Wednesday

Wednesday was a day of the week. Clara Oswald would travel with the Eleventh Doctor on Wednesdays; when Clara told him she'd see him next Wednesday, he replied that it might very well be "last Wednesday" instead. (TV: Nightmare in Silver)

When the Tenth Doctor took her to New Earth but accidentally landed in the undercity, Martha Jones exclaimed that it looked more like her Earth on a Wednesday afternoon than an alien planet. (TV: Gridlock)

The Nineteenth Wednesday of the Year was a tradition celebrated by academics on the Braxiatel Collection. (PROSE: Fluid Prejudice)

Beginning in the 1980s, the Wednesday Girls — Jackie Tyler, Odessa Smith, Sarah, Suzie and Bev — met every Wednesday night for wine and chips. (PROSE: Rose)

Sylvia Noble had her own "Wednesday girls", too, including herself and Suzette Chambers. (TV: Partners in Crime)

Ace thought that Kirith looked like a wet Wednesday in Margate. (PROSE: Timewyrm: Apocalypse)
