Hi @damodar,

please provide more details, is it a variable on a form on a portal or backend form?

For backend you can achieve this with UI Policy and for Portals with Catalog UI Policy.

Example on my variable on a portal form:

or onSubmit Catalog Client Script.

Let me know how does it look and what you think about this.

should only be able to select business days only

Thank you for accepting my response as solution

This is the script include i wrote 

var ValidateCatalogDate = Class.create();

ValidateCatalogDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    isValidDate: function () {

        var inputDateStr = this.getParameter('sysparm_date');

        var scheduleName = this.getParameter('sysparm_schedule_name'); // remove this line

        if (!inputDateStr || !scheduleName){

        return 'false'; //remove || !scheduleName from this line

        }

        var inputDate = new GlideDate();

        inputDate.setValue(inputDateStr);

        var minDate = new GlideDate();

        minDate.addDaysUTC(3);

        if (inputDate.compareTo(minDate) < 0){

        return 'false';

        }

        var dayOfWeek = inputDate.getDayOfWeek();

        if (dayOfWeek == 1 || dayOfWeek == 7) {

        return 'false';

    }

        var scheduleId = '55ebbbf15f002000b12e3572f2b47714';

        var spanGR = new GlideRecord('cmn_schedule_span');

        spanGR.addQuery('schedule', scheduleId);

        spanGR.addQuery('start_date', '<=', inputDateStr + ' 23:59:59');

        spanGR.addQuery('end_date', '>=', inputDateStr + ' 00:00:00');

        spanGR.setLimit(1);

        spanGR.query();

        if (spanGR.next()){

        return 'false';

        }

        return 'true';

    },

    type: 'ValidateCatalogDate'

});

this is the client script  i wrote 

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || !newValue) return;

    var dateField = 'desired_date_requested'; // This should be newValue instead, or g_form.getValue('desired_date_requested')

    var selectedDate = new Date(newValue + 'T00:00:00');

    var today = new Date();

    today.setHours(0, 0, 0, 0);

    var msPerDay = 24 * 60 * 60 * 1000;

    var diffDays = Math.floor((selectedDate - today) / msPerDay);

    if (diffDays <= 2) {

        g_form.showFieldMsg(dateField, 'You cannot select today or the next two days.', 'error');

        g_form.setValue(dateField, '');

        return;

    }

    var ga = new GlideAjax('ValidateCatalogDate');

    ga.addParam('sysparm_name', 'isValidDate');

    ga.addParam('sysparm_date', newValue);

    ga.addParam('sysparm_schedule_name', 'U.S. Holidays'); //remove this line

    ga.getXMLAnswer(function (response) {

        if (response === 'false') {

            g_form.showFieldMsg(dateField, 'Invalid date: Must be a business day (not a weekend or holiday).', 'error');

            g_form.setValue(dateField, '');

            g_form.setValue('due_date', '');

        } else {

            g_form.hideFieldMsg(dateField, true);

            g_form.setValue('due_date', newValue);

        }

    });

} 
but it's not working
