In this post, I will show you how can you set 
the date range to only three years from the current date in jQuery UI 
datepicker.this jQuey provides two options minDate and maxDate.
For example 
In this code, the DatePicker is selected as 
2009-12-12,change event of StartDatePicker sets the minDate of EndDatePicker.
Here's a good example :
<script
type="text/javascript">
        $(function 
() {
            $(".date").datepicker({
                dateFormat:
'dd-mm-yy',
                minDate:
new Date(),
                maxDate:
'+3y',
                changeMonth:
true
            });
        });
</script>
