Solution Requirements
To get around the static min/max date issue, you're going to create a dynamic from/to date picker. The

•
Restrict the

date when a
from
date is selected; for example, suppose you
selected 20-Jan-2010 as your
from

to
date
picker, he or she can't select anything before 20-Jan-2010 (i.e., the user can't select
any dates from before 19-Jan-2010).
•
Restrict the
from
date when a
to
date is selected; see the previous example in

Support multiple date formats; date formats do not need to be the same for both

from
date is less than or equal to the
to
date
