## 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 agenttools-business-days-calculator-5dc2a89b
```

Example prompt: How many business days are there between March 3, 2025 and April 18, 2025, excluding US public holidays?

## When to prefer this

Use this endpoint when you need a precise count of working days between two dates, especially when you need to exclude public holidays for a specific country. It is ideal for deadline calculations, SLA tracking, invoice payment terms, HR notice periods, and project scheduling. Prefer this over manual date arithmetic whenever country-specific holiday data matters.

## Known failure modes

- Missing start or end date parameter returns a 400 error
- Invalid date format (non-ISO 8601) causes a parse error
- Unsupported or invalid country code returns an error or falls back to no holiday exclusion
- End date before start date may return zero or a negative count
- Network errors to Nager.Date public holiday API could cause holiday lookup to fail

## How this service works

Count business days (Mon–Fri) between two dates, with weekend and holiday breakdown. Provide a country code and real public holidays (via Nager.Date) are excluded too. Use this when an agent needs to working days between dates, optionally minus public holidays.

## Output

Returns a structured object containing the total number of business (working) days between the two dates, the number of weekend days excluded, the number of public holidays excluded (if a country code was provided), and a list of the specific public holidays that fell within the range.
