Hey @Greg,
You should be able to pull this off by adding the following code snippet to your theme’s functions.php file:
if ( function_exists( 'Tribe_ECP_Load' ) ) {
/**
* Change the list widget icons' day names to month names.
*
* @link http://theeventscalendar.com/?p=1052743
*/
function tribe_support_1052743( $text, $postDate, $class ) {
return date_i18n( 'M', $postDate );
}
add_filter( 'tribe-mini_helper_tribe_events_ajax_list_dayname', 'tribe_support_1052743', 10, 3 );
}
This works well for me on my own testing site and I hope it works well for you, too.
Let me know!
