Is there any known algorithm between the Gregorian and the other calendars ?
I did some searching and reading, and it kind of seemed like even experts hadn't worked it out. But maybe I was running down the wrong rabbit hole? The formulae I found came with the caveat that they might be a day or two off! Recall that TW's internal dates are only good for about 200 years back. One workaround might be to use a data dictionary with all the dates for some desired period of time pre-translated between systems.
