Yes, there is an ISO standard. I don't recall the number. As far as I
know, week numbers aren't much used in the US, for instance. At least
in the Nordic countries it is very common to refer to week numbers, as
in "How about week 24 for the next meeting?".

It is interesting to note that ANSI C and POSIX strftime(3) uses the
wrong week numbering algorithm, at least according to its manual page
in HP-UX, which says:

           %W        week number of the year (the first Monday as the first
                     day of week 1) as a decimal number [00,53]

while the standard says that the week which contains the first
Thursday is week one. Week one could thus start in the previous year,
as it did this year, 1992. Week 1 began on Monday, 1991-12-30 (this is
the ISO standard (human-readable) date format, btw), and ended on
Sunday, 1992-01-05.
