// or
$nowAirac = $producer->nowByNumber('1804');  
// return Airac with dateStart 2018-03-29 and number 1804

$nextAirac = $producer->next(new DateTime('2018-01-10'));
// or
$nextAirac = $producer->nextByNumber('1801'); 
// or
$airac = $producer->now(new DateTime('2018-01-10'));
$nextAirac = $producer->nextByAirac($airac); 
// return Airac with dateStart 2018-02-01 and number 1802
