How do I list all the holidays for a specific country in 2024?

Simply ask the agent to `list_holidays` and provide the Country code (e.g., 'US' or 'BR') and the year '2024'. It will retrieve the full list from Calendarific.

Can I filter holidays by type, like only religious holidays?

Yes! Use the `list_holidays_by_type` tool and provide the country, year, and type (e.g., 'religious'). Your agent will return only the matching observances.

How do I see which countries are supported by Calendarific?

Use the `list_supported_countries` tool. It will retrieve the complete directory of over 230 countries currently available in the Calendarific API.
