Welcome to Android Central! On your Bionic, open the Calendar app. Check the app's menu--is there an "Export" option? If there is, see if you can export the entire Phone Account calendar to storage. You'd then have to transfer to that file to your computer, either by connecting the phone to your computer via USB and using Windows Explorer to drag and drop, or by uploading the file to a cloud service like Google Drive and then downloading it again to your computer.
Once it's on your computer, open Google Calendar on your desktop browser, and click on the dropdown arrow next to "Other Calendars" in the left column. Click "Import," then select the calendar file you exported. If you're able to import the calendar into Google Calendar, it should then sync to your Note 3.
