Hi Mark,

I'm one of the maintainers of the KHolidays library which provides the holiday 
events throughout KDE, and sometimes contributor to the plasma clock/calendar.  

You can find some information about KHolidays at , in particular some details about 
plans for a new version of the file format and library that should be more 
flexible and portable and easier to contribute to.  Ideally the data files 
would be a cross-desktop effort.

You can also find some more details in the slides for a talk I gave at the 
last Desktop Summit.  Sadly no video survived :-) See

It could be an interesting GSoC project to try implement the new file format 
and library, but I'm not sure I can mentor it, I tried last year and made a 
hash of it, and I'm unlikely to have enough time this year either.

It does sound like there are some problems with your config, Holidays in the 
Plasma Clock do seem to work correctly for most people now.  Perhaps find and 
delete the config file for the clock?  Or try it in a new user to see if it is 
broken there?
