Different Google Calendar extensions

Hi I'm Jason Savard the developer of the calendar extension "Checker Plus for Google Calendar" and not the developer of the extension called "Google Calendar" which was recently announced that the developer Manas Tungare will be unpublishing. You may have been confused because my name appears in a comment on the unpublishing note.

I welcome you to try my calendar extension, it also has the agenda view and many more views and options. It's also been around for 10 years and I support all my users everyday with fixes and new features.

You can install it from the Chrome Store here:



  • I recently switched to your app due to that announcement. It was working GREAT until today. Now I keep getting notifications for my events that have an error. I don't know what the error is for, and thus don't know how to fix it. And I can't tell it to STOP notifying me for this event because there is no way to hit the checkmark. (Picture attached).

    I have trying refreshing, and also Granted Access Again. Nothing is fixing the error.I would rather not have to find a new app, but I also don't want to keep getting notifications like this.

  • @Jondi Soper Good news you've sent me just the right details that I was able to fix this bug immediately, you can force the update to v27.4.6 with these instructions: https://jasonsavard.com/wiki/Extension_Updates

  • I have the same error now, are you able to fix it with this information?

  • @Henrik Ok good news I just pushed v33.0.4 with a fix for this, you can update the extension with this: https://jasonsavard.com/wiki/Extension_Updates
