How to check if there is a February 29th in between 2 timestamps?

$date_from = \'2007-06-01\';
$date_to = \'2013-05-30\';

    The problem I had was I wanted to find if Feb 29 existed in a smaller date range. It assumes that there is not more than two years. This my solution for that:

    $startDate = strtotime('2015-10-01 00:00:00');
    $endDate = strtotime('2016-09-30 23:00:00');
    $feb29StartYear = mktime(0, 0, 0, 2, 29, date('Y', $startDate));
    $feb29EndYear = mktime(0, 0, 0, 2, 29, date('Y', $endDate));
    
    if( (date('L', $startDate) && $startDate < $feb29StartYear) || 
        (date('L', $endDate) && $endDate > $feb29EndYear)) { //We have a leap day
         //some logic here
    }
    

    Just thought this may be useful for someone else.
