Early February
On 29 February, the Sixth Doctor and Charley Pollard arrived in Manchester and helped DI Patricia Menzies solve a murder. (AUDIO: The Condemned)
 * Jack Harkness and Toshiko Sato were transported back in time to The Ritz in 1941. Owen used the Rift Manipulator to bring them back, opening the Rift. By this point, Harold Saxon's campaign for election was underway as "Vote Saxon" signs were visible in Cardiff. (TV: Captain Jack Harkness)
 * As the Cardiff rift opened, the Rift quickly pulled beings through it at a steadier pace. Visions appeared to the Torchwood Three team and Rhys Williams was murdered. As a result, the Rift was closed, undoing the damage, but Abaddon was released, wiping out hundreds of people. Jack killed Abaddon with an overflow of life energy, which left Jack dead for days. (TV: End of Days) Shortly after being restored to life, Jack heard the sound of the Tenth Doctor's TARDIS and re-joined the Doctor as the TARDIS hurtled toward the year 100,000,000,000,000. (TV: End of Days, Utopia)
 * Meanwhile, Jack was declared missing by his Torchwood teammates, and Gwen Cooper took charge of the group. Subsequently, Ianto Jones began taking a more active role in field assignments. (TV: Kiss Kiss, Bang Bang)
 * The Eleventh Doctor met Amy Pond in Leadworth after twelve years of waiting. A Multi-form called Prisoner Zero, who had escaped through the crack in Amy's wall, attacked. The Atraxi arrived, threatening the destruction of Earth if Prisoner Zero did not surrender. The Doctor created a computer virus for the Atraxi to track back to its source in Leadworth (spread by Jeff). The Doctor also transmitted Prisoner Zero's disguises to the Atraxi so it couldn't hide in the bodies it had been disguised as. It then took the form of Amy; the Doctor made Amy think of Prisoner Zero's original form. Now in plain sight, Prisoner Zero was captured by the Atraxi, who left. The Doctor took a test drive of his refurbished TARDIS, only returning two years later. (TV: The Eleventh Hour)

Spring or Summer

 * Maria and Alan Jackson moved into 36 Bannerman Road, Ealing, the house opposite Sarah Jane Smith's. The Bane used a 'natural ingredient' hidden in their Bubble Shock! drink to enslave humanity. Sarah Jane and Maria went to the Bubble Shock! factory and stole their human archetype. The archetype used a communication device from a Star Poet to destroy the Bane Mother and freed the mind-controlled people. One Bane, Mrs Wormwood, escaped from the exploding factory. Sarah Jane adopted the Archetype and named him Luke. (TV: Invasion of the Bane)
 * The Slitheen family killed overweight teachers and created technology labs for their energy draining machine to cool the Sun, intending to sell the destroyed Earth. In the testing phases, the Earth briefly experienced a worldwide power outage. Luke unwittingly gave the code that would make the machine work properly to the Slitheen. Clyde Langer joined Luke, Maria and Sarah Jane in investigating the schools, fighting the Slitheen off with vinegar. When tried out on the Sun, the Slitheen's fixed machine overloaded and was destroyed in the confusion during its reset, killing two Slitheen while the others teleported to their ship. Sarah Jane used her supercomputer Mr Smith to orchestrate a cover-up that suggested the darkening of the sun and the power outage were caused by a sudden, but temporary, shift in Earth's magnetic field. (TV: Revenge of the Slitheen)
 * Royal Hope Hospital was teleported to the Moon with the Tenth Doctor and Martha Jones inside, for the Judoon to search for a murderer. Identified as non-human, the Doctor escaped the Judoon after he was mistaken for the murderer. The Doctor's blood was later sucked by Florence Finnegan (the murderer). Martha revived him. The Judoon positively identified and executed Finnegan. The Doctor stopped a supercharged MRI machine from wiping out Earth. The hospital was returned and Martha joined the Doctor in the TARDIS.

 * The Tenth Doctor, Jack and Martha returned from 100,000,000,000,000 and went on the run as fugitives declared by Harold Saxon, in fact the Master. The Master announced on television that humanity was to make first contact with the Toclafane. President Winters stepped in, allowing UNIT to take control. The Doctor, Martha and Jack snuck aboard the Valiant; the Toclafane murdered President Winters. The Master, seeing through the Doctor and his companions' perception filters, heavily aged the Doctor and captured him and Jack. (TV: The Sound of Drums)
 * The Year That Never Was began; the Master built a new "Time Lord Empire" and Martha Jones travelled the world executing the Doctor's plan. Ultimately, the year was negated and the clock reset to just after the Toclafane killed Winters. Lucy Saxon killed the Master. Martha Jones and Jack returned home and left the Doctor on his own. (TV: Last of the Time Lords) Lucy was subsequently imprisoned; unknown to her, a group of Saxon's followers retrieved his signet ring from his funeral pyre and began preparations for restoring the Master to life the following year. (TV: The End of Time, Part One)
 * Captain Jack returned to Torchwood Three and met John Hart, who was sent on a wild goose chase to find an Arcadian diamond.

Ianto Jones and Captain Jack Harkness exposed Adam after Ianto found no reference to him in his written diaries, and the team banished him to the Void by retconning themselves to forget the whole incident. (TV: Adam)
 * Sarah Jane Smith was given a puzzle box by a Verron soothsayer, with instructions to give it to someone she trusted. The next week she gave it to Maria Jackson.

Some of the passengers (including the waitress Astrid Peth) briefly landed in the middle of London. As the two previous Christmases had been disrupted by the arrival of alien spacecraft over London, (TV: The Christmas Invasion and TV: The Runaway Bride) most residents of the city had left for the season. Those choosing to remain in the city included Queen Elizabeth II and Wilfred Mott, grandfather of Donna Noble. A series of meteorites were deliberately allowed to collide with the deshielded Titanic, causing the ship and its nuclear storm drive to hurtle towards Earth. Most of the survivors of this collision were killed by the Heavenly Host. After the Doctor used the Host's security protocol to find the man in charge, Max Capricorn, Astrid followed, killing Capicorn but dying with him. The Doctor piloted the Titanic to safety, just missing Buckingham Palace. The only survivors were Midshipman Alonso Frame, Rickston Slade, the Doctor and Mr Copper.

As a result, the Earth was susceptible to the meteorite strike, fuelling chaos the Trickster could feed on. Maria was erased by Krislok.
