i am working on asp.net using C# and using jquery datepicker

my question is, how can i disable dates which are federal holidays?

i have a dynamic dates which comes from sql server.

anybody have done something similar or any idea how can i achieve this?

$(document).ready(function () {
$('#endDate').datepicker({ showOn: 'button',
buttonImage: '../images/Calendar.png',
buttonImageOnly: true, onSelect: function () { },
onClose: function () { $(this).focus(); }
});

$('#startDate').datepicker({ showOn: 'button',
buttonImage: '../images/Calendar.png',
buttonImageOnly: true, onSelect:
function (dateText, inst) {
$('#endDate').datepicker("option", 'minDate', new Date(dateText));
}
,
onClose: function () { $(this).focus(); }
});
});
