Inaccurate error message for invalid date

[tengcharmaine]

When testing for how you handled invalid dates, the error message shown was about having an incorrect format instead of invalid dates. You may want to edit it such that it tells the user that the date they inputted is invalid straightaway instead of giving the current error message. This is because users might not be able to resolve their mistake even if they followed the instruction of the current error message. See the screenshot below for more details.
