Next public holiday

HTML

Embed code

Copy this iframe into your page. Adjust width and height to suit your layout.

<iframe src="https://kalender.wiki/widgets/next-holiday?country=DE&lang=en" title="Next public holiday" width="100%" height="176" loading="lazy"></iframe>

JSON API

The API requires no sign-in and returns the date, name, scope, remaining days and data status. CORS is enabled for browser-side GET requests.

https://kalender.wiki/api/v1/next-holiday?country=DE&lang=en

Parameters: country (required ISO 2 code), lang (de/en), from (YYYY-MM-DD, optional) and region (an exact available subdivision code, optional). dataStatus=unavailable explicitly means that a complete public-holiday dataset is not available.

Usage notes

The widget may be embedded free of charge as long as the visible link to kalender.wiki remains. Data may change after official announcements; applications should cache responses and avoid repeated requests on every page view.
