$MLK = date('Y-m-d', strtotime("january $curYir third monday")); //marthin luthor king day
$PD = date('Y-m-d', strtotime("february $curYir third monday")); //presidents day

$MDay = date('Y-m-d', strtotime("may $curYir first monday")); // memorial day
//("may $curYir last monday") will give you the last monday of may 1967
//much better to determine it by a loop
$eMDay = explode("-",$MDay);
$year = $eMDay[0];
$month = $eMDay[1];
$day = $eMDay[2];
while($day <= 31){
$day = $day + 7;

if($day > 31)
$day = $day - 7;
$MDay = $year.'-'.$month.'-'.$day;

You can leverage this function of php. strtotime
$currentYear = date("Y");
MLK Day -
echo date('Y-m-d', strtotime("third monday of january $currentYear"));
Presidents Day -
echo date('Y-m-d', strtotime("third monday/OD February $currentYear"));
Easter -
echo date('Y-m-d', strtotime("last sunday of march $currentYear"));
Memorial Day -
echo date('Y-m-d', strtotime("last monday of may $currentYear"));
