Hi db,
Thank you for your question.
Yes the Appointments calender will be visible on your site but you have to create appointment page that will display in the front end of your site.
To create appointment page go to the following path, check the option “Create an Appointment Page” and save the settings
Admin Area -> Appointments -> Settings -> General -> Display Settings
On saving the settings it will create the appointment page on the following URL
http://yoursite.com/make-an-appointment/
The above created page contains all the required Appointments shortcodes which you can customize by editing it.
You will find more information about the Appointments shortcodes on the following path.
Admin Area -> Appointments -> Shortcodes
Best Regards,
WPMU DEV
