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)

By the end of their travels together, the Twelfth Doctor, Bill Potts and Nardole regularly took to adventuring in the TARDIS, and answering distress calls, as a "usual Saturday". (TV: World Enough and Time)

Behind the scenes

Until 2018, Doctor Who had aired regularly on Saturdays on BBC One, since the 2005 revival. The series originally premiered on Saturday as well, and regularly aired on that day of the week from the start.

Beginning with series 11, Doctor Who airings moved to Sundays instead.
