the datepicker is highly configurable.
to add a year option and set the range from 1930 to 2010 you add the following lines to your code
$(function(){
$('#datepicker_1').datepicker({
dateFormat: 'dd/mm/yy',
showAnim: 'show',
onClose: closeDatePicker_datepicker_1,
changeYear: true,
yearRange: '1930:2011'
});
});
Here is an example, using the code above
datepicker.php
There is a lot of documentation here...
