Six readers need a 90-minute evening for their August book-club meeting. Suggestions are scattered across chat and “Tuesday works” does not say whether every Tuesday time works. The organiser creates three exact candidates in Europe/Belgrade.

Known constraints keep the poll small

The library closes at 21:00 and the discussion needs 90 minutes. The organiser removes starts that cannot finish in time and proposes Tuesday 19:00, Wednesday 18:30, and Thursday 19:00.

Every candidate is an exact commitment

The meeting title is “August book club,” the location is the city library, and every candidate has a 90-minute duration. Participants answer all three dates instead of choosing only a favourite.

The invitation includes a deadline

The organiser tests the participant link, then posts: “Please answer every date by Sunday evening and save your private receipt if your plans change.” The management link stays in private notes.

The best match becomes one confirmed time

Tuesday receives five Available and one If needed; the other candidates each have at least one Unavailable. The organiser confirms Tuesday 19:00 and posts the exact time zone in the group chat.
