Hi Ben,
You can include the gridview.php file anywhere on your website and display the calendar. You can do that with something like this:
include('wp-content/plugins/the-events-calendar/views/gridview.php');
You would either want to add that directly to something like your page.php theme template file or throw it in a hook. If you only want it showing on the home page you would use this conditional code:
if(is_front_page() || is_page('home')) {
include('wp-content/plugins/the-events-calendar/views/gridview.php');
}
I hope that helps!
