You can edit this file: /templates/ja_impact/html/mod_articles_category/events-layout.php
Look for this snippet of code:
// Date
$timestamp = strtotime($startDate);
$day = date('d', $timestamp);
$month = date('F', $timestamp);
change it to:
// Set locale to German
setlocale(LC_TIME, 'de_DE.UTF-8');
// Date
$timestamp = strtotime($startDate);
$day = strftime('%d', $timestamp); // Day as number (e.g., "05")
$month = strftime('%B', $timestamp); // Full month name in German (e.g., "Mai" for May)
