A number of deaths also occur at a Cardiff hospital as a result of Durac's manifestation. (TW: Dead Man Walking)
 * 02 - Dr. Owen Harper, who continues to have difficulty accepting his new undead existence, is relieved of his duties with Torchwood Three (though he continues to help out as their new tea boy) as Martha Jones agrees to stay on as medical officer.

April

 * Thousands of Adipose are born from peoples fat and walk around the streets. During this time, Donna Noble reunites with the Tenth Doctor and begins her travels with him. Before leaving with the Doctor, however, Donna briefly encounters Rose Tyler (although she is unaware of Rose's identity). (DW: Partners in Crime; Date: NSA: Beautiful Chaos)
 * The Sontarans invade Earth. During this event, Martha Jones is temporarily reunited with the Doctor and meets Donna Noble for the first time. Donna also narrowly misses witnessing a brief transmission from Rose Tyler in the TARDIS. As part of the Sontaran invasion plan, all ATMOS-equipped vehicles begin emitting a toxic gas intended to transform the world's atmosphere into a more hospitible one for Sontaran offspring; numerous fatalities are reported worldwide before the Doctor disables the devices. Afterwards, the ATMOS devices are removed from the planet's vehicles. (DW: The Sontaran Stratagem/The Poison Sky; Date: NSA: Beautiful Chaos)

May

 * 15 - 18 - the Mandragora Helix attempts a takeover of Earth through the MorganTech computer systems (NSA: Beautiful Chaos).
 * The Earth is relocated to the Medusa Cascade by the Daleks under the control of the Supreme Dalek and Davros. Despite the relocation, the planet retains a full communications network. An invasion of Earth by the Daleks commences and a number of humans are taken to "the Crucible", the Dalek mothership, where they are killed in tests of the reality bomb. As part of a counter-insurgency against the Dalek invasion, former Prime Minister Harriet Jones brings together a number of the Doctor's former companions, including Captain Jack Harkness, Sarah Jane Smith, and Martha Jones in order to contact the Doctor, and before she herself is killed by the Daleks. Rose Tyler, meanwhile, contacts Donna Noble's family and is ultimately reunited with the Doctor. During this incident, The Doctor undergoes a partial regeneration in order to repair damage from a Dalek blast; as a result of this, the Doctor's severed hand later forms a mental link with Donna and grows into a second version of the Doctor, but one that's half-human without Time Lord biological abilities such as regeneration. During ths incident, Martha Jones, under orders from UNIT, reveals the existence of the Osterhagen Key, a weapon capable of destroying Earth. Due to her interaction with the second Doctor, Donna briefly gains the knowledge of a Time Lord, and with her help the two Doctors are able to defeat the Daleks. Afterwards, the Doctor and his companions are successful in restoring Earth to its original location using the TARDIS; this sparks worldwide celebrations around the planet. Afterwards, Mickey Smith chooses to remain on his original Earth instead of returning to Pete's World, Harkness offers Martha Jones a job with Torchwood Three, and the Doctor returns Rose and Jackie Tyler to Pete's World, along with his clone. Donna Noble is 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: The Stolen Earth/Journey's End) (Takes place within 6 weeks of NSA: Beautiful Chaos)
 * At some point during these events, a young girl named Adelaide Brooke loses her family and encounters a Dalek that, for reasons unknown to her, chooses not to exterminate her. This event inspires 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 further expand human reach into the stars. (DW: The Waters of Mars)
 * In the aftermath of the Medusa Cascade incident, the human race on Earth begins coming to terms with the fact it is not alone in the universe. While many accept it, others experience crises of faith and a large number of people commit suicide. (TW: Children of Earth: Day One)

June

 * Brian Green becomes British Prime Minister

September

 * Over the course of five days, every child on Earth periodically stops in their tracks and begin reciting the same message (permutations of "We are coming"). Officially, Earth's governments claim it to be caused by a form of virus. Behind the scenes, the truth is this is a message from the 456, a race that had visited Earth in 1965 and negotiated the payment of 12 orphan children in exchange for the cure for a pandemic-level influenza virus. The 456 return to Earth and demand the payment of a significant percentage of Earth's children (for use in creating a narcotic). As part of a cover-up to divert blame away from the UK government, which brokered the original deal, the Torchwood 3 hub in Cardiff is destroyed and attempts are made to assassinate Jack Harkness, Gwen Cooper and Ianto Jones. During the course of events, Thames House becomes the centre of 456-related negotiations, and at one point all occupants of the building are exposed to a deadly gas, killing all except for Mr. Dekker and Jack Harkness. Among those killed is Ianto Jones. Ultimately, through the efforts of Harkness - who was involved in the original 1965 deal - and the sacrifice of Harkness' grandson, the 456 are driven from Earth. (TW: Children of Earth Date based upon on-screen evidence, specifically a newspaper headline.)
 * During the course of these events, Gwen Cooper and husband Rhys Williams learn that she is pregnant.
 * The government of Prime Minister Brian Green is toppled soon after (assumption).
 * Stricken with guilt over the death of his grandson, Jack Harkness leaves Cardiff and spends the next few months wandering the Earth.

 * Toshiko Sato died by gunshot wound when she was shot by Gray, whilst Owen Harper expired after being expose to nuclear waste following the actions of Gray and John Hart. (TW: Exit Wounds)

Alternate timelines

 * The Year That Never Was: The Master rules the Earth with an iron fist. During this time, the Doctor, physically aged, is 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, spends the year travelling the world spreading stories and faith about the Doctor. Ultimately, the collected faith of the people of the world restore the Doctor which leads to the Master's defeat. Captain Jack destroys the Paradox machine, which reverses time back to 2008. Afterwards, the Master is shot by his wife, Lucy Saxon, and, refusing to regenerate, apparently dies (DW: Last of the Time Lords).
 * Donna's World - After the Titanic fell to Earth on 25th December 2008, annihilating London and rendering most of southern England unlivable with nuclear radiation, Great Britain has become a police state. Londoners lucky enough to have survived are subject to forced relocations; Donna Noble's family is moved to Leeds. Rose Tyler works with the UNIT of this timeline to help Donna Noble restore the proper chain of events which, at one point, involves sending Donna back to 2007. (DW: Turn Left)

Tennant jokingly introduces himself as Matt Smith at the read-through.
 * First issue of Doctor Who DVD Files, a fortnightly UK/Ireland-only magazine, is published, incorporating a DVD of the episodes DW: Rose and DW: The End of the World.
 * 16 - The website of the UK newspaper The Guardian publishes a column condemning then-rumored plans to film one of the 2009 specials in Dubai, citing the United Arab Emirates' human rights record.

These specials will mark the end of David Tennant's era as the Tenth Doctor, and also conclude Russell T Davies and Julie Gardner's tenures as producers. Concurrent with the start of production are rumours that Michelle Ryan and Lee Evans had been cast in the special. The rumours are later confirmed by the BBC, which releases publicity photographs of Ryan with David Tennant.

The resulting BBC News report serves as confirmation to earlier rumours that Doctor Who is in fact filming at least part of Planet of the Dead in the Middle Eastern country.

Following the 28 March deadline finalists will be chosen to take part in further competition on the series.

 * A trailer for the upcoming K9TV: K-9 spinoff series is unveiled at the MIPTV show in Cannes and is later posted online.
 * 3 - The BBC announces that outgoing Doctor Who executive producer Julie Gardner will be joining the Los Angeles branch of BBC Worldwide in June 2009, serving as executive producer of American-market projects.

This ends speculation over the future of Doctor Who on the CBC, although it's not yet known whether the CBC or related networks will retain broadcast rights to the first four seasons. Up to at least the end of Series 4, the CBC had been a (sometimes-credited) co-producer of the series; presumably this announcement means that arrangement has ended.
 * 09 - Audio adaptation of DWN: Doctor Who and the Masque of Mandragora is first released.
 * 11 - DW: Planet of the Dead is first broadcast, the first of four one-hour special episodes of Doctor Who scheduled for broadcast during 2009 and early 2010 in lieu of a regular season in 2009. Co-written by Russell T Davies and Gareth Roberts, it is the first episode on which Davies shares writing credit, is the first episode of the revived series to credit two writers, and is the first story to credit two writers since 1993's DW: Dimensions in Time. It is also the first episode (as opposed to telemovie) of the series to be filmed in part outside Europe since 1984. The BBC did not officially announce the broadcast date until 1 April, leading to some erroneous reports that it would air on Easter Sunday itself, 12 April. The special, the first to be filmed in high-definition, was simulcast on BBC HD.
 * An installment of Doctor Who Confidential follows on BBC Three.
 * 16 - NSA: Judgement of the Judoon, NSA: Prisoner of the Daleks and NSA: The Slitheen Excursion are first published.
