Nor do I, Richard. But TMG does have a way to "indicate" that a date is Julian (aka Old Style), which is what you asked for. Are there problems with using an irregular date in TMG? You bet! But can you "indicate" that a date is Julian (aka Old Style) in your TMG report output? Yes. It all depends on what you meant by "indicate". > ... treating Julian dates as if they were Gregorian > (which is what most programs do) just seems to work. Yes, which is also what TMG does with single year dates. > ... 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... > 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... And as I noted earlier, the only function of the "Old style date range" in TMG's Preferences is to recognize three "short hand" data entry codes as specifying a double year notation instead of their "normal" data entry meaning when entered within that date range. That preference setting really has nothing to do with the Julian/Gregorian switchover, although that is what most users "think" it is for. It is simply a way to provide data entry of double year dates. In TMG you could expand the "Old style date range" to a very wide range of years. Then those three data entry codes would trigger double year notation throughout that date range. The consequence of doing that is the '/' and '-' codes to enter a "between" range of dates now can not be used within that date range. Instead the textual data entry formats for "between" would have to be used. What date range will aid the data entry of the kinds of dates a user usually encounters is up to the user. Michael
