Woo-hoo. I won't have to write a NYSE calendar then. Once we start using DateTime (instead of our current Date::Calc and custom wrapper module for business days calculations), we'll need lots of the financial business calendars (NYSE, Federal Reserve, EU (and individual country) "bank" holidays, etc). Good luck getting complete historical information on the NYSE calendar. Some of the holidays were added over the years (for example, MLK wasn't added until 197x). One general comment that reminds me of, anyone writing a "business" calendar, please make sure it is historically accurate (as it will be useless to me (and probably others) if it is not). > Unless it's thought that business calendar manipulation will be more frequent > and useful than Gregorian/Julian/Other calendar manipulation, in which case > now might be the time to make that jump, and rename things... I think it probably depends on the user. For me, like you, business calendar manipulation is much more important than Gregorian/Julian/other.
