1. The post is referring to a new Android app, not the web UI.

2. The situation you're talking about has existed since... well, it's been there for the last 3 years I've been using Google Calendar. I, too, would like a working back button, but the web UI is effectively set in stone.

The back button issue in the web UI was fixed recently.

You've blown my mind. I feel like I was hitting the back button from an event detail and landing on the New Tab page very recently. Thanks for pointing it out.
