You can easily translate the article date to your language of the Meteor Joomla Articles element of Quix.

Open the meta.php file from the templates > tx_meteor > quix > meteor_joomla_articles > blocks from the website root direcotry.

Now copy & paste the code:

<?php
    setlocale(LC_TIME, "es_ES");
    $artTransDate = strftime($field['date_format'], strtotime($item->displayDate));
    echo $artTransDate; 
?>

Instead of the code place:

 <?php echo $date->format($field['date_format']); ?>

Now write your language tag instead of es_ES. The language tag you will get to the site adminstrator panel. Just navigate to Extensions > Languages and copy & paste the language tag to the corresponding place.

Now go to the Meteor Joomla Articles element Styles tab, paste the code %d, %B %Y in the Date format field.
