A Proposed Usage of 'Common Era' (CE)

Dear Calendar People

Peter Meyer of Hermetic Systems http://www.hermetic.ch/index.php who is also an occasional member of this list uses the Common Era (CE) year numbering system in a specific way, which distinguishes it from AD/BC and may encourage use of astronomical year numbering along with the proleptic Gregorian calendar. In this specific way,

(1)     Common Era (CE) is used only with astronomical year numbering, which has year 1 preceded by year 0 and negative numbered years. There is no BCE.

(2)     Whenever a date is used with a common era year number,  it is always in the (proleptic) Gregorian calendar. Dates before the adoption of the Gregorian calendar are always expressed as though the Gregorian calendar were already in use rather than in the Julian calendar.

The calendar resulting from this is called the Common Era Calendar (rather than Proleptic Gregorian Calendar with Astronomical Year Numbering in Common Era).

Comments from calendar people are welcome.

See http://www.hermetic.ch/cal_stud/astronomical_year_numbering.htm for more details.
