Problem with Custom Fields and Events

Hello there people… So this is my frist topic because I’m having a problems with setting up dinamic date onto my wordpress theme… I’m learning to become wordpress developer btw 😀 So here is the problem, I installed ‘Advanced Custom Fields’ plugin to make custom field for my event posts, I made seperate sections outside post and pages for events in wp-admin… So I added new custom field for dates on my ‘events’ and I added manually dates on events which I already created before… and to make it dinamic I edited the code in the theme, but dates just don’t want to change according to those ones which I set them to be… here is the code, I don’t know what am I doing wrong…

<?php

          $homepagePosts = new WP_Query(array(
            'posts_per_page' => 2,
          ));

          while ($homepagePosts->have_posts()) {
            $homepagePosts->the_post(); ?>
            <div class="event-summary">
              <a class="event-summary__date event-summary__date--beige t-center" href="<?php the_permalink(); ?>">
                <span class="event-summary__month"><?php
                  $eventDate = new DateTime(get_field('event_date'));
                  echo $eventDate->format('M')
                 ?></span>
                <span class="event-summary__day"><?php the_time('d'); ?><?php echo $eventDate->format('d') ?></span>
              </a>
              <div class="event-summary__content">
                <h5 class="event-summary__title headline headline--tiny"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h5>
                <p><?php if (has_excerpt()) {
                  echo get_the_excerpt();
                }
                  else {
                    echo wp_trim_words(get_the_content(), 18);
                  }
                ?><a href="<?php the_permalink(); ?>" class="nu gray">Read more</a></p>
              </div>
            </div>
