...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,

Norman
