# gov.uk bank holidays JSON

## Probe

```
curl -s "https://www.gov.uk/bank-holidays.json"
curl -sI "https://www.gov.uk/bank-holidays.json"
curl -s "https://www.gov.uk/bank-holidays/scotland.json"
curl -s "https://www.gov.uk/bank-holidays/wales.json"
```

## Observed

- The root feed returns exactly three top-level keys —
  `england-and-wales`, `scotland`, `northern-ireland` — each `{"division": ..., "events": [...]}`.
  There is **no region for Wales alone**: Welsh bank holidays are identical to England's
  and only served under the combined `england-and-wales` key.
- `GET /bank-holidays/wales.json` → `HTTP 404` (standard GOV.UK HTML "Page not found"
  page, not JSON) — there is no per-nation endpoint beyond the three divisions above;
  only `/bank-holidays/scotland.json`, `/bank-holidays/england-and-wales.json`, and
  `/bank-holidays/northern-ireland.json` resolve.
- The full feed is one static JSON document: no query parameters are accepted for date
  filtering, year selection, or future-only/past-only slicing — a client wanting "next
  bank holiday" must fetch the whole array (83 events for england-and-wales) and filter
  client-side.
- Date coverage observed: earliest event `2019-01-01`, latest `2028-12-26` — a fixed
  ~10-year rolling window, not "all known holidays" and not "only upcoming".
- Each event: `{"title", "date" (YYYY-MM-DD), "notes" (often empty string, never
  absent), "bunting" (bool)}` — `notes` is empty-string-vs-absent, not null-vs-absent.
- Response headers: `content-type: application/json; charset=utf-8`,
  `cache-control: max-age=3600, public` — cacheable for an hour, no ETag/Last-Modified
  observed in this response.

## Why it matters

A client built against "the 4 nations of the UK" will reach for a Welsh-specific
resource that doesn't exist (and get an HTML 404, not a JSON one, continuing this
corpus's gov.uk pattern), and any client expecting server-side date filtering will
instead need to pull and filter the entire fixed-window document itself.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
