Why is this challenging? It's whichever of 23 to 29 November (inclusive) is a Friday. For something more challenging, try the 8 Bank Holidays in England: (1) First weekday (i.e. Monday to Friday) of the year. (2) Good Friday, using UK Statute Law definition of Easter. (3) Easter Monday, ditto. (4) First Monday in May. (5) Last Monday in May [*]. (6) Last Monday in August. (7) First weekday after 24th December. (8) Second weekday after 24th December. [*] Except, if memory serves, in one recent year when it was moved to the first Monday in June. -- Clive D.W.
