Translating the months in release dates

In your child theme's functions.php file add the following:

function ghosptool_translate_months( $date ) {
    // Add all months you want translated
    $current_months = array( 'January', 'February', 'March', 'etc' );
    
    // Add all your translated months in same order with their counterparts
    $translated_months = array( 'Enero', 'Febero', 'Marzo', 'etc' );
    
    $translated_date = str_ireplace( $current_months, $translated_months, $date );
    return $translated_date;
}
add_filter( 'ghostpool_post_meta_release_date', 'ghosptool_translate_months' );
