Hi @pagol
You need to check out the orderby parameter of wp_query.
I haven’t tested this code and you might need to set the order parameter to either ASC or DESC as well. But give it a go:
<?php
$args = array(
'cat' => 'event',
'posts_per_page' => 2,
'orderby' => 'meta_value',
'meta_type' => 'DATE',
'meta_key' => 'fieldnameofdatepicker'
);
$news = new WP_Query($args);
?>
<?php while ($news->have_posts()) : $news->the_post(); ?>
<li>
<h3><?php the_field('date'); ?></h3>
<h4><?php the_title(); ?></h4>
</li>
<?php endwhile; ?>
