...and of course Greenwich Mean Time (naval/astronomical, pre-1925),
which looks just like everyone else's notion of the calendar, but which
has the day number increment at noon.
Or the post-1920s Orthodox calendar, which looks like everyone else's
calendar but which sneakily throws off the previous message's regexp for
leap years by having a different rule from everyone else.
(this is fun -- I've got a whole book-ful of these, with conversion
algorithms available for the seriously keen).
Best wishes,
