The code used to validate the month/year of a credit card for processing a charge is not correct.

The expireDate value is being computed as the 1st day of the month. A credit card is valid until the last day of the expiration month.

This prevents using a valid credit card in the month the card expires.

Code:

        public ActionResult ValidateCCExpirationDate(int? ExpirationMonth, int? ExpirationYear)
        {
            if (!ExpirationMonth.HasValue || !ExpirationYear.HasValue)
                return Json(false, JsonRequestBehavior.AllowGet);

            // must be a future date
            var expiryDate = Misc.GetStartOfDate(new DateTime(ExpirationYear.Value, ExpirationMonth.Value, 1));

            return Json(expiryDate > DateTime.Now, JsonRequestBehavior.AllowGet);
        }

Hi Joe,

I think this makes sense to have the end of the month date as the expiration for a card. I have logged an issue to investigate for a future release. Thanks for pointing that out.

For now, you can apply a workaround something like this:

Update the following line of code inside ValidateCCExpirationDate function

Code:
var expiryDate = Misc.GetStartOfDate(new DateTime(ExpirationYear.Value, ExpirationMonth.Value, 1));


to

Code:
int day = DateTime.DaysInMonth(ExpirationYear.Value, ExpirationMonth.Value);
var expiryDate = Misc.GetEndOfDate(new DateTime(ExpirationYear.Value, ExpirationMonth.Value, day));

Wouldn't that still cause validation to fail on the last day of them month? Seems like the time should be the end of the day, not the start of the day (or perhaps the start of the next day).

Nice catch! Yes, this will expire the card on the start of the last day. I just updated the code above to use the GetEndOfDate instead. Thanks again for correction!
