Google Calendar (ICAL): People who are signed in to Google Calendar can add to your public calendar.
Another application (XML or ICAL): In order to view and subscribe to your calendar using calendar applications like Outlook or Apple Calendar. You’ll need to choose the format (XML or ICAL) that matches what your calendar application uses. Note: The ICAL link downloads a file that ends in “.ics”.
