When did the millennium officially begin? January 1, 2001 (conventional
wisdom)
The new millennium must
necessarily begin after the previous one thousand year period has been
completed.
Many people, being
confused by the millennium bug news, think that the millennium change coincides
with the moment that 1999 becomes 2000. Others who think a little further assume
that our calander started with the year zero.
But, how disappointing for
them, the modern calendar did not start with a year zero.
Credit for the modern
calendar is given to a sixth-century monk named Dionysius Exiguss (Dennis the
Short) who was commissioned by Pope St. John I to create a chronology of time.
Dionysius estimated Christ's birth at 753 A.U.C. (from the founding of Rome),
and then restarted time beginning with the year of Christ's birth as Year 1 A.D.
(A.D. stands for "anno domini" or "the year of our lord").
Indeed, when Dionysius created this new numbering of time, the whole concept of
a zero did not even exist.
Accordingly, since we
started with year 1, the first year will be completed at the end of year 1, the
first century at the end of A.D. 100, the first millennium at A.D. 1000, and the
second millennium at the end of A.D. 2000. By this logic, as of January 1, 2001,
we will have completed exactly two thousand years and will be ready to enter the
third millennium.
This is the conventional
view which has been backed by the Library of Congress and the National Bureau of
Stands and Technology. Similarly, the Royal Greenwich Observatory in Cambridge,
England has decreed that the first day of the third millennium falls on
