You would add 2 constraints - something like:

$form->constraint( Date => 'start_year', 'start_month', 'start_day' );
$form->constraint( Date => 'end_year', 'end_month', 'end_day' );

If your data already has the date in a single field, rather than 3,
create a Callback constraint, and base the code on the check in
HTML/Widget/Constraint/Date.pm
