Theory:Doctor Who television discontinuity and plot holes/The Doctor, the Widow and the Wardrobe


 * The Doctor arrived at Amy's house in 2013, two years late, yet managed to get the date exactly correct. If the year was not right, why would the date be?
 * Why shouldn't it be? Maybe the date is easier to get right than the year, maybe he hit a wrong button, maybe the TARDIS just felt like taking him to Christmas, or maybe he remembered that Amy and Rory were somewhere in the early 21st century, but he couldn't remember the exact year.
