Simple editor for holiday files (currently only with a backend for the plan-like holiday files that we currently use in libkholidays). It's written in ruby using the korundum bindings for KDE 3.5 (KDE 4.0 doesn't have any bindings yet).

It mostly works, the only part that's missing is that when loading a file, the date part is not loaded (name, type, offsets, length, even conditional shifts are loaded, but the date itself is not). So, don't use it an production data yet!
