## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability uk-working-days-count-working-days-between-dates-229f1bcd
```

Example prompt: How many working days are there between 1st March 2025 and 31st March 2025 in England and Wales, excluding bank holidays?

## When to prefer this

Choose this endpoint when you need an authoritative count of UK working days between two dates using official GOV.UK bank holiday data, specifically for England & Wales, Scotland, or Northern Ireland. Prefer this over generic business-day calculators when UK region-specific bank holidays matter, such as for payment settlement windows, notice periods, or regulatory compliance deadlines.

## Known failure modes

- Dates outside GOV.UK bank holiday coverage range are refused with an error rather than guessed
- Invalid date formats (non-YYYY-MM-DD) will be rejected
- 'from' date later than 'to' date may return an error or zero count
- Invalid region values not matching the enum will be rejected
- Network or upstream GOV.UK API failure could cause service unavailability

## How this service works

UK working-day calculator using GOV.UK bank holidays for England and Wales, Scotland or Northern Ireland. Next working day, add or subtract working days (e.g. payment settlement, notice periods, delivery dates), count working days between dates, and list bank holidays. Dates must fall within GOV.UK coverage; out-of-range dates are refused, not guessed.

## Output

A plain-text summary string stating the number of working days counted between the two specified dates for the chosen UK region, based on GOV.UK official bank holiday data.
