Saturday

Saturday was a day of the week. The Doctor, in both his fourth and tenth incarnations, declared that he liked Saturdays. (PROSE: Shada, TV: The Stolen Earth)

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)
