It turned out that there is no bug. It is just %W week numbering is not the same with ISO week numbering accepted by `org-read-date'. You need to use %V to get the identical numbering. Otherwise, the numbering will differ depending on when the first week of the year starts. -- Ihor Radchenko // yantar92, Org mode maintainer, Learn more about Org mode at <https://orgmode.org/>.
