This makes eminent sense. We could start with the oldest known calendar

i would disagree. In the same way that we use GMT as standard for time, we

various views that are needed.
After all, a date that is 30,000 days ago -is- 30,000 days ago, no matter
what calendar is used.
1752's interpretation could then be viewed by using a gregorian calendar
package, or a julian calendar package (i presume this is where the
