Implied Slot availability — a worked example from one real club-day

Sample feeds supporting openactive/open-booking-api#242.

Generated from one real club's actual bookings on Sunday 27 September 2026, taken from ClubSpark production. The club identity and all URLs are anonymised; the court count, opening window, 30-minute start interval, price structure and the complete booking pattern for the day are exactly as recorded. No customer data of any kind appears in a Slots feed, so none appears here.

The configuration shown here: a single duration

Each court publishes one beta:TemplateSlot, whose duration equals its repeatFrequency. Implied Slots therefore tile the day without overlapping, and a booking longer than one Slot is composed from consecutive Slots — one OrderItem each, in a single Order.

Mathematical solution to https://cdn.cs50.net/2020/x/events/puzzles/puzzles.pdf -> Putting it all together

First, we encode tiles into binary in low-byte order, assuming an 8-bit row-size.

For example:

 J
UN
H
