Howdy again aovivo,
That is very good question. I think that we should consider adding the event date to that email by default, and that is something I am going to run past the team at our next meeting. Of course even if they all agree it will take a little bit to develop, test for bugs, and integrate into a future release. In the mean time here is what you can do:
1. Following the themer’s guide create a custom template for this file: /the-events-calendar/views/tickets/attendees-email.php
2. Within your custom template add this line where ever you would like the date to appear: <?php echo tribe_get_start_date( $event, true ); ?>
That’s it! Please let me know if you have any questions or troubles along the way, or if there is anything else. Thanks!
