[kronolith] Base for German holidays

[Manuel Schwab]

Hello list,

I wonder what the base is for the German holidays.

I acticated the option to show the German holidays.
Now I see some strange holidays I never heard before.
Examples:
01.09.2009: Anti-War Day
12.09.2009: Day of German language
14.09.2009: Celebration of raising the Cross
.
.
.

Is this the normal behaviour?

Thanks.

Manuel
