Not sure if Tokyo is one, but there are calendars where alot of holidays are decreed by the ruler of the country or calculated in some other fashion not knowable in advance of some event (usually the beginning of the year). We currently have 355 different business day calendars supported (exchanges, banks, national, and "hybrid"). Business day calendars are extremely non-trivial to keep updated and accurate. That's just talking about days - it gets worse if you start dealing with business hours. > I assume that the differences between the US exchange calendars > basically boil down to: > - Different holidays > - Different opening hours > - Different week numbering scheme Yep.
