For example, it would get hopelessly confused (loop or crash or report wrong data, I don't know what) if given an implementation that accurately implemented the calendar used in the English colonies in America before 1750, where the year began on March 25.
Nitpick - the last year starting on March 25th in England was 1751 (which was therefore only 287 days long, much less than the 355 days of 1752).
One other data point: in all of these other systems, leap years are not even a multiple of 4,
Right: the leap day previous to 1752-02-29 was 1747-02-29, 24 days before the end of 1747. -- Clive D.W.
