Oh right, the German version knows how it's done in the States but the English
one doesn't. Please excuse me if I don't really accept this as fact,
particularly as the page itself claims that the information is not verifiable
and needs references.

Unfortunately you didn't tell us which locale you ran it under, but anyway,
let's have a look:
$ export LC_ALL=de_DE.UTF8; ncal -bw 1 2005
Januar 2005
w| Mo Di Mi Do Fr Sa So
53| 1 2
1| 3 4 5 6 7 8 9
2| 10 11 12 13 14 15 16
3| 17 18 19 20 21 22 23
4| 24 25 26 27 28 29 30
5| 31
Except for formatting changes this is exactly your case 1, right?
As for the second, see above. Unless proven wrong I stick with what the locale
gives me.
