Build an Easter date with DateTimeImmutable

easter_days() is useful when you want the result in PHP's configured timezone or need years outside the practical Unix-timestamp range of easter_date().

$year = 2027;
$base = new DateTimeImmutable("$year-03-21");
$days = easter_days($year);
$easter = $base->add(new DateInterval("P{$days}D"));
echo $easter->format('Y-m-d');
