A dental clinic booking page: pick a service with real prices, pick a doctor by working days, pick a genuinely free time slot, get a booking code — at 11pm, when the clinic is closed but the booking engine never is.
The problem
Most small clinic sites offer only a phone number. Bookings have to happen during opening hours, while 35–45% of people actually decide to book outside them — evenings, weekends, commutes.
The solution
- Free slots computed per doctor and working-day calendar; taken slots are struck through — no double-booking theater
- After-hours bookings still HOLD the slot, with an honest banner: "we'll call to confirm after 8:00 tomorrow" — plus a "✦ earliest tomorrow morning" shortcut
- Booking code, "My bookings" view, one-tap cancel; Vietnamese phone-format validation while typing
Result
A complete book → confirm → cancel flow with real scheduling logic, demoable without a server. Clinics see themselves in it immediately.
