Various and sundry details:

Years must be positive, months must be in the range [1,12], and days must be in the range [1,31]. Insulting errors will be thrown in your general direction for ridiculous dates.

String arguments are in the form year-month-day, and are your responsibility to get correct.  Two-digit years, i.e. "47", mean "47 AD", not "1947".  We're not picky about one-digit months and days.
