2000

The year 2000 was, as evidenced by statements by American news outlets and world-renowned chronologist Professor Wagg — the start of the third millennium. (TV: Doctor Who) This view was shared by at least one incarnation of the Doctor. (PROSE: 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 technical and common conceptions of the year was reflected in an argument between Anji Kapoor and her boyfriend Dave Young. He held fast to the view that 1 January 2001 was the beginning of the millennium, whereas she found this pedantry a reason to seriously consider leaving him. (PROSE: Escape Velocity)

According to one account, Zoe Heriot originated from 2000. (AUDIO: Prison in Space) Despite the fact that most sources date Zoe's life to a much later time, no source disputes that she was a fan of the Karkus comics published in the Hourly Telepress in this year. (TV: The Mind Robber, PROSE: The Wheel of Ice)

Behind the scenes

 * References in the Doctor Who universe tend to indicate the year 2000 was the start of the millennium, rather than 2001, the technical start of that century.
 * Doctor Who and the Tenth Planet directly contradicts The Tenth Planet, the television story the novelisation is adapted from. The 1976 novelisation considers the First Doctor's regeneration having taken place in 2000, rather the 1986 placement the 1966 television story gave.
