FAQ

I am running into rate limits when calling the API - can you fix this?

As the API is heavily abused, aggressive rate limiting is in place. If you need higher rate limits, you need to self-host it.

Some dates are wrong - can you fix them?

The source ics files are here: https://github.com/paulbrejla/ferien-api-data. To change a holiday date, open the ics file for the state and year and find the holiday entry. Change the entry and create a pull request against main.

Dates are missing - can you add them?

The source ics files are here: https://github.com/paulbrejla/ferien-api-data. To add a holidays for a given state and year, provide an ics file and create a PR against main.
