Does each Course have a repeater field with multiple dates in it or have you created multiple courses with the same name that have a different date assigned to them?
You could do something like this to get all courses after today:
$today = date( 'Y-m-d' );
$args = array(
'post_type' => 'course',
'meta_query' => array(
array(
'key' => 'course_date',
'value' => $today,
'compare' => '>=',
'type' => 'DATE'
)
)
):
$query = new WP_Query( $args );
Note: the ‘key’ would be your ACF field name that contains the date. You may need to adjust the format of the date.
