Annex A Registration of 34300 requires in A.3: Basic eligibility for a calendar system to be assigned a calendar system code is one of: — The system has been approved for official use at some level of government (current or historic); — The system has had significant use in history; — The system is in current use.

Hence the forerunner "Julian calendar system" of the "Gregorian" one should be treated at least as a "historic civil time", not "Orthodox Christian", only.

A furthere motivation for this proposal is found in

Brockhaus Enzyklopaedie with 20 volumes vol 9 from 1970, which contains on pp.625-629 an article "Kalender" with sections on ancient culures, european calendar reforms:

In Egypt the aim of aligning the year to the seasons was reached in 238 BC by the decree of Kanupus, which arranged every 4th year a leap year. It was included into the Julian calendar introduced by Julius Caesar 46 BC for the Roman Empire, remaining in force for many centuries.

In the Gregorian calendar, introduced by Pontifex Gregory on 15 October 1582, the number of leap years was decreased: the [then forthcoming] centennial years, 1600, 1700, … are leap years, only, if their centennial numbers 16, 17, … are divisible by 4. The years 1600 and 2000 where thus leap years.

Initially, the new calendar was accepted by the Catholic states, later by the protestant states, but not by the orthodox states (which continued to use the Julian calendar), and by Russia after the revolution in February 1918.
