ID: 18266 Updated by: srabol@mail.tele.dk Reported By: srabol@mail.tele.dk Status: Bogus Bug Type: Date/time related Operating System: W2K PHP Version: 4.2.1 New Comment: Hi Thanks for the quick answer. Would you be so kind and point me to the definition of the ISO date/time specification. print date("d-m-Y",mktime(0,0,0,12,30,2002)) . " Week : " . date("W",mktime(0,0,0,12,30,2002)) . "<br>"; also state that the week is 53. I've just looked in 2 different 'paper' calanders and both of them says that Dec. 30 2002 and Dec. 31 2002 is week 1 OFF-TOPIC, sorry My problem is that I need to know when a specific week in a year starts and ends. Previous Comments: ------------------------------------------------------------------------ [2002-07-10 16:54:01] rasmus@php.net According to the ISO date/time standards, Dec.31 2002 is indeed in week 53, so the output is correct. ------------------------------------------------------------------------ [2002-07-10 16:46:19] srabol@mail.tele.dk print date("d-m-Y",mktime(0,0,0,12,31,2002)) . " Week : " . date("W",mktime(0,0,0,12,31,2002)) . "<br>"; The above line give this result: 31-12-2002 Week : 53 And according to my calendar there is no week 53 in year 2002 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18266&edit=1
