> In his book Disgusting Bliss: The Brass Eye of Chris Morris, Lucian Randall says that the pilot of The Day Today was “completed in January 1993”. I can independently verify this; the VT clock for that pilot is dated 29th January 1993. So the pilot for The Day Today was shot in either December 1992 or January 1993. Which gives us a rough date for this particular limbo incarnation of Partridge.

Where does "December 1992" come from in this sentence? Is there a specific reason why it couldn't be October or November 1992?

(I mean, maybe it's just common sense that a programme wouldn't take that long to shoot, but I feel like the author is more confident than that given the rigorousness displayed throughout the rest of the article.)
