Keep iCal and GCal in Sync For Free

The blogs have been buzzing as of late about Google’s introduction of the CalDAV protocol into its Google Calendar service. For those of who who live on the planet Jupiter, Google Calendar is the excellent free online calendar service that resides in the cloud. One of the major trends in technology is maintaining a connection between apps in the cloud, and apps on your physical machine. With the introduction of CalDAV to Google Calendar, it’s never been easier to keep iCal and Google Calendar in sync, let alone for free.

For the people that don’t feel like shelling out for Apple’s push-enabled MobileMe service, Google offers a highly competitive set of services that rival Apple’s. For the low price of $0.00, you can have all of your iCal appointments synced up to the cloud. Additionally, any changes you make to Google Calendar online will be pushed down to your iCal calendar on your Mac. While it doesn’t offer the same instantaneous changes as MobileMe claims to offer, the 15 minute interval default sync time should be more than enough for some.

Integrating Google Calendar with iCal is as simple as adding an account to your iCal preferences. After you open the preferences in iCal, click on the Accounts tab. Hit the “+” button to get the “Add an Account” dialog box. For the username option, put in your full Gmail address (including the @gmail.com), followed by your password. Additionally, you have to put in the address for the Account URL. This address can be found here: https://www.google.com/calendar/dav/[YOUR USERNAME]/user (just replace the [YOUR USERNAME] with your own Gmail address). Again, this should include the “@gmail.com” at the end of it.

After following those simple steps, you should be up and running. You can sync manually by clicking Command+R and you can also change the sync interval. With the iPhone Google interface, and Google Sync app for BlackBerry, you can truly have your calendars in sync everywhere. I have a strong feeling that Apple will allow native syncing to the iPhone with a future update. That would make it even easier to make sure that you never have a reason for missing an appointment again.

    This doesn’t work nearly as well as I had hoped. It only syncs once calendar and it’s not an existing calendar, you have to put events in from scratch. Or am I missing a setting?

  2. Ash on August 4th, 2008 8:38 am

    Yes I agree with the previous post. Does anyone know how to sync multiple Google Calendars?
    Thank you.

    I’ll stick with BusySync – http://www.busymac.com. It’s been fast and reliable for me. Does multiple calendars, LAN and costs less than SpanningSync.

    You can sync multiple calendars. Here’s a link to how-to:

    The problem is there is a know issue where your default calendar won’t sync both ways (only from iCal to Google calendar). Google says this is an Apple problem so it may not be fixed anytime soon (then people wouldn’t use Mobileme).

    Btw Calgoo Connect is free now. It can sync multiple calendars both ways and it has been working great for me.

    Syncing multiple calendars is really easy. Just add each calendar as a separate account. It works perfectly.

    There’s full instructions at:
    http://www.google.com/support/calendar/bin/answer.py?answer=99358

    Look at the bottom section entitled “Add secondary calendars”

    Dermah – You can use existing calendars perfectly easily, no need to have to make a new calendar.

    Another feature you don’t mention here is that now your calendars are in iCal, you can use iSync to update them to your mobile phone. I haven’t tried syncing back from my phone to the calendar but frankly I would never do that anyway.

    Not very useful until multiple calendars can be sync on one account. I don’t like anymore clutter than necessary in ical.

    Jake, I just tried this and it works fine! I have 3 calendars from my Google account in iCal, plus my wife’s account (which I have permissions to access).

    It is a nice thing if you want to manage a public calendar over google and iCal but for everything else it is useless.

    Thanks for the tip! i like it and i will activate it right now!

  13. Drew on September 10th, 2008 9:05 pm

    I’ve successfully added 2 primary Gcal calendars (mine and my wifes) to iCal, but they don’t sync 2-way.

    Also, I’ve tried adding one secondary calendar, but it keeps asking for the password (I’ve made it public in gCal settings.

    Apparently this only works in limited situations. And mobilme SUCKS. Oh well.

    For those confused by the options and multiple calendars – Google have released a tool to set it all up for you based on your Google Apps login:

    Worked for me without a hitch, and on a Google Apps for Business account as well.

    Is it possible to make gcal send an email each time theres made a change in the calendar?
    We have a calendar that we share between 10 people. If one adds something it would be great for all the others to automatically receive an email with the changes. In that way we don’t need to check that cal. daily.

    I could sync the gcal with my ical. the ical has this “automatic notification on changes- feature”

    - nut isn’t there a direct way using only gcal?

    thanks!

    Thank You SOOOOOOOOOOOOOOOOOOOOOOOOOO Much!

    I just wanted to throw out a little something I ran into. When Google calendar is open in a browser iCal can not find the calendar. Closing the window solves the problem. Hope this helps. Also it is possible to receive e-mail notification to changed invitations on Google calendar. It is under settings then notifications for each individual calendars I have only used it a couple of times but it seems to work well.

    While what you suggest is one way of tackling this problem. I struggled to find a reliable way to do this.

    What I found was that SpanningSync was the best means for keeping my address book, ical, gcal and iPhone in sync.

    Well worth the (I think) 30 I paid for it.
