Saturday

Saturday was a day of the week. The Doctor, in his fourth, (PROSE: Shada) tenth (TV: The Stolen Earth) and eleventh incarnations, (TV: The Impossible Astronaut) declared that he liked Saturdays. The Eleventh Doctor called it a "big temporal tipping point, when everything is possible." (TV: The Impossible Astronaut)

At least some schools, such as Coal Hill Secondary School, were closed on Saturdays. On every such afternoon, Susan Foreman would use the time to babysit Malcolm until the six-year-old's Aunt Junie arrived on 4 April 1963. (PROSE: Time and Relative)

Lucie Miller recounted how she didn't feel the cold much when she was out clubbing in Blackpool on a November Saturday night. (AUDIO: Blood of the Daleks)
