calendaricloudscrolling
I was able to freely scroll forward and backward in time. I can only go forward via the arrow keys one page at a time now. No idea why this is happening.
I tried a workaround at one point by clearing my calendar (methodical removal of plists, etc…) then restoring it from iCloud. After that restoration it didn't work. Next day scrolling worked. Day or two later, scrolling calendar stopped working and still doesn't.
It sounds like you may not have your views set to see the items, or that you have the view in MONTH, and the screen is just too small to show them as a 'boxed' houly appointment. Try enabling all the calendars, or at least the calendar you use, and then check the list or Day view, and see if they show up.
If this is the wrong Idea, can you submit a screen shot of what you see?
This has been bothering me all during the Sierra betas and I couldn't get anyone to address it.
The issue is that there's a minimum scrolling speed now. You can really see it if you use inertia scrolling. You let go and it slows down but then when it gets to a certain speed, it never goes slower than that. And then it stops abruptly at the same time it would have if it had been slowing down normally.
What you're seeing is a side-effect of this. And I haven't found a solution yet.
And this scrolling behavior is ONLY in Terminal as far as I can tell.
Go to bugreport.apple.com. I am filing more reports.

Put two fingers on the page and move it to the left or the right, stop when you want. It is still there. The arrows move a page completely, set to day, week or month when you want to use the arrows.
