+With the Milesian calendar, a proposed rule is this:
 years -4001, -801, 2399, 5599 etc. are *not* long. Elsewise the Gregorian rules are applied, 
 e.g. 1899 is *not* long whereas 1999 is.

 The minimum negative value is around (julian) January of year 100. 
 Under MacOS, no date before 1 Jan 1904 can be handled.
-* MILESIAN_YEAR_BASE (Y): the day before the 1 1m of year Y, the "doomsday".
