ID: 65694 Updated by: der...@php.net Reported by: philippe dot alcaina at hotmail dot fr Summary: error calendar in year 2016, with function mktime() -Status: Open +Status: Not a bug Type: Feature/Change Request Package: Date/time related Operating System: windows linux PHP Version: 5.5.3 Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This seems to work just fine. PHP uses the ISO8601 calendar which indeed has a week "2015-53" for the period Mon Dec 28, 2015 to Sun Jan 3, 2016. Please see http://en.wikipedia.org/wiki/ISO_week_date for more information.

For an internet tool I need to get a list of weeks after having selected one year and one month. By testing I found a BUG in the year 2016. PHP gives me: 1 January 2016 the number of week: 53 (instead of 1) January 31, 2016 the number of week: 4 (instead of 5) then the error shifts in other months. The system works correctly in 2013, 2014, 2015. Test script: --------------- I provide you sample of the code that allows me to build this list of weeks, I particularly use mktime () // timestamp of first day of month $time = mktime(0,0,0,$mois_select,1,$annee_select); // number of days of month $nbrJoursMois = intval(date('t',$time)); // the number of the first week $numSemaineDebutMois = intval(date('W', $time)); // timestamp of end month $timeFinMois = mktime(0,0,0,$mois_select,$nbrJoursMois,$annee_select); // the number of the last week $numSemaineFinMois = intval(date('W', $timeFinMois)); /**** Display results ****/ $annee_select = 2016 $mois_select = 1 $time = 1451602800 $nbrJoursMois = 31 $numSemaineDebutMois = 53 (Error) $timeFinMois = 1454194800 $numSemaineFinMoisnum = 4 (Error) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65694&edit=1
