There's no such thing as "the week number in emacs". Or... there are
at least three.
Cribbed from the docs (C-h i format-time-string):
"%U is the week number starting on Sunday, %W starting on Monday,
%V according to ISO 8601."
The thing is there are many meaningful ways to define such a thing
as a "week number", and several of them are in current use. See,
e.g. [1] for even more fun :-)
Once you know what kind of results you want, the rest tends to be
easier.
Of course, some people pick "whatever Excel does". Don't do that ;)
Cheers
