Sportferien and other holidays missing for Canton of Zurich

[Nukles]

Typical Dates: February 9, 2026 – February 20, 2026 are the Spotferien in the Canton of Zurich, Switzerland, but they are not detected e.g. by the following API call.

https://openholidaysapi.org/SchoolHolidays?countryIsoCode=CH&subdivisionCode=CH-ZH&validFrom=2026-01-01&validTo=2026-12-22

See the home page of the canton of Zurich.

Other holidays from the ZH canton seem to be missing:

Sechseläuten (Spring Festival)
This is a specific local holiday for the City of Zurich.
Date: Monday, April 20, 2026.

Knabenschiessen
A traditional Zurich holiday in September.
Date: Monday, September 14, 2026.

Is it possible to incorporate them in the API? Thank you, that would be great!

Update - I think it's because in your reference PDF for ZH is written "sportferien variiert", which means that it varyies...

however they seem to be fixed if taken from the home page of the Canton.

Hi, they are fixed for the city of Zurich but not for the canton of Zurich.

About Sechseläuten (Spring Festival) + Knabenschiessen: It's there, but its part of the public holidays API endpoint.

Example:

Many thanks! That clarifies.

As most of the districts in the Canton of Zurich adopt the City of Zurich Sportferien, is it possible to use the City of Zurich as the reference for the API rather than no one at all?

[fstueber]

Yes, that makes sense. Will update.

Thank you!

@fstueber I hope this message finds you well! I checked today but I am still unable to see the forthcoming Sportsferien when polling the Canton of Zurich. I had suggested that as most of the districts in the Canton of Zurich adopt the City of Zurich Sportferien, maybe would make sense to use the City of Zurich as the reference for the API rather than no one at all.

Did you manage to update the API or will this feature not be implemented? Thank you and have a great rest of the day!
