I was looking for a way to convert a week- and daynumber to a UNIX timestamp. I found Robert
Christaanse code below but I found it a bit wordy so I rewrote it to this function:
<?PHP
function datefromweeknr($year, $week, $day)
{
$jan04 = mktime (0,0,0,01,4, $year); // jan 04 always in week 1
$firstday = date("w", $jan04); // fetch day of week of jan 04
$offset = ($week-2) * 7 - $firstday + $day; //calc number of days difference from jan 04
return strtotime('+' .$offset .' days', $jan04);
}
?>
Hope it helps out ;)
