- `{year}` _(optional)_ - If not set the current year is used
- `{month}` _(optional)_ - If specified list is filtered for given month
- `{day}` _(optional)_ - If specified list is filtered for given day
Examples:
- [`/us`](/us) - Federal holidays for the United States for the current year
- [`/de/2017`](/de/2017) - National holidays in Germany for 2017
- [`/de-by/2017`](/de-by/2017) - Holidays for Bavaria for 2017 (Uses [ISO 3166-2:DE](https://en.wikipedia.org/wiki/ISO_3166-2:DE) codes)
