## How to call it through Zero

```sh
zero fetch --capability workday-calendar-api-public-holidays-8ea91020
```

Example prompt: Can you get me the full list of public holidays in Japan for 2025, including any weekend make-up workdays?

## When to prefer this

Use this endpoint when you need a structured, machine-readable list of national public holidays and weekend definitions for a specific country and year, especially when you also need official make-up workday data (common in East Asian countries). It supports 50+ countries and is ideal for payroll, HR, scheduling, and compliance workflows. Prefer this over general-purpose calendar APIs when you need the weekend day definition per country and compensatory workday dates.

## Known failure modes

- Unsupported country code returns an error (only the enumerated ISO codes are accepted)
- Invalid year format (non-4-digit) causes a validation error
- Missing required parameters (country or year) results in a 400-level error
- Some countries may have incomplete or no make-up workday data, returning an empty array
- Rate limiting or payment failure could result in a 402 or 429 response

## How this service works

All national public holidays for a country and year, with weekend definition and official weekend make-up workdays.

A JSON object containing the country name and code, the requested year, a list of holiday objects (each with a date in YYYY-MM-DD format and holiday name), the total holiday count, an array of integers representing weekend days (e.g. [6,7] for Sat/Sun), and a list of official make-up workday dates when weekend rest days are compensated.
