Alan,
Francisco: "I don't understand why you need so many different calendars. For the example that I first posted (adjust a schedule to the japanese calendar), you suggested that the Japanese imperial calendar would need to be implemented. I would like to know what kind of applications are you dealing with, in which expressing the dates in the original calendar is important. For a financial application, the japanese calendar is just another gregorian calendar with certain dates defined as bank holidays."
By the way, the Japanese calendar in last 100 year or so uses the same day and month as the Gregorian's, but the years are counted differently. If someone is writing an application that will be used by a financial institution or a school or such, it should handle that. For example, today (Apr 26th, 2006) is 18th year of Heisei, 4th month, 26th day, but 20 years ago was 61st year of Showa, 4th month, 26th day.

In that case, adding a subclass of Calendar class to support the Japanese calendar would be relatively easy to do. And if the issue is holidays, those usually occur according to the same annual-recurrence rule each year--so the Gregorian calendar could be used.
