Deque has a very good example of how to properly implement a date picker.

Ach! Donnerwetter!
ARIA is not used properly.
The table with role="grid" has aria-readonly="true" which is probably what is preventing screen readers from going into forms mode.

It uses aria-activedescendant to manage focus, I'd have to see the JavaScript to determine whether the id target for that attribute is being correctly updated as user presses the arrow keys (the ID should be updated to point to the active cell in the grid as the user navigates within it).
But I see a warning sign that the grid itself is not in focus order, which is necessary for aria-activedescdnant to work, see:

The divs turn buttons you mention need to have both an onclick event as well as an onkeypress listening for the appropriate keys (13 for enter, 32 for spacebar).
This one will need some ARIA TLC.
