it is no more than about 20 lines of code, from a parsed date.
and an option on a control card whether to use the RR built-in code or the
application hand-made code. Both are nice and easy.

actually it is better to have the starting days of the months in a list,
i.e. 0,31,59,90,... for a non-switching year, but 0,31,60,91,... for a switching
year.
