My wife and I use Google Calendars to sync and share events and information. Ever since we setup a Bills calendar, it’s annoyed my that it won’t sync to our iPhones. Today, I decided to sit down and figure out how to make it happen for my iPhone and iPad. ((Just replace “iPhone” with “iPad” below.))
By default, only the main Google Calendar is synced to the iPhone. To select secondary calendars, open Safari on your iPhone and go to Google’s iPhone Select page.
Second, still on Safari on the iPhone go to Calendar Sync page and select the additional calendars to sync.
Force quit the calendar app and reopen it or reboot the iPhone. Once that is complete, you should see the additional Google calendars available to sync. Check the ones you want on your iOS device and you’re all set.
