function ValidateVenueDate() 

{

    var startDate = document.getElementById("txtSdate").value;

    var endDate = document.getElementById("txtEdate").value;

    CheckDates(startDate, endDate);

    

}

function CheckDates(strdate,enddate)

 {

    var sd = strdate.slice(3, [5]);

    var ed = enddate.slice(3, [5]);

    var sm = strdate.slice(0, [2]);

    var em = enddate.slice(0, [2]);

    var sy = strdate.slice(6, [11]);

    var ey = enddate.slice(6, [11]);

    var start = new Date();

    start.setFullYear(sy);

    start.setMonth(sm);

    start.setDate(sd);

    var end = new Date();

    end.setFullYear(ey);

    end.setMonth(em);

    end.setDate(ed);

    var oneDay = 1000 * 60 * 60 * 24;

    var difMilli = Math.ceil(end.getTime() - start.getTime());

    var diff = Math.round(difMilli / oneDay);

    if (diff < 0) 

    {

        alert("End Date Should come after Start Date");

        return false;

    }

}
