Bank holiday
From Tardis Wiki, the free Doctor Who reference
A bank holiday was a day of leisure, usually held on a Monday, observed at least in the United Kingdom. According to a story she once told Merry Gejelh, Clara Oswald once had a life-changing moment on a bank holiday spent in Blackpool. There, on a crowded beach, she got separated from her mother. Clara was afraid, but her mother's reassurances after the event allowed her to conquer the fear of getting lost. (TV: The Rings of Akhaten)
