[Evolution] Adding Public Holidays To Evolution?

[vincent <bullet ballmail co za>]

Hi Folks,

I've just installed evolution on lubuntu 14.04, after using TB for many
years and cannot find any recent advice, either on the forums or google
as to a workable method of adding public holidays. The most recent posts
appear to be 2005. Can evolution in fact do this, as is possible in TB?
Any help would be really appreciated.
