From: agnermadsen@hotmail.com Operating system: windows 2000 PHP version: 4.2.1 PHP Bug Type: *Calendar problems Bug description: Wrong week number Wrong weeknumber is reportet for year=2001, month=12, day 31. The date function reports that is week number 53, but it is really week number 1. I fear that there are more bugs related to this problem. **** script start **** $date1=mktime(0,0,0,1,1,2002); $dag=date("w",$date1); if ($dag<=4) { echo $date1." is week 1"; $date2=mktime(0,0,0,1,1-$dag+1,2002); echo "<br>"; echo date ("Ymd-W", $date2); echo "<br>"; echo date ("Ymd-W", $date1); echo "<br>"; } **** script end **** **** output start **** 1009839600 is week 1 20011231-53 20020101-1 **** output end **** -- Edit bug report at http://bugs.php.net/?id=20363&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=20363&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=20363&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=20363&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=20363&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=20363&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=20363&r=support Expected behavior: http://bugs.php.net/fix.php?id=20363&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=20363&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=20363&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=20363&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=20363&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=20363&r=dst IIS Stability: http://bugs.php.net/fix.php?id=20363&r=isapi
