Here's a simple example on how this class works :

    // Create a DateTimeImmutable Object
    $date = new DateTimeImmutable('2000-01-01');
    // "Change" that object and assign it's value to a new variable
    $date2 = $date->add(new DateInterval('P6M5DT24H'));
    // Check out the content of the two variables
    echo $date->format('Y-m-d') . "\n";
    // 2000-01-01
    echo $date2->format('Y-m-d') . "\n";
    // 2000-07-07

Note: If you are trying to get 02.29 for non leap year it will return 03.01
Example:
<?php
new DateTimeImmutable('2017-02-29') // 2017-03-01
?>

class MyDateTime extends DateTimeImmutable
{
    public function addDay(int $amount): MyDateTime
    {
        return $this->add(new DateInterval("P" . $amount . "D"));
    }
}

addDay will return DateTimeImmutable not MyDateTime. It looks like there is no "return static;"
i wish i would be
