2000

The year 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.
