hi,
i have an issue to count the difference in the october month.

<?php $date_from = get_field( 'retreat_date_from' );
$date_to = get_field( 'retreat_date_to' );

$date_1 = new DateTime(date('Y-m-d', strtotime($date_from)));
$date_2 = new DateTime(date('Y-m-d', strtotime($date_to)));

$days = $date_1->diff($date_2)->days;
?>

HTML
<a href="<?php echo the_permalink(); ?>"><h3 class="uk-card-title uk-margin-remove-bottom"><?php echo $days; ?> Tage <?php the_title(); ?></h3></a>

the october date returns 0 Tage and 1970-01-01

var_dump($days, $date_from, $date_to, $date_1, $date_2);
returns:
int(0) string(10) “10 Oktober” string(15) “14 Oktober 2018” object(DateTime)#4743 (3) { [“date”]=> string(26) “1970-01-01 00:00:00.000000” [“timezone_type”]=> int(3) [“timezone”]=> string(3) “UTC” } object(DateTime)#4744 (3) { [“date”]=> string(26) “1970-01-01 00:00:00.000000” [“timezone_type”]=> int(3) [“timezone”]=> string(3) “UTC” }

maybe someone can help me

kind regards

strtotime() requires specific date formats and your fields are probably not returning the date in a format that can be used. http://php.net/manual/en/datetime.formats.date.php, looking at your return values of 10 Oktober and 14 Oktober 2018 are in any of the correct formats.

Hi John,

thank you for your response. I have fixed this issue with ->

<?php
                $date_from  = get_field( 'retreat_date_from' );
                $date_to    = get_field( 'retreat_date_to' );
                $date_1     = new DateTime(date('Y-m-d', strtotime($date_from)));
                $date_2     = new DateTime(date('Y-m-d', strtotime($date_to)));
                $days       = $date_1->diff($date_2)->days + 1;

                 // var_dump($days, $date_from, $date_to, $date_1, $date_2);
                 // var_dump(strtotime(get_field('retreat_date_to')));
              ?>

              <div class="uk-card-body uk-padding-small">
                <span class="location-card"><?php the_field('retreat_location'); ?></span>
                  <a href="<?php echo the_permalink(); ?>"><h3 class="uk-card-title uk-margin-remove-bottom"><?php echo $days; ?> Tage <?php the_title(); ?></h3></a>
                  <p class="uk-margin-remove-top"><?php echo date_i18n('j F', strtotime($date_from)); ?> - <?php echo date_i18n('j F Y', strtotime($date_to)); ?></p>

                </div>
