"What's that?" you said. Yup, remember the Week view we saw in earlier post? Turns out, even when your device is in portrait mode, you can go to the adjacent dates just by swiping left or right. That's right, just like how you navigate pages of apps on the home screen. Should've thought of that long ago, Apple. Just saying.
By the way, when you move an event by touch (see previous post), you can move to adjacent dates by dragging the event to the left or right edge of the screen. Again, similar to how you move an app icon across pages on the home screen.
Have fun!
