well, I learned some php doing that. %)
I wrote a couple programs that will do conversion back and forth between the Gregorian calendar (the one I live on and think in) and the Marraketh calendar (Marraketh is my fictional alt.universe, the place Katze comes from).
So yeah, even though it may not make much sense to anybody, you can find them at:
From the Marraketh calendar to the Gregorian calendar
From the Gregorian calendar to the Marraketh calendar
Now I have to find *another* project. ;)
