2009

January - March

 * Dr. Owen Harper, who continued to have difficulty accepting his new undead existence, was relieved of his duties with Torchwood Three (though he continued to help out as their new tea boy) as Martha Jones agreed to stay on as medical officer. After a fruitless suicide attempt, Harper began to come to terms with his death and returned to active duty for a mission to retrieve an alien artefact from a dying millionaire, Henry Parker, who revealed intimate knowledge about Torchwood and its personnel before his passed away. With Owen Harper reinstated, Martha departed Torchwood to return to her duties at UNIT. Soon after, Owen successfully talked a young woman out of committing suicide. (TW: A Day in the Death)
 * On the night of her bachelorette party, Gwen Cooper was made the host of Nostrovite offspring, whose mother was waiting to pull it straight out of Gwen's womb. At her and Rhys Williams' wedding venue, Rhys destroyed the unborn Nostrovite young (without letting Gwen come to harm) with the Singularity scalpel, and Jack Harkness destroyed the mother. Gwen married Rhys. (TW: Something Borrowed)
 * The Torchwood Three team investigated the Night Travellers, and defeated them by trapping their celluloid forms on film and exposing the film. (TW: From Out of the Rain)
 * Gwen Cooper investigated the disappearance of Jonah Bevan and others who were lost through the Cardiff Rift and discovered Flat Holm Island, where some of those apparently returned by the Rift were kept. Nikki Bevan met her son, who had only vanished seven months previously, at a much older age and she was forced to leave Jonah behind at Flat Holm, after hearing an unearthly shriek come from him. (TW: Adrift)

March

 * Captain John Hart placed bombs in an abandoned building where the Torchwood team, except for Gwen, were investigating. After they escaped, John showed Jack a hologram of Gray. (TW: Fragments)
 * After regaining consciousness the Torchwood team tried to stop John Hart. Later that night a series of alien attacks occurred in Cardiff, including Weevils killing four senior Cardiff police officers, a Hoix let lose in a hospital where it was captured by Owen Harper, a group of men in cloaks haunting a building only to be shot dead by Toshiko Sato and Ianto Jones. John Hart captured Jack Harkness and set off several bombs in buildings in key locations across Cardiff. It was then revealed Jack's brother Gray was forcing John Hart to do his bidding. Gray sent Jack back to 27 A.D. to be buried, but Jack was discovered in 1901 and stored in Torchwood's cryo-chamber to be re-awakened. Gray unleashed all of the Weevils in the sewers on Cardiff, shot Toshiko, who later died of her wounds, and Owen was disintegrated by nuclear radiation after the radiation flooded into the room he was in, saving Cardiff. (TW: Exit Wounds)

Spring, Prior to Easter

 * Martha Jones called in the surviving members of Torchwood Three for their help with an incident at CERN. (BBCR: Lost Souls)
 * By this time, conspiracy theorists had begun noting the disappearance of bees from the planet Earth, which was also noted by Donna Noble. (DW: Partners in Crime, et al) It was later discovered that they left Earth in anticipation of its imminent relocation to the Medusa Cascade. (DW: The Stolen Earth)
 * Donna Noble investigated Adipose Industries, reuniting with the Tenth Doctor in doing so. Matron Cofelia caused the forced birth of thousands of Adipose inside Londoners' bodies. The Doctor and Donna shut down the parthenogenesis signal before it proved fatal. The Adipose were sent up into their ship, and Cofelia was killed by the Adipose First Family to cover up evidence of the Family seeding on a Level 5 planet. Donna then joined the Doctor in the TARDIS. Before leaving with the Doctor, however, Donna briefly encountered Rose Tyler (unaware of Rose's identity). (DW: Partners in Crime)
 * UNIT investigated the simultaneous deaths of 52 people at the same time in people across the world, all in ATMOS-equipped vehicles. Dr. Martha Jones, now working for UNIT and engaged to Tom Milligan, called in the Tenth Doctor for assistance. UNIT raided an ATMOS factoy. The Sontarans captured Martha and cloned her. As part of a Sontaran invasion plan, all ATMOS-equipped vehicles, one half of all cars on Earth, began emitting a toxic gas. (DW: The Sontaran Stratagem)
 * The TARDIS, with Donna Noble inside, was taken into the Sontaran flagship. The Sontarans invaded the ATMOS factory, but UNIT eventually took it back, with the Doctor finding Martha with the help of her clone. The clone Martha's link was severed, revealing the ATMOS gas would be used to clone more Sontarans before she died. With the help of Donna, the Doctor stole his TARDIS back and used the technology from the Rattigan Academy to create an Atmospheric Converter to destroy the gas. Luke Rattigan, learning that his plans to start a new world with his students had failed, swapped places Doctor's place in destroying the Sontaran fleet, taking him with them. The TARDIS, with Martha inside as well as the Doctor and Donna, suddenly started moving on its own. (DW: The Poison Sky)
 * Returning from an unexpected trip to Messaline in 6012, Martha Jones continued with her own life on Earth. (DW: The Doctor's Daughter)
 * The Earth and 23 other missing planets were relocated to the Medusa Cascade by the Daleks (with three further planets, Adipose 3, Pyrovillia and the Lost Moon of Poosh being taken from other time zones) under the control of the Supreme Dalek and Davros. The Tenth Doctor went to the Shadow Proclamation and tracked the Earth to the Medusa Cascade before the trail went cold. An invasion of Earth by the Daleks commenced and a number of humans were taken away to the Crucible. The current British Prime Minister was shot down by Daleks. As part of a counter-insurgency against the Dalek invasion, former Prime Minister Harriet Jones brought together a number of the Doctor's former companions, including Captain Jack Harkness, Sarah Jane Smith, and Martha Jones in order to contact the Tenth Doctor using the Cardiff Rift and Mr Smith, and before she herself was killed by the Daleks. Rose Tyler, meanwhile, contacted Donna Noble's family and was ultimately reunited with the Doctor, having broken through to the out-of-sync Cascade. As well as this, Maria Jackson and her father were in Cornwall and safe from Daleks. (DW: The Stolen Earth)
 * Shortly after being reunited with Rose, the Tenth Doctor underwent a partial regeneration in order to repair damage from a Dalek blast, throwing his regenerative energy into his old hand. The TARDIS was taken to the Crucible, where humans were being tested for the reality bomb. The TARDIS was almost destroyed in the Crucible's Z-neutrino core, but the energy-infused hand formed into a human Time-Lord Meta-Crisis clone of the Doctor after making physical contact with Donna Noble, safely piloting the TARDIS away. Sarah Jane threatened the Crucible with a warp star, while Martha planned to blow up Earth, stopping the use of the reality bombs. Davros quickly stopped them. The Meta-Crisis Doctor and the Donna attempted an attack on Davros but failed; the electricity from his hand awakening the dormant Time Lord mind, the regeneration energy from earlier having spread both ways, turning her into the DoctorDonna. Donna used a Dalek interface to shut down the Crucible and disable the Daleks and was able to send 26 of the 27 planets back home, while the Meta-Crisis Doctor finished off the Daleks. The Doctor and his companions towed the remaining planet, Earth, home with the TARDIS; this sparked worldwide celebrations around the planet. Afterwards, Mickey Smith chose to remain on his original Earth instead of returning to Pete's World, Jack and Martha went back to their respective jobs, and the Doctor returned Rose and Jackie Tyler to Pete's World, along with his clone, which the Doctor considered unsafe and asked Rose to help the clone. Donna Noble was returned to her family, but with all memories of the Doctor wiped from her mind due to the danger to her survival posed by her transformation. (DW: Journey's End)
 * At some point during these events, a young girl named Adelaide Brooke lost her family and encounters a Dalek that, for reasons unknown to her, chose not to exterminate her. This event inspired her to become an astronaut, becoming a trailblazer for human exploration of space - in her case, establishing the first human base on Mars in 2058 and, in turn, inspiring generations of Brookes who would further expand humanity to reach into the stars. (DW: The Waters of Mars)
 * In the aftermath of the Medusa Cascade incident, the human race on Earth began coming to terms with the fact it was not alone in the universe. While many accepted it, others experienced crises of faith and a large number of people committed suicide. Brian Green became British Prime Minister sometime before September. (TW: Children of Earth: Day One)

Spring or Summer

 * The last survivor of the ATMOS Sontaran invasion, Commander Kaagh, attempted to destroy Earth by commandeering the Tycho Project in Goblin's Copse, landing satellites onto nuclear stockpiles, but was thwarted when Luke Smith shut down the project, and Chrissie Jackson attacked Kaagh's probic vent, knocking him out. Kaagh left Earth disgraced. Chrissie Jackson became aware of aliens and of Sarah Jane and her team's fight against them. (SJA: The Last Sontaran, at least 6 weeks before the events of The Day of the Clown)

April

 * 12: Easter. The 200 bus travelled through a wormhole, leaving several passengers, including the Tenth Doctor and Lady Christina de Souza stranded on the desert planet of San Helios, which had been turned into a sandy wasteland within the previous year by alien stingrays that had started approaching the wormhole to devour Earth. Utilising some Tritovore anti-gravity clamps taken by Lady Christina, the 200 was able to fly through the wormhole safely. The wormhole was closed and the handful of stingrays that made it through were destroyed by UNIT soldiers. The Doctor declined Lady Christina's offer to join the TARDIS, but allowed her to evade arrest. (DW: Planet of the Dead)

May

 * 12 - Adelaide Brooke's 10th birthday. (birthdate seen in DW: The Waters of Mars)
 * 15 - 18 - the Mandragora Helix attempted a takeover of Earth through the MorganTech computer systems. (NSA: Beautiful Chaos)

Summer
The following take place after 23rd June.
 * Maria and Alan Jackson moved to America. (SJA: The Last Sontaran)
 * Rani Chandra and her family moved to Bannerman Road. Being stalked by a clown, Clyde and Rani investigated Spellman's Magical Museum of the Circus. The owner, Elijah Spellman, was revealed to be both the clown and the Pied Piper, having come from a meteorite in the Jeggorabax Cluster centuries before. The Piper gathered children he had given balloons to, but Mr Smith interfered by contacting their mobile phones. Clyde, weakening the fear-eating Pied Piper with humour, allowed Sarah Jane to trap the Piped Piper back inside his meteorite, releasing the children who had been recently taken by him. (SJA: The Day of the Clown)
 * Martin Trueman, using the power of the Ancient Lights, beings from the Pre-Universe, started enslaving every human on Earth using astrology. Luke, not having a starsign, broke this connection. (SJA: Secrets of the Stars)
 * Rani Chandra discovered the Berserker Pendant and Clyde Langer's father Paul came to visit him after walking out on his family years before. Paul pocketed and was possessed by the pendant, but Sarah Jane and the team managed to bring him back to himself and Clyde threw the pendant into the sea. (SJA: The Mark of the Berserker)
 * The Trickster used a time fissure to trick Sarah Jane into saving her parents' lives in 1951 and created an alternate timeline where he drained the life out of Earth and enslaved humanity. Sarah Jane and her young friends returned to 2009 after Sarah Jane's parents, Eddie and Barbara Smith, prevented this alternate timeline by sacrificing themselves in 1951. (SJA: The Temptation of Sarah Jane Smith)
 * Mrs Wormwood and Commander Kaagh became allies in the light of Wormwood's exile from the Bane and Kaagh's self-imposed exile in disgrace from the Sontarans. Taking the Tunguska Scroll from Sarah Jane and her gang, they used Luke to place the scroll on the "tomb" of Horath, the tyrant of the Dark Empire, in an attempt to bring him back. Kaagh, disgraced by Wormwood's preference over her "son", Luke, pushed Wormwood into the interdimensional portal that contained Horath, destroying the link. (SJA: Enemy of the Bane)
 * The Veil Androvax crash-landed in Ealing, followed by the Judoon Tybo. Androvax escaped into Genetec Systems, using Nanoforms to build a spaceship and destroy Earth. Luke deactivated the Nanoforms, and Tybo arrested Androvax. For their interference, Clyde and Rani were grounded to Earth by the Judoon. (SJA: Prisoner of the Judoon)
 * Rani was called to Danemouth by Samuel Lloyd to investigate the haunted funfair, with Sarah Jane, Luke and Clyde following. Rani found the alien Eve, whose powers had become out of control. With Eve taken to Ship to control them, Sarah Jane gave Ship the co-ordinates to the black hole K9 was protecting, freeing him and powering up Ship. Eve, Samuel and Eve's adopted father Harry left in Ship to explore the universe. (SJA: The Mad Woman in the Attic)
 * Peter Dalton was about to marry Sarah Jane Smith, but the Tenth Doctor interfered. The Trickster took Sarah Jane and her gang into a time loop, with Sarah Jane and Peter stuck in one second and the Doctor, Clyde and Rani in another. Peter refused his deal with the Trickster and he died. Time resumed its natural course and with Peter nowhere to be seen, Sarah Jane called the wedding off. (SJA: The Wedding of Sarah Jane Smith)

Summer - Autumn
The following takes place after the events of SJA: The Wedding of Sarah Jane Smith.
 * A half-alien, half-human girl named Freda was sent back from the future to escape persecution and came under the protection of Torchwood Three. (BBCR: Asylum)
 * Torchwood Three discovered that Torchwood India still existed and that its members were preserving their own time in their headquarters by draining the life out of masses of innocent civilians, with plans to roll back time to Britain's Golden Age across the world. Torchwood Three defeated them and Torchwood India was frozen in time. (BBCR: Golden Age)
 * Torchwood Three combatted a mysterious force that puts people into coma-like trances after they answered the phone. (BBCR: The Dead Line)
 * Rhys Williams' uncle Bryn died and Torchwood Three investigated mysterious power cuts and Miss Carew, a woman in her eighties that was fit and at work after being on her deathbed not too long before. Carew worked with the being called Fitzroy to destroy all electricity on Earth, but was stopped. (BBCR: The Devil and Miss Carew)
 * Torchwood Three, working in cooperation with UNIT, tracked a distress signal to the Mariana Trench and discovered Sam Doyle of the Guernica underwater who hadn't aged in fifty years. The team defeated the entity possessing him that later entered Carlie Roberts. (BBCR: Submission)
 * At Ashen Hill Manor, Sarah Jane discovered the people who had disappeared at the manor had been trapped inside another dimension, keeping Erasmus Darkening alive. Sarah Jane defeated Erasmus Darkening, tricking him by putting him into an electromagnetic field. (SJA: The Eternity Trap)
 * The Mona Lisa was in the International Gallery in London, on loan from the Louvre. Due to her proximity to The Abomination, which was made from the same sentient paint the Mona Lisa was made out of, Mona Lisa was brought to life. She returned to her painting when she was tricked into bringing a sketch of K9 to life with her powers, who shot at The Abomination. (SJA: Mona Lisa's Revenge)
 * The Slitheen-Blathereen family (acting as Blathereen) captured some Slitheen, stopping them from destroying the Earth. The Slitheen-Blathereen handed Sarah Jane a Rakweed plant, which the following day mutated, sending spores across London that would have put humans into a coma. Mr Smith used a high-pitched frequency across the city to destroy the plants, and when the Slitheen-Blathereen attacked Sarah Jane, he did so again, destroying the Rakweed-saturated bodies. (SJA: The Gift)

September

 * Every child on Earth stopped in their tracks and began reciting the message "We are coming" repeatedly, all them in English. Behind the scenes, the British government stated that this came from the 456, a race that had visited Earth before. Gwen Cooper spoke to Clement MacDonald, who also stopped and said the message and told Gwen about how when he was a child, the children on his orphanage bus were stolen away, with him almost being taken too. Jack Harkness had a bomb encased in his body, which blew up the Torchwood Three hub. (TW: Children of Earth: Day One)
 * Jack, his body slowly reconstituting himself, was held by Johnson, while Gwen went on the run from being assassinated by the British government, revealing to her husband Rhys that she became pregnant. The children on Earth stopped again to say "we are coming...tomorrow". Mr Dekker built a container for the 456 built to specification filled with unusual gases. Lois Habiba revealed to Gwen that John Frobisher was behind the death orders for Torchwood. Johnson sealed Jack in concrete, but Ianto arrived, releasing him. Jack and Ianto escaped with Rhys and Gwen. (TW: Children of Earth: Day Two)
 * The 456 Ambassador materialised in the gassy container in Thames House. They demanded 10% of all of Earth's children. Clem revealed that Jack was behind the handovers back in 1965, and Jack stated that it was for the 456. (TW: Children of Earth: Day Three)
 * Jack continued to talk about what happened the night he and others targeted by the British government in the present handed children over to the 456 in 1965. At Thames House, the 456 Ambassador was seen to have one of the children of 1965 as part of its system, unaging. As negotiations failed, the government started to think of ways to hand over the 10%, which Lois recorded with Torchwood's Eye-5 contact lenses as incriminating evidence. The 456 killed Clem. Jack and Ianto faced the 456, but were also killed, along with the rest of Thames House once the 456 released the virus. Jack revived, upset over his loss. (TW: Children of Earth: Day Four)
 * The British government started sending the 10% to the 456, disguising it as "inocculations". The Ambassador revealed that the children were to be used as drugs. Unable to cope with this, Frobisher killed his family and committed suicide. Gwen and Rhys tried to escape with as many children as they could. Jack used the wave that the 456 used to kill Clem the previous day to destroy the 456, but was forced to sacrifice his grandson Steven to set it up. Stricken with guilt over the death of his grandson, Jack left Cardiff and spent the next few months wandering the Earth. (TW: Children of Earth: Day Five)
 * Children of Earth dates based upon on-screen evidence, specifically a newspaper headline.


 * Sarah Jane, Luke, Clyde and Rani fought and killed a Raxacoricofallapatorian, while K9 defused a bomb. (SJA: The Nightmare Man)

December

 * 24 - The Master was resurrected by Miss Trefusis and the new governor of Broadfell Prison on Christmas Eve. Lucy Saxon interfered with the resurrection, causing an explosion at the prison and killing everyone inside, except for the Master. The White House announced that President Barack Obama would make a Christmas Day speech announcing new economic initiatives aimed at resolving the current worldwide economic crisis. (DW: The End of Time)
 * 25 - The Master was captured by soldiers working for Joshua Naismith so that the Master could help him use the Immortality Gate. However, the Master betrayed him and as Barack Obama gave a speech on the Recession, used the Gate's abilities, intended to heal planets, to turn every single human on Earth except for Donna Noble into copies of the Master.
 * 26 - During this time a diamond called a White-Point Star was sent from Gallifrey through time and space and crashed to Earth where it was retrieved by the Master, who used it to open a portal that allowed Rassilon and other Time Lords to escape the Last Great Time War. Rassilon undid the "cloning" of the Master and Gallifrey started entering the space around Earth, with the Time Lords ready to end time. The Tenth Doctor shot the diamond, breaking the connection and the Master blasted the Time Lords back into the time lock, the Master also disappearing. The Tenth Doctor rescued Wilf from certain death, but by doing so, the Doctor was flooded with radiation from the booth he was in. The Doctor gradually began his regeneration cycle. A malfunction with the world's wi-fi systems was later blamed for causing mass hallucinations, a cover story concocted by Mr Smith. Shortly after, Luke Smith was nearly run over by a car on Bannerman Road, but was rescued by the slowly-regenerating Tenth Doctor, who disappeared into his TARDIS. (DW: The End of Time)

 * Spring or Summer - The Master ruled Earth with an iron fist. During this time, the Tenth Doctor, physically aged, was kept captive aboard the UNIT airship the Valiant, along with Jack Harkness and most of Martha Jones' family. Meanwhile, Martha, following instruction given to her by the Doctor, spent the year travelling the world spreading stories and faith about the Doctor. Ultimately, the collected faith of the people of the world restored the Doctor, leading to the Master's defeat. Captain Jack destroyed the Paradox machine, reversing time back to 2008. (DW: Last of the Time Lords)

Donna's World

 * Prior to Easter - After the Titanic fell to Earth on 25th December 2008, annihilating London and rendering most of southern England unliveable with nuclear radiation, Great Britain had become a police state.

 * Spring, Prior to Easter - After Donna's family was relocated, the parthenogenesis of the Adipose was a huge success, with 60 million Americans killed before the Adipose were moved to their spaceship. Gwen Cooper and Ianto Jones died saving the world from ATMOS, and Jack was transferred to Sontar. Rose Tyler worked with the UNIT of this timeline to help Donna Noble restore the proper chain of events which, at one point, involved sending Donna back to 2007. (DW: Turn Left)

Other timelines

 * Summer, after 23rd June - Rani, feeling upset about her not living up to the standards of her predecessor Maria, offhandedly wished that her friends leave her alone. Ship took this as an actual request, and erased Sarah Jane, Luke, Clyde and K9. This was undone when Eve's son Adam reversed this once an older Rani told him about this in 2059.
