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 :-)

Of course, some people pick "whatever Excel does". Don't do that ;)
