list_upcoming_dinners

Lists upcoming Siena friendship dinners in a city between two dates, and says which ones are open to book. Siena holds one dinner a week, on Thursday at 7:30pm London time, for small groups of strangers who want to make friends. A few holiday Thursdays have no dinner, and the list leaves them out. Booking for a Thursday opens on the Wednesday two weeks before and closes on the Tuesday before at 23:59. With no dates, the tool lists the next 4 Thursdays. It lists up to 12 weeks ahead.
