No, by default the events are from the country in system settings ->
locale Country/Region and Language -> Country.  So if you set Germany
there, you will see German holidays.

If you want to change it to your country, just change your country in
the locale (you have to restart plasma for the changes to take
effect).  If you want something other than your locale country,
right-click on the clock -> Digital Clock Settings -> Calender.  There
you can enable or disable as many holidays as you want.

There is already a holidays API, and people already can and do submit
holidays for different countries to KDE.

Korganizer can already use the API.  Go to Settings -> Configure
Korganizer -> Time and Date -> Regional -> Use Holiday Region.  It
doesn't appear to use your country by default, though.
