Is it not really: the twelfth day of December in the year of two thousand and twelve, Anno Domini (A.D.)? and seeing there was no year zero in this scheme, (for the year AD 1 immediately follows the year 1 BC), sooooooooo technically it is: the twelfth day of December in the year of two thousand and eleven, anno domini? but then; what if the Anno Domini is wrong?
and anyways? that is according to YOUR Julian/Gregorian Calendar -- how archaic?
