Question

I am looking for a regular expression to validation Date selected from a datepicker with format of D, dd M yy

 $('#expirydate').datepicker({
        constrainInput: true, 
        minDate: 0,
        dateFormat: 'D, dd M yy'
    });

And the equivalent format in View is like this:

 <div class="editor-label">
    Expiry Date
</div>
<div class="editor-field">
    @Html.TextBox("ExpiryDate", String.Format("{0:ddd, d MMM yyyy}", DateTime.Now), new { id = "expirydate" })
    @Html.ValidationMessageFor(model => model.ExpiryDate)
</div>

I could not get it in the regex library.. can anyone help??
Appreciate any feedback.. Thanks…

If it’s coming from a datepicker, and you trust that it won’t produce impossible dates, then to validate that format you could use:

(Sun|Mon|Tue|Wed|Thu|Fri|Sat|Sun), [1-3]{1}[0-9]{0,1} (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec) \d{4}
