Adding expiry date gives incorrect error.

[nus-se-bot]

I typed in an obviously invalid day, but get an incorrect error message stating that I am entering the input in the wrong format, either without the hyphens or without some arguments. But in reality, the month and day don't exist.

Team's Response

Bug accepted but severity downgraded to Low since the bug appears "only in very rare situations and causes a minor inconvenience only" since it is expected that most people understand that there are 12 months with 28-31 days roughly per month, so users inputting any other invalid dates are quite rare.

Duplicate status (if any):
