    RequiredFieldValidator adds a Jquery reference by default. So if you have your jquery references in head section of page then the control wont work.  Reason is Jquery wont work will duplicate references. See the below image for more details


    Move the Jquery reference from Head section to end of page or after form tag like below

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <form id="form1" runat="server">
                <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox1">
                <input type='text' id='cal1' />
        <%--  Moved from head section to here--%>
        <link href="https://code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css" rel="stylesheet" type="text/css" />
        <script src="https://code.jquery.com/jquery-1.11.3.js"></script>
        <script src="https://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
            $(document).ready(function () {
