Re: Acessibility of 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:
http://www.w3.org/TR/wai-aria/states_and_properties#aria-activedescendant

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.
