December

Trends
December contained the holiday of Christmas (TV: Children in Need Special) and the phenomenon known as the winter solstice, the moment where daylight would reach its lowest amount and increase afterwards. As a consequence, it contained the exact mid-point of winter and therefore the instant when people were, in the words of Kazran Sardick and the Eleventh Doctor, "halfway out of the dark". (TV: A Christmas Carol) During the early 21st century, the time around Christmas was often subject to alien invasions. (TV: The Christmas Invasion, The Runaway Bride et al.)

December also contained "Krampus nacht" on December 5th. This day was once attended by the Eighth Doctor, Liv and Helen. (AUDIO: Better Watch Out, Fairytale of Salzburg)

As the two previous Christmases had been disrupted by the arrival of alien spacecraft over London, most residents of the city had left for the season so nothing devastating would ruin their holiday. Those choosing to remain in the city included Queen Elizabeth II and Wilfred Mott. A series of meteorites were deliberately allowed to collide with the de-shielded Titanic, causing the ship and its nuclear storm drive to hurtle towards Earth.
