Hi,
I made a few Ical calendars that you can use in Epim if you like. This is mostly for Swedish people.
Swedish Flagdays (2024) - https://github.com/HomeOffline/Flaggdagar
Free (non work) days in Sweden (2024) - https://github.com/HomeOffline/Rodadagar
Name day in Sweden (2024, but could be repeated for ever i think) - https://github.com/HomeOffline/Namnsdagar
Special days (2024) in Sweden sane version (2024) - https://github.com/HomeOffline/Temadagar
Special days (2024) in Sweden insane version (2024) - https://github.com/HomeOffline/TemadagarCrazy
Nationaldays for most of the planet - https://github.com/HomeOffline/Nationaldagar
Let me know if there are any errors.
Fun fact: I used EPIM to create the events and then exported them to ICAL.
