The goal was to create a hidden, but feed available list of building hours leveraging capabilities in Livewhale.  These are the steps involved.

Add a new "Event Type" category in Livewhale

Exclude the category 

On the server, edit the /www/html/_ingredients/includes/calendar-settings.php file and add the following

 <arg id="exclude_category">Building Hours</arg>

Create the event

When creating a new event, make sure to select the new event type (see screenshot)


The event will not show up on any public webpages, but will be available via a data feed
