btw, did you consider replacing calendar w/ the one from openbsd or 
freebsd? they both seem to be more feature rich...

i.e. I can use things like

Easter=Ostern
Easter+1 	Ostermontag
...
12/Sun+2	3. Advent
...
10/SunLast	Anfang der Winterzeit
usw.

there, so I don't have to care for the actual dates, free/openbsd's 
calendar is doing this for me, with netbsd's calendar, I have to correct 
the dates every year :-(

comments?
