Today is a special day - it is the 18th of December 2007 as reckoned by the Julian calendar and there is one week to go until Christmas.
Of course as reckoned according to the Gregorian Calendar it is the 31st of December and therefore the last day of 2007. And since this is the calendar recognized by our civil authorities and the only one known to the majority of us, we will all celebrate the new year tonight and recover tomorrow.
It is long forgotten but the English speaking world used to begin the new year on the 25th of March. The change came in 1751 when Great Britain adopted the Gregorian Calendar, a matter of no import except to historians who if they don't watch themselves can get caught out as to the year in which a particular event occurred if it happened in January, February or March in the years before 1751.
The AD/BC designation for years (or more formally "Anno Domini Nostri Iesu Christi" and "Before Christ") was first devised in the 5th century has been in common use throughout Europe since the 8th. This system has now become a relic from our unsophisticated past. Amongst the enlightened it has been replaced be CE/BCE. CE stands for Common Era or occasionally it is said to stand for Christian Era. It is easy to translate between the two systems, the actual number remains the same, all that is required is to drop the AD from the front and replace it with a CE to the rear. A process the labels on most museum exhibits have already undergone.
The CE/BCE system for designating years may not last long. The ancient city of Oxford, a town that owes its very existence to Christian scholarship, is engulfed in controversy over the ringing of church bells and the imams call to prayer being broadcast through loud speakers from a local mosque.
Who knows how that one will play out but pity the poor museum curators - sometime in the future they are likely to be required to translate all the dates on their exhibits yet again. And translating dates from the Gregorian calender to those of the Islamic lunar calender is a lot more tricky than dropping AD from the front of the number and replacing it with CE to the rear.
To assist Microsoft has produced the Kuwaiti algorithm which can translate Gregorian dates to those of the Hijri (Islamic) calendar, well sort of.
But I wouldn't be at all surprised that even with the software the process produces more headaches than tonights New Years eve over indulgence.

Surprised you are advocating it Andrei. From Wikipedia:
"Common Era notation has been adopted by many non-Christians, and also by some Christians wanting to be sensitive to non-Christians. The use of BCE and CE has been criticized by some who favor the BC/AD system as being "the result of secularization" and "political correctness"."
Are you Psycho Milt in disguise?! ;-)

What makes you think I am advocating the use of CE/BCE over AD/BC Sean?
I guess your internet browser doesn't recognize the "sarcastic tone" tag

Sean, you missed a bit. That quotation from Wikipedia begins "Originating among Christians at least as early as 1617 (at first in Latin), Common Era notation has been adopted by many non-Christians..."
It's 17th Century political correctness gone mad, that's what it is.
If you are going to quote, quote fully. The Wikipedia article is here

Andrei - fair call. Your paragraph was of a factual nature though my browser sarcasm tag did miss the "This system has now become a relic from our unsophisticated past. Amongst the enlightened..." bit.
Paul - I haven't listed Andrei's quote in it's entirety because no point in including the irrelevant bits. I have however included a "..." so it is more clear the quote includes more text. Sorry.

For information purposes CE is obviously redundant serving only to erase Christian anachronisms.
I read Andrei as pointing to the possibility that once you gleefully separate yourself from one cultural heritage, Christianity in this case, you must actively fill the vacuum.
Indifferent consumerism will probably not suffice and Islam will be happy to occupy the space formerly filled by Christianity.

Paul your 17th century PCism
was in fact written as vulgaris aerae or Vulgar Era which might seem apt to a dispassionate observer of this evenings festivities.
So are we about to usher in 2008 VE?
Posted by: andrei | December 31, 2007 at 12:58 PM
Given that "vulgaris aerae" actually does translate to "common era", not "vulgar era", I think CE will do just fine instead.

CE etc is pretty funny. The measurement is still calculated from the (approximate) birth of Jesus the Messiah of the Jews.
Inverse whitewashing! (Blackwashing??)
Happy new year! :-)

Above all, the BC and AD syndrome is an indication of how much power a religion can sew up.
Interesting to know that secular versions of these abbreviations were available as a byproduct of the Enlightenment.

He makes up for advocating it by including some token muslim bashing.
