I need dates in a 64-bit string. Calendar_64 does just that.
Why I need dates in a 64-bit string? Short version of a long story:
to store then in Mneson vertices as 64-bit integers.
Why I use a modular type instead of a record with rep. clauses? More
practical. (And I think safer, I think rec. rep. clauses are not as
strongly required by the RM to be met by the implementation, which is
yes very strange, but that's the reading of the RM I have, maybe I am
wrong.) On the practical side, I particularly like that the
predefined binary relations for the modular Time type can be used as is.
