PHP: How to correctly send a date in a POST request?

Question

PHP

Please help me with the task.
I am making a PHP script to send a POST request to the official website of the Ukrainian Railways to get information about the availability of trains.
But I constantly get in response "Invalid departure date entered"
The script parses the session id with cookies and the token is also on the site with tickets
. I also looked at what the browser sends to the server.
And entered the same parameters and header.
In short, this is the request:

// Пост запрос
$url = 'http://booking.uz.gov.ua/ru/purchase/search';
$data = array('station_id_from' => '2200001', 
              'station_id_till' => '2208001',
              'station_from' => '%D0%9A%D0%B8%D0%B5%D0%B2',
              'station_till' => '%D0%9E%D0%B4%D0%B5%D1%81%D1%81%D0%B0',
              'date_dep' => '20.06.2015',
              'time_dep' => '00%3A00',
              'time_dep_till' => '',
              'another_ec' => '0',
              'search' => '');

$options = array(
    'http' => array(
    'header'  => "Host: booking.uz.gov.ua\r\n".

'method'  => 'POST',
        'content' => http_build_query($data),
    ),
);

$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);

// Обработка результатов
$inp = $result;
$s = preg_replace('/\\\u0([0-9a-fA-F]{3})/','&#x\1;',$inp);
$s = html_entity_decode($s, ENT_NOQUOTES, 'UTF-8');
$s = json_decode($s);
print_r($s->value);

Tried everything also on http-master.com in response again wrong date.

I do not see any problems with the date.

<?PHP 
$ch = curl_init('http://booking.uz.gov.ua/ru/purchase/search/');
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array
(
    'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*;q=0.8',
    'Accept-Language: ru-RU,ru;q=0.8,en-US;q=0.6,en;q=0.4,bg;q=0.2',
    'Accept-Encoding: gzip, deflate',

  'Referer: http://booking.uz.gov.ua/ru/',
  'GV-Screen: 1920x1080',
  'GV-Referer: http://booking.uz.gov.ua/ru/',
    'Accept: */*'
); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'station_id_from=2401406&station_id_till=2020891&station_from=%D0%91%D0%B8%D0%B3%D0%B0%D0%B9%D0%BB%D1%8F%D0%B9&station_till=%D0%9C%D0%B0%D0%B2%D1%80%D0%B8%D0%BD%D0%BA%D0%B0&date_dep=21.06.2015&time_dep=00%3A00&time_dep_till=&another_ec=0&search=');
curl_exec($ch);
?>

A json file is returned, indicating that there are no suitable trains...
