has regular expressions for almost anything. There is one on there that does exactly what you want. Look under Date/Time.

Why use a regex for date validation? Why not use a CompareValidator?

e.g. (http://stackoverflow.com/a/939852/884561)

<asp:CompareValidator
    id="dateValidator" runat="server" 
    Type="Date"
    Operator="DataTypeCheck"
    ControlToValidate="txtDatecompleted" 
    ErrorMessage="Please enter a valid date.">
</asp:CompareValidator>
