Review Comment:
Years must be not 4 characters long, since date 1-1-1, 45-10-20, 457-05-16,
896-08-01 are valid dates, and as we allow the month and days to be one or two
characters long it would be strange to say, years must be at least 4 character
long, but it can be 10 character long. Most of the programming languages
support dates up to years 9999 or even less, so we are good with that limit.
