<script type="text/javascript">
gform.addFilter( 'gform_datepicker_options_pre_init', function( optionsObj, formId, fieldId ) {
    if ( formId == 10 && (fieldId == 30 || fieldId == 32) ) {
        var ranges = [

                if ( date >= ranges[i].start && date <= ranges[i].end ) return [true, ''];
            }
            return [false, ''];
        };
        optionsObj.minDate = ranges[0].start;
        optionsObj.maxDate = ranges[ranges.length -1].end;
    }
    if ( formId == 10 && fieldId == 30 ) {
        optionsObj.onClose = function (dateText, inst) {
            jQuery('#input_10_32').datepicker('option', 'minDate', dateText).datepicker('setDate', dateText);
        };

</script>

Be sure to change the dates, the form ID and field ID for the two fields.
