Name Description

Name	Description
get_public_holidaysA	Full list of official public holidays for a country in a given year. Use for "what are the holidays in Germany in 2026", planning around a country's holiday calendar, or any "list the holidays for X" question. `country_code` is a 2-letter ISO code (US, GB, DE, FR, JP, ...) -- roughly 100 countries are covered, not every country worldwide. Returns each holiday's date, local name, English name, and type (e.g. Public, Bank, Observance).
is_public_holidayA	Checks whether one specific date is a public holiday in a country, and names it if so. Use for "is Dec 25 2026 a holiday in the US", "is the office closed on this date", or any single-date holiday check -- prefer this over `get_public_holidays` when the question is about just one day. `country_code` is a 2-letter ISO code; `date` is YYYY-MM-DD. Returns whether it's a holiday and, if so, its name.
