Hi @tebbott
Using the strtotime function should work like this:
<?php
$date = get_field('date');
// $date = 19881123 (23/11/1988)
// extract Y,M,D
$y = substr($date, 0, 4);
$m = substr($date, 4, 2);
$d = substr($date, 6, 2);
// create UNIX
$time = strtotime("{$d}-{$m}-{$y}");
// format date
echo date('d/m/Y', $time);
?>
Good luck!
Cheers
