The Julian-Gregorian transition certainly depends on what country you're
thinking of; it can depend on what part of what country (e.g. Alaska, which
changed when USA bought it from Russia). See the Explanatory Supplement to
the Nautical Almanac and Astronomical Ephemeris (or is it the ES to the AE
and NA - I don't have a copy by me) for a long list. Of course real computer
people will have programmed the dates of Easter (both Western and Orthodox),
Passover, Ramadan, ... as well.
