I tried to find an explanation and only found a fellow seeker of the truth [0] that also couldn't find the answer [1]. He probably tried to search for it more than me.

I found the Apple source code for ncal [2], but no answers there. Also it is funny that Latin line has the month entered in octal (05).

Damn, you stole my chance to link to the xkcd comic. Randall does have an xkcd for everything.
