Solution for moving holydays in Germany: returns an array of 'Y-m-d' formated strings including good friday, easter monday, ascencion, and pentecost monday. A new DateTime object for easter ist created for each day to enhance readability.

function beweglicheFeiertage( int $year ):array
{
    //Karfreitag - good friday
    $return = array();
    $easterDate = DateTime::createFromFormat('U', easter_date($year) );
    $easterDate->modify('- 1 days');
    $return[] = $easterDate->format('Y-m-d');
    //Ostermontag easter monday
    $easterDate = DateTime::createFromFormat('U', easter_date($year) );
    $easterDate->modify('+ 2 day');
    $return[] = $easterDate->format('Y-m-d');
    //Himmelfahrt ascencion
    $easterDate = DateTime::createFromFormat('U', easter_date($year) );
    $easterDate->modify('+ 40 days');//go to Ascencionday
    $return[] = $easterDate->format('Y-m-d');
    //Pfingstmontag - pentecost monday
    $easterDate = DateTime::createFromFormat('U', easter_date($year) );
    $easterDate->modify('+ 51 days');//go to Pentecost Monday
    $return[] = $easterDate->format('Y-m-d');

    return $return;
}
