Question

I try to calculate the easter date in php.

echo(date("2012: t.n.Y", easter_date(2012)).'<br>'); // 2012: 30.4.2012

This date is correct for the eastern orthodox churches. But I want the normal one!

My next try with the easter_days function:

function easter($year) {
    $date = new DateTime($year.'-03-21');
    $date->add(new DateInterval('P'.easter_days($year).'D'));
    echo $year.": ".$date->format('t.m.Y') . "<br>\n";
}

easter(2012); // 2012: 30.4.2012

Tested oh PHP 5.2.6 and 5.3.6. I also tried to change the timezone with no success.

Answer 1

Your date format is wrong. t is the number of days in the given month (april = 30). Use d for day of the month:

echo(date("d.m.Y", easter_date(2012)).'<br>');
// will output: 08.04.2012

btw: orthodox easter date is April 15th this year.
