Millennium

A millennium (plural millennia) was a period of time equal to one thousand years.

There were differing opinions as to whether the year 2000 or 2001 was the start of the 3rd millennium. It would seem that 2000 was — as evidenced by statements by American news outlets and world-renowned chronologist, Professor Wagg — the start of the 3rd millennium. (DW: Doctor Who) This view was shared by at least one incarnation of the Doctor. (DWN: Doctor Who - The Novel of the Film) Despite the predilection of most humans to celebrate it as the beginning of the millennium, however, at least one other incarnation of the Doctor regarded it as the final year of the 2nd millennium. (MA: Millennial Rites) This tug-of-war between pedantic and common conception of the year was reflected in an argument had between Anji Kapoor and her boyfriend Dave Young. He held fast to the technically correct view that 1st January 2001 was the beginning of the millennium, whereas she found this an example of why she was seriously considering leaving him.
