I think we got off on the wrong foot on this discussion. I'm not arguing
for or against anything, just trying to clarify what we have and will
have in the future. afaik nothing existing or proposed is at odds with
any national or international standard.

In particular, "week of year" is defined in ISO-8601, and I'm not
remembering any other standard or convention which would specify an
incompatible definition of this concept. The "year" associated with
"week of year" is not guaranteed to coincide with the common-usage
"calendar year", but that is specified in the standard.
