howdy, i'm trying to disable ALL days in a month except the very last one and not entirely sure how to do it? i've tried things like:

Code:
disabledDates = ['../[^3][^1]'];
but it doesn't work. anyone know how i can do that?
(i'm assuming i'd have to use the date object to getDaysInMonth() for the actual last day but....)
thanx!!
