i had the same problem 2 days ago with a german language website and i`ve found a simple solution.
please see here: http://oenj.justbemotion.com/stockschiessen/ergebnisse-stockschiessen/ (first column, Mrz stands for März)
here is the solution i have used:
<?php $dateStart = date_i18n("d M Y", strtotime(get_sub_field('stcksch_termine_datum1'))); ?> <?php if(get_sub_field('stcksch_termine_datum1')): ?> <?php echo $dateStart; ?> <?php endif; ?>
hope it helps.
EDIT: i have used it as a subfield in a repeater field, so please use get_field instead of get_sub_field.
