Looking for calendar script

I’m looking for a calendar script to create something like https://www.kalender-365.be/kalender-2020.html. Basically I want to create a website (with calendar view) that displays all the holidays for each country in Europe.
Multi-language support would be a plus as each country has a different language.

Does anyone have this kind of script or template for sale?

You don’t really need a script. You can use WordPress blog and use the calendar system as a start.
Then you can rewrite few codes and show the only post if the “date” is “today” condition ( with this extension, for example )
