first, which shows he is making a conversion from a system of measurement that he is more familiar with to that of Earth.
Elsewhere it is clear that the Doctor is talking about his age in Gallifreyan years. In Time and the Rani, he punches in his age (which is the same as the Rani’s) 9-5-3 into a lock mechanism programmed by the Rani. She is not likely to have used Earth’s system of measuring time, so the number must have been Gallifreyan. This suggests that, at this time, he and she were both 953 Gallifreyan years old.
So now we need to ask ourselves, on which occasions is the Doctor using a Gallifreyan figure, and when is he speaking in Earth terms? I think we are justified in thinking that, when he is talking with Romana, another Time Lord, they are measuring by the calendar they are both familiar with: that of Gallifrey. This would suggest that in Seasons 13 to 17, when his age is consistently in the 700s, we are hearing his age in Gallifreyan years.
On the other hand, since the age of the Doctor in the modern series starts out in contradiction with that in Time and the Rani, we must conclude that the age he gives is in Earth years. In fact, since the Doctor’s age is consistent throughout the modern series, it is probably easiest and simplest to conclude that his age is always given in earth years. Conversely, with the exception of Tomb of the Cybermen,
