## 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 public-holidays-and-workdays-nager-date-fa2fc9cf
```

Example prompt: Can you check if March 17, 2025 is a public holiday or weekend in Ireland (IE), and if so, what the next business day would be?

## When to prefer this

Choose this endpoint when you need authoritative public holiday data for 200+ countries with both local-language and English holiday names, regional subdivision support, and built-in next-business-day calculation. It is especially well-suited for deadline/SLA math, payroll scheduling, and delivery date logic where you need to skip both weekends and public holidays in a single API call. Prefer it over generic calendar APIs when you need compact JSON output and per-call micropayment pricing without a subscription.

## Known failure modes

- Unsupported country code returns an error or empty holiday list
- Invalid date format (not YYYY-MM-DD) causes a bad request response
- Year out of supported range (roughly 1976-2074) may return empty or error
- Regional subdivision code not recognized for the given country returns only nationwide holidays or an error
- Missing required 'land' parameter defaults to NO (Norway) which may be unintended

## How this service works

Public holidays and business-day check for Norway and 200+ other countries, from the open-source Nager.Date holiday database. Without dato: every public and bank holiday of a year with local and English name and whether it is nationwide or regional. With dato: whether that date is a holiday or weekend, plus the next business day. Use it for deadline and SLA maths, delivery and payroll scheduling, or opening-hours logic. Compact JSON.

## Output

For year-mode requests: a JSON object with the year, country code, source attribution, and an array of holiday entries each containing the date, local name, English name, and a flag indicating if it is nationwide or regional. For date-mode requests: a JSON object indicating whether the given date is a public holiday or weekend, plus the next business day (neste_virkedag) as a date string.
