The first week is the first week with 4 or more days in January. Don't know why the first example returns 0.. However it seems to me that date('W') just takes the first of January as the starting day for the week-count. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19470&edit=1
