```[How about a Mathematica solution to this. - moderator]

Some of the hp calculators have this date function ... basically AFAIK julian
date has 36525 days per century ... it starts somewhere ca 4713 BC [?] and
is off by about a day in 128.2 years or a moon in 3786.0 years or a month in
3902.6 years ... something like that, because our tropical calendar has
365.2422 days in a year ... though then again, the Gregorian calendar has
365.2425 days in a year, reducing the discrepancy by 4% ....
