How to 3-way Sync: iPhone, Google Calendars, and iCal
*DISCLAIMER* It is always a good practice to make a backup of your calendars. The reader assumes all responsibility by following the steps listed below and understands that it is their responsibility to backup their files prior to beginning the sync process.
1. Set up your Google Calendars
- If you don’t already have one, sign up for Google Calendar. It’s free and easy to use.
- After you’ve set up your Google Calendar, go ahead and create multiple calendars if you’d like. For instance, make one “Family”, “Work”, and “Church”, etc.
- Click on the down arrow next to one of the calendars and click on “Calendar Settings” 
- Next, scroll down to “Calendar Address” and click on the green iCal button. A dialogue box will pop up. Make sure you copy the full address here!
2. Set up iCal on your Mac
- in iCal, go to the iCal main menu and click on “Preferences”. From here, you’ll click the + sign in the bottom left of the window.

- Under “Account Type”, choose “CalDAV”.
- For your username, use the Google email address that you used to sign up for your Google Calendar account. The password is the corresponding Google password that you chose. For the server, use google.com.
- Click “Create”. You should see some of your appointments populating the calendar at this point (assuming you already added some in Google Calendar).
- Now, click on the “Calendar” menu and then on “Subscribe”.
- In the dialogue box that opens up, paste the address that you copied from your Google Calendar settings.
- Next, click on the main iCal menu and go to “Preferences”.
- Click on the “Accounts” tab and go to the right under “Delegation”; check the boxes next to your Google Calendars so that you can post to them directly out of iCal. After this, you’re finished with iCal.
3. Set up iPhone Calendar
- Click on the “Settings” icon.
- Next, open the “Mail, Contacts, Calendars” menu under “Settings”.
- Under “Accounts”, click on “Add Account”.
- Next, choose “Microsoft Exchange” from the very top.
- For “Email”, use the same address that you used for the Google Calendar.
- For “Username”, again, use that same email address. And for “Password”, use the Google password you set.
- Under “Description”, I recommend labeling it as “Google”. Click “Next”.
- When the dialogue box pops up, click “Accept” and then put “m.google.com” in the new “Server” field.
- The next menu gives you the option to sync your Google Mail, Contacts, and Calendars. For the purpose of this article, turn off Mail and Contacts so that we’re only syncing the calendars.
- Now, open Safari on your iPhone and in the address bar type “m.google.com/sync”.
- From here, choose the calendars that you want to sync on your iPhone Calendar and click “Save”
That should do it! Comment below to let me know if you have any issues, or how easy/hard you thought the whole process was. Once it’s set up, though, you’ll never have to worry about saying “Let me check my iCal when I get home”. Do it on your iPhone. On your Mac. Or on someone else’s computer with Google Calendars.
















Slight panic over loss of Outlook calendar, but found it, merged with Google calendar. (Whew!) GPS faster too.
