2000

The year 2000 was, as evidenced by statements by American news outlets and world-renowned chronologist Professor Wagg — arguably the start of the Third millennium. (TV: Doctor Who) This view was shared by at least one incarnation of the Doctor. (PROSE: 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 Second millennium. (PROSE: Millennial Rites) This tug-of-war between the pedantic and common conceptions of the year was reflected in an argument between Anji Kapoor and her boyfriend Dave Young. He held fast to the technically correct view that 1 January 2001 was the beginning of the millennium, whereas she found this an example of why she was seriously considering leaving him. (PROSE: Escape Velocity)
