How to Sync Your iPhone Calendar With Your Google Calendar
Apple’s iOS operating system supports connections to Google accounts. To sync your iPhone and Google calendars:
Limitations
Google Calendar supports several features that do not work on Apple’s Calendar app, including the room scheduling tool, the creation of new Google calendars, and the transmission of email notifications for events. To use the features, you must access your Google account. When the sync is complete, Gmail appears in the Calendar list.
Can You Sync Multiple Google and Apple Calendars?
Got more than one Google account? You can add as many Google accounts as you want to your iPhone. The calendars from each account will be visible in the iOS Calendar app.
Google Calendar and Apple Calendar Bidirectionality
Neither Apple nor Google supports the merging of calendars, although merging calendars is possible using some workarounds. So, because each calendar is separate and has different security requirements, you can’t see any non-Google calendars loaded on your iPhone from within your Google account.
Alternatives for Syncing Google Calendar to an iPhone
Google offers a version of the Google Calendar app for iOS in the App Store, and several other developers offer iPhone apps that integrate with Google Calendars. For example, the Microsoft Outlook app for iOS integrates with both Gmail and Google Calendar. Either of these is a good choice for people who want to access their Google Calendar but prefer not to use the stock iOS Calendar app.
Tips for Syncing Calendars on Your iPhone
Only sync the calendars you know you’ll need on your phone. Calendar items generally don’t hog space unless you have a ton of attachments in your appointments. However, the more devices that sync to a calendar, the more likely it becomes that you’ll run across a syncing collision. Limiting your iPhone to just the necessities reduces the risk that other calendars will incur a sync error.
