Sorry!! Too Bad !-- About your other point: a pope in the 900 adjusted the calendar and changed the years. Are you advocating we should change the current date to 2008 .Is that your main concern, that we correctly reflect the date of the birth of Christ.
What we've got is close enough for government work...
(1) The Gregorian reform of the calendar took place in the year 1581 of the Julian calendar and the year 1582 of the current Gregorian system.
Not in the 900s. You're off by about 600 years.
(2) One of the reasons why the calendar was adjusted was precisely because of the concern that the inaccuracy of the Julian calendar was falsifying the dating system with regard to Christ's birth.
(3) The date of 4 BC for the actual birth of Christ is a guess by some scholars. It isn't an established fact and a case can be made for the year 1. It would be silly to alter our calendar every time scholars changed their mind about the real dating of the Nativity.
So, in changing the current date to 2008, would it be considered a third term, or would we still be eligible for 4 MORE YEARS!!
Great idea. I could skip 4 years of mortgage payments. ;~))
