# DiveDay

> DiveDay is booking and operations software for dive shops. Every shop on DiveDay has a public schedule of departures (boat dives, shore dives, course sessions) that anyone can read and book without an account. DiveDay is not itself a dive operator: each shop sets its own departures, prices and requirements.

## A shop's public pages

- Schedule: https://dive.day/s/<shop-slug> — the shop's upcoming departures, reviews and courses, as HTML with schema.org JSON-LD (an ItemList of Events).
- Availability: https://dive.day/s/<shop-slug>/availability.json — the next 14 days of departures with a seat open, as JSON. Read this to find a departure. Absent (404) for a shop that has chosen not to be listed.
- Booking page: https://dive.day/s/<shop-slug>/trips/<trip-id> — one departure, and the form that books a seat on it. Bookings happen on this page and only here; the availability document is for finding a departure, not for booking one. Hand your reader this URL (it is each departure's booking_url).
- Courses: https://dive.day/s/<shop-slug>/courses — the shop's course catalog, each course on its own page beneath it.

## Reading availability.json

- departures[]: id, title, starts_at and ends_at (the shop's wall clock with its UTC offset, e.g. 2026-07-25T07:30:00-04:00), time_zone (IANA), sites (dive site names in dive order), price ({ amount, currency } as a decimal string in the currency's own places, or null when the shop has not priced it), certification (null when the departure asks nothing, otherwise minimum_level, required_specialties and requires_nitrox), seats_open, booking_url.
- certification.minimum_level is one of open_water, advanced_open_water, rescue (lowest to highest) or null; required_specialties are codes from deep, wreck, night, drysuit; requires_nitrox is a boolean. These are what the diver will be asked to show before boarding, not a suggestion.
- Only departures a visitor could book right now appear: a full boat, a private charter and a departure on a conditions hold are left out. Fields you do not recognise are safe to ignore.
- window.from and window.to bound the document; generated_at is when it was written. Seats change as people book, so treat seats_open as a snapshot and let the booking page have the last word.
