ecristoperj,
Very easy. From the “Other Notes” tab of the plugin’s page:
Default vs. Custom Templates
The Events Calendar plugin now comes with default templates for the list view, grid view and single post view. If you would like to alter them, create a new folder called “events” in your template directory and copy over the following files from within the plugin folder (the-events-calendar/views/):
* gridview.php
* list.php
* single.php
* events-list-load-widget-display.php
Edit the new files to your hearts content. Please do not edit the one’s in the plugin folder as that will cause conflicts when you update the plugin to the latest release.
You’ll see an <h1> tag on line 8 of both grid-view.php and list.php. Just swap out <?php _e('Calendar of Events', $spEvents->pluginDomain) ?>
for whatever title you want.
