I wouldn't consider this 'support' for Julian dates, anymore than the fact we can enter irregular date support for the Quaker Dating system or the Jewish Calendar. (One big factor is that making a date irregular affects so many things). I am not sure if I have ever seen a program that REALLY handles Julian dates properly (i.e. knows the difference between the types of dates and fully handles the differences). I suspect the problem is that to someone not really aware of the issues, treating Julian dates as if they were Gregorian (which is what most programs do) just seems to work. You will find that many will support the double year notation, as this is a common notational issue, but many assume that it is related to the Julian/Gregorian switchover (which it really isn't, it is caused by the change of the start of year which was forced by the Gregorian calendar, but also occurred prior for some usages, and actually should be used for ANY Julian date in the Jan-Mar time frame where the Julian date uses the March year change, not just those after 1582 unless the program REALLY supports that form of the Julian calendar and treats Jan xxxx as after Dec xxxx). -- Richard Damon
