Sorry for your trouble. Can you delete this failed bug report? ;) Tnx ------------------------------------------------------------------------ [2013-09-21 18:48:10] glavic at gmail dot com I made a copy/paste typo before, but that doesn't matter now because you said that 'Y' returns the year of the date, which is totally correct, where was my head... I understand what you are saying; I agree that Dec 30 and 31 fall in week 1; but year 2014, not 2013. Maybe I should rephrase my question: how do I get correct week year from "echo (new DateTime('2013-12-30'))->format('W ????');" ? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
