Ciao Hans Interesting points. I understand the idea of temporal regularity and computation for it--not details but the issue.
But because I'm a social scientist I'm coming at the issue from the point of view of recorded empirical mess :-). In transition from Julian to Gregorian, for instance, often parallel notation systems were used that complexify accurate social history dating. And things that are for historians to grasp like why in England & Wales 1751 was only 282 days long :-) Best wishes TT On Saturday, 15 February 2020 19:54:54 UTC+1, HansWobbe wrote: > > Ciao TT: > > You are probably right that there are missing dates in the various > calendar systems. > > For me, that has not been a problems since I almost never need ALL of the > possible dates in a "monotonic Increasing" sequence.
