Bryan,
Yes this works alright but a couple of observations
- all dates are exposed as links but one cannot tab from one date to
the next as one does between links
- non-selectable dates should be navigable to but not selectable
- admittedly, there are UA / At limitations like up/down key allows
one to navigate a column (day of week) only with JAWS in IE and with
NVDA in FF.
