Not only you, but several users are unable to access Google Calendar worldwide. Navigating Google Calendar through a browser will show you the old fashioned 404 error message.
The app and the website seems to be broken for unexplained reasons leaving people without a schedule. The company confirmed via it’s G Suite Status Dashboard saying, “We’re investigating reports of an issue with Google Calendar. We will provide more information shortly. The affected users are unable to access Google Calendar.”
Users on Twitter began complaining about the breakdown at approximate 10:05 AM EST. Meanwhile other Google services appear to be intact.
Keep revisiting for more updates on this.
UPDATE @ 23:18 Indian Standard Time
The service is now up and running for most users worldwide. Google has verified the same via a tweet and change in the GSuite status dashboard. Most users should see the service recovering gradually.
