i use this to get a unix timestamp from a weeknumber and a year:
function weektoday($week,$year){
$day = strtotime($year."-01-01");
$dayofweek = date("w",$day);
if($dayofweek != 5 && $dayofweek != 6 && $dayofweek != 0){
while(1 != date("w",$day)){
$day = mktime(0,0,0,date("m", $day),date("d", $day)-1,date("Y",
$day));
}
} else{
while(1 != date("w",$day)){
$day = mktime(0,0,0,date("m", $day),date("d", $day)+1,date("Y",
$day));
}
}
$day = mktime(0,0,0,date("m", $day),date("d",
$day)+7*$week-7,date("Y", $day));
return $day;
}
monday is the first day of a week and a week with 4 days in the new year counts as week 1.
