How do I view the full Google Calendar website in my BlackBerry Passport's browser? When I go to calendar.google.com, Google brings me to the mobile version.
Try the following URL: google.com/calendar/render
The site will show a dialog asking to confirm using the desktop version. If you click ok, the full calendar site should show up.
Note that the full desktop site may not work fully or it may render slowly on mobile devices. It's a useful site to be able to log into however, as there are many options that can only be set using the full desktop site instead of the mobile site.
This solution was tested to work using the BlackBerry Passport, OS version 10.3.0.908, and the full Google Calendar site is accessible as of December 2014. Your mileage may vary using other versions and if Google decides to change Google Calendar in the future. Best of luck to you!
