How to sync your Google Calendar with Windows 8.1: Try OneCalendar

Now that I have a loaner Surface Pro 3, I’ve decided to put aside my Chromebooks(s goog) and use Microsoft’s(s MSFT) new laptop replacement full time. That also means no Chrome as I get re-acquainted with Internet Explorer 11. Yes, I miss my Chrome extensions, but I think I’ll live.

What I can’t live without, however, is my Google Calendar. I’ve got Gmail covered with the native Mail app in Windows 8.1 but Microsoft’s Calendar app doesn’t play nicely with Google Calendar. Or it could be be vice versa; I don’t really care which company is trying to shaft the other here. All that matters is getting access to my events!

While I could just use the browser to manage my Google Calendar, I’d rather live in Microsoft’s world as much as possible when using the Surface Pro 3. After some research, I ended up finding a great replacement app for Microsoft Calendar called OneCalendar. What makes it great? It’s free, it’s touch friendly and it syncs my calendar data both ways.

OneCalendar month

OneCalendar was quick to setup after installing from the Microsoft Windows App Store: I just had to provide access for the app to see my Google Calendar by signing in to Google. After that, my calendars started synching and by calendars, I mean all of them. OneCalendar can pull in any shared Google calendars in addition to your main one. You can select the colors for each one as well.

The app provides multiple views: daily, weekly and monthly. You can tap or touch any event to see additional data. And clicking a blank time brings up the new calendar event form. Here you can add whatever details you need for an event; tap the Save button and the event is added to the appropriate Google calendar.

OneCalendar new event

I’ve created several events in OneCalendar and have seen them quickly sync to other devices such as a Chromebook, Android phone and iPhone(s aapl) 5s. Changes to events made on those devices have also filtered back to OneCalendar without any problems either, so this looks like a great free solution.

The app also supports other calendar types — Facebook(s fb), Exchange,, Office 365 and Windows Live — so the software is aptly named: If you used Windows 8.1, OneCalendar could be the one calendar you use for all events.

    Kevin, you can have chrome on your surface. install chrome desktop browser if you already have not. go to settings and then there would be an option use as windows 8.1 app or something similar. Click it and you would have a chrome book living in surface, complete with dock, extensions and all.
    It will live there until you open explorer. at which point you would have to click that option again other wise have fun.

    • Thanks, Jahangir. Yup, I’m well aware that Chrome can be installed on a Windows device; I used a Surface Pro 2 in the manner you described last year. When I said “that means no Chrome for me”, I meant it was because I was giving Microsoft’s hardware and software a full-time trial. ;)

  2. Kevin, you could install Google Chrome on windows 8 and switch to “App Mode”. bam. It’s a chromebook.

    Don’t kill yourself with IE, okay?

    Otherwise, thanks for the post! I’ve not heard of OneCalendar before.

    Here’s another update after having used this app for a while:
    It can be extremely frustrating to load this app after cold boot. It takes *forever* on my reasonably up-to-date laptop. Once it’s gone through an initial load, though, it seems fine.

    • Mark, if you don’t mind my asking, what country are you in? I know Phil above is in the UK. Curious if the app is only available in certain regions for some reason. Also, what happens if you search the Store app for One Calendar? I’m en route to Google I/O at the moment so I can dig deeper after my 6 hour flight.

    setup one calendar during the setup process (which happened to be the wrong Google account) and now can’t get back to setup to add my other calendars. Does anyone know how to do that?

      You probably figured it out by now. But in case somebody else hasn’t:
      Just swipe in from the right, touch “settings,” touch “accounts,” and the rest is pretty explanatory.

    Here is a rather belated comment, but I’ve just discovered this app, and note that it has a real flaw: it appears impossible to edit or delete previously entered entries.

    Gmail calendars did work with Windows 8 till Google removed support.

    It is really pretty sad what Google and now Facebook seem to be doing to the Windows 8 platform.

    Google is doing all it can to make sure that its users can’t use Windows 8 tablets and phones via only allowing Gmail calendars for people paying a monthly fee to Google and using Google Docs. No Google Maps or other Google apps either for the Windows Metro interface except for Google search.

    Now it seems Facebook is trying to be negative towards Windows 8 platform too via removing WhatApps support which has over 500 million user accounts worldwide.

    Well I’m not re typing my long comment that got lost during the login to comment… :( if it doesn’t support keeping the comment it should make you sign in before allowing the entering of comment.

    Thanks Kevin, you refer to it as being in the Windows App store so it was no problem ontaining; I was in two minds mentioning it but thought it better to than not.

    If you have an iPhone use it accesses your calendar tells you when your meetings are. You’ll never be late, you’ll know how to get there when to set off and always be prepared. Hope this is as useful for you as it is to me!
