There are some user interface experts who say that there is no such thing as a user error, only usability errors.
While no system is completely idiot-proof (especially for an idiot this clever), they still could have done a better job. It’s good that they highlight in red the non-conforming field, but the error message says “Please enter a valid date”, leading the user to conclude incorrectly that the date itself was a problem, not the “Month” field.
They also could have used the international standard format, YYYY-MM-DD.

User just can’t read, would have found a way to mess up any interface. YYYY-MM-DD would have probably been filled in 0005-16-99
