Just after Gussie finishes most of his brandy and heads out of the pub to steal back the dog, there is a poster on the wall advertising the Totleigh in the Wold Annual Concert. It says it shall be held on Saturday 20 August, but since this year is 1931, which can be ascertained by a number of hints over time, and the General Election that comes up later (which happened in 1931, with not another until 1935), then 20 August was a Thursday. 20 August was a Saturday in 1932.
