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.  Since I merely need 
some very precise dates in the series of all possible dates, I simply 
create a new (ragged) "base" that skips values I do not need and then use 
positional notation to encode and decode the values I want.  That approach 
also allows me to "level out" spikes in frequently occurring values by 
inserting Past and Next values in the "base" coefficients as "mid-points".  
This quickly becomes a type of binary search that effectively reduces 
processing needs.  Finally, since symbols can be thought of as "prime 
numbers", the benefits of using 
https://en.wikipedia.org/wiki/P-adic_numbers are easily attained.  

All of this works amazing well in TiddlyWiki and significantly reduces my 
longing for the good old days of APL.

Cheers,
Hans
