Here i have \"From Date\" and \"To Date\" with submit button. And i\'m using telerik radate control for this project. So, I couldn\'t add that telerik control.
var toDate= urToDate;
var fromDate= urFromDate;
fromDate.setMonth(toDate.getMonth()+13);
if(fromDate>toDate)
{
//Do your work
}
else
{
//from date is older
}
