Except that it would be a pure duplication of existing work:

`--gregorian-reform=1582|1700|1752|1753|ARGUMENT'
     Set the period which was skipped during the Gregorian Reformation.
     By default, Gcal runs in the "hybrid" calendar mode, i.e. Gcal
     automatically changes from the Julian calendar system to the
     Gregorian calendar system if output is related to dates after the
     Gregorian Reformation has happened.  *Note Aspects in
     Internationalization: Internationalization, for more details.
     Actually, four fixed default periods are supported, and that of
     the year 1582, of the year 1700, of the year 1752 and of the year
     1753.
...
  Because Gcal as calendar program must also comply the specifics of a
used native language concerning the ordering of day, month and year
(and further things) of a displayed date, the period of Gregorian
Reformation, the type of week number and the representation of calendar
sheets, these criteria are likewise bound to the language code(3)
(*note Internationalization-Footnote-3::).

Bloody pendantic computer scientists, eh? :-)
