[Andy2024]

I have done a calendar at www.suescaravan.co.uk/availability the issue is its showing 2 x July's

 

this is the code

$month = '1';
        $year = date('Y');
          
        for($m=$month; $m<13; $m++) {
          
          $timestamp = mktime(0, 0, 0, $m, 1, $year);
          $daysInMonth = date("t", $timestamp);
          $firstDay = date("N", $timestamp);
        ?>
          <div class="col-xl-4 col-lg-6" data-aos="fade-up" data-aos-delay="100">
              <div class="rounded-3 bg-secondary-subtle">
                <h3 class="mb-0 p-2" align="center"><?php echo date('F', mktime(0,0,0,$m)); ?></h3>
                <table class="table table-bordered m-0" cellspacing="1">
                  <tr>

                </table>
            </div>
          </div>
        <?php
        }
        ?>

 

Ive tried changing 

<?php echo date('F', mktime(0,0,0,$m)); ?>

to

<?php echo date('F', mktime(0,0,0,$m,0,$year)); ?>

but its throwing everything out by a month.

 

Does anyone have any idea what is happening?

Sorted it, had to change

<?php echo date('F', mktime(0,0,0,$m)); ?>

to

<?php echo date('F', $timestamp); ?>
