Answer 1

for all mondays of a year:

$date = '2016-01-01';
$y = date('Y', strtotime("$date"));
$x = $y;
while(1){
    $date = date('Y-m-d', strtotime("next Monday $date"));
    $y = date('Y', strtotime("$date")); 
    if($x != $y) break;
        echo $date."<br/>"; 
}

Answer 2

suppose you save month number in variable $month:

$firstDayOfmonth = mktime (0, 0, 0, $month, 1, date("Y"));
$threeweeksLater = strtotime(date("Y-m-d", strtotime($firstDayOfmonth)) . " +3 week");

now suppose you have year number in variable $year and week number in $week:

$firstDayOfEveryWeek = mktime (0, 0, 0, $month, ($week-1)*7, $year);
$threeweeksLater = strtotime(date("Y-m-d", strtotime($firstDayOfEveryWeek)) . " +3 days");
