1999

Doctor Who Universe
Throughout the year, much concern is raised on Earth over a feared computer glitch known as Y2K or the Millennium Bug, which had the potential to cause technological havoc as clocks changed from 1999 to 2000 (the "00" in the date being expected to cause problems for many computer systems). The concern ends up being unfounded, though not without a little help from one, possibly two incarnations of the Doctor. (PDA: Millennium Shock)

May

 * 12 - Adelaide Brooke is born in Finchley, North London. (DW: The Waters of Mars)

December

 * Late December - The Doctor saves Earth from Saraquazel, a being from after the universe, and his servant, Ashley Chapel. (MA: Millennial Rites)
 * 30-31 December - The Doctor, en route to Gallifrey with the remains of the Master, is forced to land the TARDIS in San Francisco and is caught in the crossfire of a gangland shooting. Although his injuries are not life threatening, when doctors discover what appears to be a heart malfunction, Dr. Grace Holloway conducts heart surgery meant to save him; instead, the Doctor "dies" on the operating table. Meanwhile, the Master, manifesting himself as a ghost-like snake, escapes the TARDIS and hitches a ride with Bruce, the paramedic who helped the Doctor. (DW: Doctor Who)
 * 31 - Not long after midnight, the Doctor's body arrives in the morgue and is put into the refrigeration unit. Several hours later - a delay caused by the anaesthetic - the Doctor finally regenerates into his eighth incarnation and escapes (frightening an orderly who is watching the 1931 film Frankenstein on TV). Due to the anaesthetic, the Doctor suffers temporary amnesia. Meanwhile, the Master kills Bruce and takes over the human's body; he subsequently kills Bruce's wife, Miranda, too.
 * During the course of this day, the Master launches a scheme to obtain the Doctor's remaining regenerations. He infiltrates the Doctor's TARDIS with the help of Chang Lee and attempts to use the Eye of Harmony to this end, even though it will destroy Earth. The Doctor and Grace Holloway race to stop him; during this time the Doctor regains his memory and the two share a brief romantic connection. (DW: Doctor Who)
 * Meanwhile, natural phenomenon are reported in the San Francisco Bay area, including unusual tides, flood warnings. Meanwhile, snow is reported in Hawaii. Scientists link this to fluctuations in Earth's gravitational pull that occur only once every 1,000 years (though the real reason involves The Master opening the Eye of Harmony). (DW: Doctor Who)
 * During the battle with the Master, both Grace Holloway and Chang Lee are killed, but the Doctor is able to bring them back to life by reversing time. (DW: Doctor Who)
 * To ring in the New Year, the Institute for Technological Advancement and Research in San Francisco establishes San Francisco Mean Time by unveiling the world's most accurate atomic clock. The Doctor and Grace Holloway crash (and disrupt) the party in order to obtain components needed to defeat the Master. (DW: Doctor Who)
 * The Doctor invites Grace Holloway to travel with him; she declines. (DW: Doctor Who)
 * Other events on 31 December
 * The Doctor and Mel crash a party hosted by the Auton Alisha Hammerson, and defeat another invasion by the Nestene Consciousness. (DWM: Plastic Millennium)
 * The Doctor also stops the millennium bug (probably with a little help from his sixth incarnation) just as the New Year arrives. (PDA: Millennium Shock)
 * While Jack Harkness fights a "Millennium Bug" of his own, Alex Hopkins kills the rest of his Torchwood Three team, then kills himself after Jack returns, just as the New Year arrives. Harkness subsequently takes over Torchwood Three (TW: Fragments)
 * Dave Young spent the entire evening trying to convince his girlfriend, Anji Kapoor, that the millennium wouldn't actually begin for another year. Kapoor, for her part, thought this extreme pedantry meant their relationship was in trouble.  This incident would lead to her insisting on New Year's Eve 2000 that the two of them spend 2001 doing "Wild and Spontaneous Things' — the result of which was the couple spontaneously going to Belgium in February 2001.  There, she met the Doctor and began travelling with him.    (EDA: Escape Velocity)
 * Due to time zone differences, the above events technically occurred hours prior to the incident in San Francisco.

Behind the Scenes
References in the Doctor Who Universe tend to indicate the year 2000 of the start of the millennium, rather than 2001, the technical start of that millennium.

July

 * BFA: The Sirens of Time, a multi-Doctor story co-starring Peter Davison, Colin Baker and Sylvester McCoy, is released on cassette tape and CD. This audio drama is the first release by Big Finish Productions under its new licence with the BBC, allowing them to produce officially sanctioned audio productions featuring concepts and cast members from Doctor Who (Big Finish had already released audio dramas featuring Bernice Summerfield.) The Big Finish line would prosper over the next decade and help fill the void left by the lack of a television series prior to 2005, and would continue even after the series returned. In 2001, Big Finish will score a coup by launching a long-running series of productions featuring then-current Eighth Doctor, Paul McGann.
