Hey Frank,
When it comes to customizing this title on the front-end of your site, we have a Knowledgebase article on the topic here → https://theeventscalendar.com/knowledgebase/altering-or-removing-headings-on-calendar-views/
That should be quite handy.
As for customizing things in the HTML title element of the document, this requires some more custom coding and would basically mean just writing custom titles in a filter for wp_title(). The trick is to assign a priority lower than 1000 so that it shows correctly.
I demonstrated how to make this sort of customization in a custom Plugin for you, which you can check out here → https://gist.github.com/ggwicz/b8a6bceaba0edd9efa2a
You can literally install that as a plugin on your site, or copy the code starting with if ( function_exists( ‘tribe_get_events’ ) ) : right in your theme’s functions.php file, and see this change your event titles. Then just customize the titles to your liking.
I hope this helps!
Cheers,
George
