sync multiple google calendarsA decent calendar service is indispensable. No matter what alternative I tried using – Windows Live, iCloud – I’ve always turned back to Google Calendar.

By and large, my use of Google Calendar goes without issues or complaints. It’s easy to use, and widely supported. Even most (desktop and mobile) operating systems now provide out-of-the-box support. However, for some unknown reason, synchronising multiple calendars has always been at least a bit tricky to set up. It’s no different for Windows 8.

The default calendar application on Windows 8 looks great, and it takes only a minute to add and sync it with your Google Calendar account. The only problem is that by default only your primary calendar will show up – a problem, to say the least. Below, we’ll show you how to synchronise the Windows 8 Calendar application to as many calendars from your Google Calendar account as you want.

1. Add Your Google Account

You probably already have connected your Google (Calendar) account to Windows 8, either in the Calendar, or in another application. If not, we’ll do so now.

Open the default Calendar application, and go to the application settings using the Windows Charm Bar. You can open the Charm Bar by pressing Win+C, or by placing your mouse cursor in the down right corner of your screen, and moving it upwards.

In the settings pane, go to Accounts, and select ‘Add an account’. Select Google as the account type (as seen in the screenshot above) and enter your credentials. The Calendar app will now start synchronising your main Google calendar to your computer.

2. Change Your User Agent To iOS

A user-agent switcher fools a website into thinking you’re using a different operating browser (or system) than you actually are. In this case, we want to appear as though we’re using a browser on an iOS device (the iPhone or iPad).

Install a user-agent switcher add-on for your browser. You can use the aptly named User-Agent Switcher extension for Google Chrome (pictured above), or User Agent Switcher add-on for Mozilla Firefox. After installing, use the extension or add-on to temporarily change the user agent of your browser to that of the iPhone or iPad.

3. Temporarily Disable JavaScript

Next, we’re going to (temporarily) disable JavaScript. Using Google Chrome, go to Settings -> Advanced Settings -> Privacy -> Content Settings, and select ‘Do not allow any site to run JavaScript‘ (shown below).

Alternatively, in Mozilla Firefox, go to Options -> Content and uncheck the ‘enable JavaScript‘ checkbox.

 4. Change Your Google Sync Settings

After changing your user agent and disabling JavaScript as detailed above, point your browser to m.google.com/sync/settings/.

You should be able to see all devices that are set up to synchronise with your Google account. Windows 8 should be included in this list, but is called ‘WindowsMail’. Click to open.

By default, hardly any settings are visible. Go to the address bar in your browser. At the very end of the URL, change &supportMultiCalendars=false to &supportMultiCalendars=true and press enter. Now, you can see all the calendars associated with your Google Calendar account. Tick off the checkboxes next to the calendars you want to synchronise with the Windows 8 Calendar, and press Save.

5. Revert Your User Agent & JavaScript Settings

Don’t forget to change your user agent back to default (using the same extension or add-on) and reenable JavaScript as you disabled in step three of this article. The next time the Calendar application syncs with your Google account, the other calendars will appear as well.

Do you use the default Calendar app in Windows 8? Let us know in the comments section below the article!

    I am one of the few people that likes IE. I used your instructions and their dev console to make things work. This way you don't have to install another browser or a plugin to that browser. You also don't need to disable javascript for some reason.

    What I did:
    1. In IE 10 in the desktop hit F12 to bring up the dev console
    2. Under tools, change the user agent string to be Apple Safari (iPad)
    3. Navigate to m.google.com/sync/settings
    4. Click into windows mail
    5. In the URL you will see ‘supportMultiCalendars=false’, change that to true and refresh the page
    6. Select calendars you want to share
    7. Restart the calendar application, go into settings ->Options and enable the calendars.

    This method doesn't work on RT, because you can't install Chrome or FF on RT. However, you can use a PC or your mobile phone to configure these settings, and then open the calendar app on your RT device and it will begin syncing with all the calendars you specified.

    I'm not sure what I'm doing wrong, but I can't get your steps or the GSync app to work. I know they seem fool-proof, but the only calendar still visible is my main "Gmail" calendar. Might someone be able to help me?

        I encounter the same problem. I used your way and set everything up but only my regualr google calendar is shown. I tried GSync Manager and there all my other calendars are already activated, but they just won't show up.
        Any idea?

    There is an app called 'gsync manager' that does the same thing, plus a little more and is a LOT easier, thanks for this article tho for getting me to start my windows 8 up into a working machine.

    Instructions weren't working for me so I kept looking for a solution.

    Found: gSync Manager

    Installed and had it working in about 30 seconds.

    Once installed, make selections from your list of subscribed calendars, hit SAVE button, THEN hit sync. Done.

    Pull up Win 8 calendar, it's all there.

      Link: gSync Manager (free) at the Windows Store.

    I'm having a problem adding events to my Win 8 calendar and having it update my google calendar. I didn't do the steps above because I only have 1 google calendar that seems to sync fine with my Win 8 calendar.

    If I add an event on my Win 8 calendar, it doesn't update my google calendar. Is there a 2-way sync available?

    You Sir are a lifesaver! Windows 8 was a thorn in my side without being able to see all my gmail calendars.

    ..... Can you make the crappy hotmail account disappear so I only see my google mail? You know what I mean? In order to set up you gmail account you have to register for a hotmail account and then add gmail afterwards, hence you end up with two blue tabs in the bottom left corner of the mail app within windows 8. All I want is gmail.......??? PLEASE

      you could try to set up your microsoft account with your gmail address, that's what we did.

          Hi,

          Try using https://m.google.com/sync/settings/ instead. I think something changed on Google's end.

          Please confirm if this works for you. Thanks.

          Simon,

          it actually worked the only thing different I had to do is add my account as an exchange account other than that every instruction worked great thank you so much you rock buddy!!

          December 5, 2012 at 9:48 pm

          What problems did you encounter trying to add your account as a regular Google account?

    • Jay
      December 5, 2012 at 3:22 pm

      This does not seem to work anymore. m.google.com/sync redirects to a different page now.

      • Simon Slangen
        December 5, 2012 at 3:52 pm

        Thanks Jay and Chef for catching this. The article has been updated with a new link (one that appears work, at least for now).

          December 5, 2012 at 7:17 pm

          GREAT!!!
          Can't thank you enough for this. This is the only method I've seen that works now.
          Note the javascript has to be re-enabled so you can select the calendar tick boxes. I'm just going try the whole sequence without disabling the javascript so I'll let you know the result.

          Thanks again.
