This is an awesome way to interface with your calendar. But for me (on Safari 10 on a 2015 MacBook Pro), zooming (via scroll) was too slow (like, 1. do 2 finger scroll on trackpad; 2. wait 3 seconds for it to finish the animation 3. scroll in more because it didn't go far enough). Maybe I'm too caffeinated or maybe there's some Safari/Mac related thing making it slow, but I would need much faster zoom-in/zoom-out for this to be usable.

But otherwise, super innovative!
