There's no way to configure the default view in the Calendar app (though this is on the todo list).

What you could do though is to add a button to a page which links to the day view of the calendar.

So for your site, the target of the link would be /hoperadio/schedule/view?view=day (you can leave the date out of the link and it'll default to today).

If you wanted to create this as a button rather than a normal link, you can use the bootstrap button class for it.

To do this, create a piece of text like "See today's schedule" and use the wysiwyg link button to create the link to the calendar day view. Then in the Advanced tab for the link, add btn btn-primary into the Classes field. This tells the system to create a button, and set it in the site's primary colour.

Another trick, instead of a button, would be to add a Redirect item to your site using the CMS, set the target url to be the day view, and add it to the navigation menu. (then remove the calendar itself from the navigation menu)
