French Public Holidays by Year and Zone

Use this endpoint when you need an authoritative, zone-aware list of French public holidays for a specific year — especially when handling Alsace-Moselle or French overseas territories (DOM-TOM) that have different public holiday rules than metropolitan France. Prefer this over generic calendar APIs that may not account for French regional variations.

• Invalid or unsupported zone name returns an error or empty result

• Year outside supported range may return empty or error
• Misspelled zone name (e.g. 'alsace' instead of 'alsace-moselle') may return no results
• Network or payment failure returns no data
