Hello, up to now, most of the work appears to have gone into the time scale stuff - providing an API to map various date and time representations to each other.
I'd like to see another important aspect of calendars (namely the Gregorian calendar) covered in the DateTime framework, too: defining all sorts of holidays. Lots of applications need to tell business days from public holidays, and calendrical displays for humans in fact show holidays by their name. Of course, this needs layers of localization and customization as well as additional basic algorithms (like calculating the date of Easter). Where should all that go? Unfortunately (in my opinion), the DateTime::Calendar namespace seems to have been assigned to alien time scales rather than to whatever a time scale additionally needs to make up a calendar. It might be feasible to separate date calculations (depending on what calendar is used) from nomenclature issues (depending mostly on locales). Ideas, anyone? -Martin
