Public holidays for 200+ countries and their regions, plus workday checks, workday counts and deadline math (N working days after a date), computed in code instead of by the model.

## Good to know before installing

Sends HTTPS GET requests to date.nager.at (Nager.Date, free, no key) carrying only a country code and a year; no redirects, 10 s timeout, responses cached in memory only. No credentials, no files written, no shell commands, no hooks, no background processes, no telemetry.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install public-holidays
```

2. Said no? Turn it on later:

```bash
hermes plugins enable public-holidays
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
