按日期提前自定义字段自定义帖子类型排序

Question

I recently had a list of events that where in date order and worked fine due to the format being numeric, but the client has since changed the output format and now I'm struggling to list out the events in and Ascending date order, this is the new format:

    <?php 

    $posts = get_posts(array(
        'posts_per_page'    => 100,
        'meta_key'          => 'location',          
        'post_type'         => 'events_col',
        'offset'            => 1,
        'orderby'           => 'date',
        'order' => 'ASC'
    ));

    if( $posts ): ?>

Here is the output:

<div><?php echo date("l dS F Y",strtotime(get_field('date'))); ?></div>

the output is all a bit of a jumble I am not even sure what the order is as is illogical!
