2006

Before 6 March

 * Owen Harper encountered Jack Harkness again at Katie Russell's graveside and was recruited by him as Torchwood Three's medical officer. (TW: Fragments)

March

 * 6 - The Ninth Doctor returned Rose Tyler to her home in London. Due to a miscalculation they arrived a year late. Rose learnt she was believed murdered and Mickey Smith had been a suspect.

Big Ben was side-swiped by a UFO which crashed into the Thames. (DW: Aliens of London) Many people witnessed the crash, including Elton Pope, (DW: Love & Monsters) but the crash was later covered up as a hoax. (WEB: whoisdoctorwho.co.uk) An "alien astronaut" from the UFO was taken to Albion Hospital, where the Doctor and Toshiko Sato examined it. "Doctor" Sato was working undercover for Torchwood Three, covering for Owen Harper, who was hungover on his first week working for Torchwood. (DW: Aliens of London, TW: Exit Wounds) Most of the Earth's leading experts on aliens were killed, as was the Prime Minister of Great Britain. (DW: Aliens of London)

10 Downing Street was destroyed by a Harpoon missile targeted by Mickey Smith. The fortitude of backbench MP Harriet Jones during this crisis contributed to her ascent to power and the post of Prime Minister. Mickey Smith, now webmaster of the "Who is Doctor Who?" website, was asked by the Doctor to install a virus that would wipe out all references to him on the Internet. (DW: World War Three) Mickey did not do this. Instead he renamed his website Defending the Earth! and proceeded to chronicle unexplained happenings, usually involving the Doctor. (WEB: whoisdoctorwho.co.uk)

June

 * The Tenth Doctor visited St. Nicholas's Hospital, taking on the alias of a consultant. (Times Online: Deep and Dreamless Sleep)
 * 25 - Edward Grainger died on his hundredth birthday. (ST: Forgotten)

July

 * 20 - After reading an internet article about Jo Jones, Polly Wright emailed Brigadier Lethbridge-Stewart and they shared stories of their adventures with the Doctor. (CC: The Three Companions)

September

 * The RaxacoricofallapatorianBlon Fel-Fotch Passameer-Day Slitheen, posing as the human Margaret Blain, mayor of Cardiff, plotted to blow up the Earth with the Blaidd Drwg nuclear power plant and the Cardiff Rift. This would let her escape on her extrapolator. The Ninth Doctor, Rose Tyler, Mickey Smith and Jack Harkness captured her, but she used a fallback plan to make the extrapolator latch onto the TARDIS' energies (having been parked directly on the Rift) and still destroy Earth. The plan backfired and the Heart of the TARDIS opened up, regressing Blon to an egg. The Doctor and his companions returned Blon to Raxacoricofallapatorius to start a new life. (DW: Boom Town) At this moment there were no fewer than three versions of Harkness in Cardiff at different points in his timeline: the Jack travelling with the Doctor, an older Jack now operating Torchwood Three while keeping himself and his team in the Hub during these events (TWN: The Twilight Streets) and a still older Jack in cryogenic freeze in the Torchwood vaults, unknown to the Torchwood Three team. (TW: Exit Wounds)

October

 * Idris Hopper recognised Jack Harkness and chased him. Seeing past its perception filter, he witnessed the invisible lift in action. An attempt to erase Idris' memories with retcon in his dinner failed and Idris became angry with Jack because he thought he was poisoned. (TWN: The Twilight Streets)


 * 31 - The British Rocket Group space probe Guinevere One launched from Earth for a scheduled rendezvous with Mars on Christmas Day. (Date: WEB: http://www.guinevere.org.uk/)

November

 * 23 - Retired Torchwood agent Lucia Moretti, a former lover of Jack Harkness and mother of his daughter, passed away due to heart disease.

December

 * 24 - The Tenth Doctor recovered from his regeneration at the Powell Estate. Sycorax intercepted Guinevere One and sent a threatening message to Earth. The Sycorax ship's pilot fish landed. The Doctor stopped them from taking his regeneration energy. Prime Minister Harriet Jones sought help from UNIT as the Doctor was still in bed. (DW: The Christmas Invasion)
 * 24 - Daniel Thompson, age four, was struck by a vehicle and hospitalised at St. Nicholas's Hospital in London. The Doctor, in his tenth incarnation, only older than his encounter with the Sycorax, shared an adventure with Daniel and spent time at St. Nicholas's Hospital waiting for Daniel to recover. (Times Online: Deep and Dreamless Sleep)
 * This meant there were two versions of the Tenth Doctor in London at the same time.


 * 25 - The Sycorax ship entered London airspace at around 0745. (DW: The Christmas Invasion, Love & Monsters) Elton Pope gazed up at the ship in awe. (DW: Love & Monsters) Sarah Jane Smith wondered if the ship had the Doctor onboard, taking care of the situation. (DW: School Reunion) Donna Noble, however, was oblivious to events due to a hangover. (DW: The Runaway Bride) The Sycorax used blood control on one third of Earth's population. Harriet Jones appeared on television to ask for the Doctor's help. The Doctor defeated the Sycorax leader, who was later killed after trying to sneak-attack the Doctor. In the battle the leader cut off the Doctor's hand, which grew back. The Torchwood Institute destroyed the retreating Sycorax ship at Harriet Jones' orders. The Doctor regarded this as murder and engineered Jones' spiral in the polls. Although the Earth had been visited and even invaded many times before by alien races, the Doctor told Rose the Sycorax event marked the first occasion that life beyond Earth became common knowledge, and that Earth itself was now becoming noticed by other worlds. (DW: The Christmas Invasion) This sentiment was later echoed by Jack Harkness in his statement, "The 21st century is when it all changes." (DW: Last of the Time Lords and repeatedly in Torchwood)


 * Later, Jack Harkness found and retrieved the Doctor's hand, which ended up at Torchwood Three. (TW: Everything Changes et al, DW: Utopia)


 * Ursula Blake snapped a photo of the Tenth Doctor celebrating with Rose Tyler in London. Meanwhile, on the Internet, there began frantic speculation among conspiracy theorists as to what had really happened during the Sycorax invasion. (DW: Love & Monsters)


 * Later, Ursula posted the photo to her blog. (DW: Love & Monsters)

 * Mickey helped Rose to get back to the Ninth Doctor by connecting a truck to the Heart of the TARDIS to open it. In doing so, Rose allowed the Heart to get inside her head and pilot her to the Game Station in 200,100. (DW: The Parting of the Ways)
 * After March, but before December: Harriet Jones was elected British Prime Minister. (DW: The Christmas Invasion)
 * Former teacher Oswald Danes was convicted of the rape and murder of twelve year old Susie Cabina. (TW: The New World)

Early 2006

 * According to his book, The Writer's Tale, Russell T Davies, David Tennant and others involved in Doctor Who, following production of DW: Doomsday, agreed that after the fourth series the program would be rested for a year, except for the occasional special. This idea evolved into the 2009 Specials season and dovetailed with the eventual departures of Davies and Tennant from the series.

Unknown dates

 * Christopher Eccleston earned a recurring role in the NBC series Heroes. While Eccleston wasn't the first to get a role on American TV after his tenure as the Doctor (he was preceded by Tom Baker, Peter Davison and Colin Baker in this regard), he was the first to gain a recurring role in an American series. His role as Claude, the Invisible Man, included a reference to the Doctor in that he uttered the catchphrase, "Fantastic!". He also shared several scenes with Eric Roberts, who played the Master in the 1996 TV movie. Eccleston appeared in five episodes broadcast in early 2007.
