Hey Erik,
Thanks for reaching out to us!
Unfortunately I won’t be able to give you a detailed description on how to accomplish what you’re looking for, hopefully I can help to get you pointed in the right direction.
To start, take a look at our Themer’s Guide to see how to copy template from the core plugin into your theme files.
From there, take a look at our “views > templates > month > single-event.php” file. Using the template at the very bottom, you could customize the link for the event to include a query argument for the date like so:
<a href="<?php echo esc_url( $link . '?date=' . $day['date'] ); ?>" class="url">
From there, you could add a check on the single event template to see if that “date” parameter had been passed. If so, display that date where you would like.
Let me know if this helps.
Thanks!
