Script Include:
var ValidationUtils = Class.create();
ValidationUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
validateDate: function() {
var selected_date = new GlideDateTime(this.getParameter('sysparm_expectedDate'));
var requiredDate = new GlideDateTime(); // Todays Date
var businessDays = 7;
var daysAdded = 0;
while (daysAdded < businessDays) {
requiredDate.addDays(1); // Move to the next day
var dayOfWeek = requiredDate.getDayOfWeek(); // 1 = Sunday, 2 = Monday, ..., 7 = Saturday
if (dayOfWeek != 6 && dayOfWeek != 7) { // Exclude Friday (6) and Saturday (7)
daysAdded++;
}
}
var output = {};
if (selected_date.getDate() > requiredDate.getDate()) {
output.correctDateSelected = 'Yes';
} else {
output.correctDateSelected = 'No';
output.requiredDate = requiredDate.getDate().toString();
}
return JSON.stringify(output);
},
type: 'ValidationUtils'
}); 
Client Script:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
g_form.hideFieldMsg('my_datetime');
var validateSelectedDate = new GlideAjax('global.ValidationUtils');
validateSelectedDate.addParam('sysparm_name', 'validateDate');
validateSelectedDate.addParam('sysparm_expectedDate', g_form.getValue('my_datetime')); //Replace your date time variable
validateSelectedDate.getXMLAnswer(function getExpectedDate(answer) {
var validatedOutput = JSON.parse(answer);
if (validatedOutput.correctDateSelected == 'No') {
g_form.showFieldMsg('my_datetime', 'kindly select date after ' + validatedOutput.requiredDate.toString(), 'error');
}
});
//Type appropriate comment here, and begin script below
}

For your requirement you can use OnSubmit catalog client script using GlideAjax and client callable script include.
I have created "Expected Date" field in catalog item for demo. Below client script and script include code is working.
You can also use this onChange client script along with onSubmit client script for better user experience.
OnSubmit Client script -
function onSubmit() {
var validateSelectedDate = new GlideAjax('global.ValidationUtils');
validateSelectedDate.addParam('sysparm_name', 'validateDate');
validateSelectedDate.addParam('sysparm_expectedDate', g_form.getValue('expected_date')); //Replace your date time variable
validateSelectedDate.getXMLAnswer(function getExpectedDate(answer) {
var validatedOutput = JSON.parse(answer);
if (validatedOutput.correctDateSelected == 'No') {
g_form.addErrorMessage('kindly select date after ' + validatedOutput.requiredDate);
return false;
}
});
}
Script include -
var ValidationUtils = Class.create();
ValidationUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
validateDate: function() {
var selected_date = new GlideDateTime(this.getParameter('sysparm_expectedDate'));
var requiredDate = new GlideDateTime(); // Todays Date
var businessDays = 7;
var daysAdded = 0;
while (daysAdded < businessDays) {
requiredDate.addDays(1); // Move to the next day
var dayOfWeek = requiredDate.getDayOfWeek(); // 1 = Sunday, 2 = Monday, ..., 7 = Saturday
if (dayOfWeek != 6 && dayOfWeek != 7) { // Exclude Friday (6) and Saturday (7)
daysAdded++;
}
}
var output = {};
if (selected_date.getDate() > requiredDate.getDate()) {
output.correctDateSelected = 'Yes';
} else {
output.correctDateSelected = 'No';
output.requiredDate = requiredDate.getDate();
}
return JSON.stringify(output);
},
type: 'ValidationUtils'
});
