March
(Note: Dating and other information is suggested by the Telos novella, "Time and Relative," although it seems to contradict material in "An Unearthly Child" and "Remembrance of the Daleks" suggesting that the TARDIS  arrives in May. See Dating disputes.)
 * Late March - The TARDIS materializes in the junkyard at 76 Totter's Lane, owned by I.M. Foreman, in the Shoreditch area of London, it's navigational systems and chameleon circuit damaged by radiation from the Hand of Omega. While the Doctor attempts repairs and works out a plan for safely disposing of the Hand on Earth, Susan, against his wishes, registers at the nearby Coal Hill School. Britain, meanwhile, is in the grip of an unusual cold wave.
