Hey Pau — nice to see you again and hope all is well!
You can create a template override for this file:
/wp-content/plugins/events-calendar-pro/src/views/widgets/modules/single-event.php
Change this line:
<span
class="list-dayname"><?php echo apply_filters( 'tribe-mini_helper_tribe_events_ajax_list_dayname', date_i18n( 'D', $postDate ), $postDate, $mini_cal_event_atts['class'] ); ?></span>
to this:
<span
class="list-dayname"><?php echo apply_filters( 'tribe-mini_helper_tribe_events_ajax_list_dayname', date_i18n( 'M', $postDate ), $postDate, $mini_cal_event_atts['class'] ); ?></span>
I think we’ve covered template overrides together in the past but here’s a link to our Themer’s Guide just in case. That walks through the process in great detail.
Will that work for you? Please let me know. 🙂
Cheers,
Geoff
