Erik Cederstrand added the comment: I would like to point out that http://bugs.python.org/issue12006 provides a solution (including patches) based on %G%, V and %u directives for use in strptime()/strftime(). These directives are defined in (FreeBSD) libc, and PHP has them, too. I think the

Esben Agerbæk Black added the comment: I believe that it is a good solution to have, for lack of a better term; bi-directional features so in my opinion .isocalendar() merits having a constructor that takes an ISO format. Sadly no :-( I looked it over once more and it seems there is an error w
