I'd go further and suggest using 1-based indexing for all of these return values, except for clearly-labeled zero-based methods, such as month_0. This seems more self-consistent, and more consistent with human calendar usage.
This also allows us to preserve the use of false return values as an indication of undefined or unknown results, in those cases where an exception isn't thrown.
Nobody ever writes 2002-00-02 or something like that!
Nobody ever writes "the 0th day of the week" either!
