2012

Publicly, 2012 was the year that the Summer Olympics were held in London and a year that the United States held a presidential election. (TV: Dalek, Fear Her) Secretly, however, in an underground bunker in Utah, 2012 was the year that the Ninth Doctor first learned that he was not the only survivor of the Last Great Time War. (TV: Dalek)

According to one account, the United Kingdom had a king by this time. (PROSE: The Shadows of Avalon)

On 27 July, the 2012 Summer Olympics opened in London during a period of unseasonably cold weather in the city, caused by an Isolus pod draining all the nearby heat. The Tenth Doctor, his TARDIS and people inside the Olympic Stadium were all among those placed inside drawings made by Chloe Webber, aided by an Isolus to give the stranded Isolus a family. Digging up the pod, Rose Tyler threw it into the Olympic Flame to heat it up, resulting in the Isolus releasing those it had kidnapped. Due to an injured runner during the torch relay route, the Olympic Flame was lit at the opening ceremonies by the Doctor, who appeared on international television. The morale of the Games allowed the Isolus to fly home. Afterward, the Doctor and Rose attended a neighbourhood celebration in London. By this time, the Torchwood Institute seemed to have been relatively well-known, enough that the Battle of Canary Wharf of several years earlier was now known as the "Battle of Torchwood". (TV: Fear Her)

The Fifth Doctor attempted to take Nyssa and Tegan Jovanka to the 2012 Olympics but the TARDIS instead materialised in London in 1982. (AUDIO: The King of the Dead)

Somewhere around the same time, the Eleventh Doctor and Amy Pond met an athlete who was on the run from a Weeping Angel who was trying to steal the Olympic Flame in order to ruin the spirit of the Olympics, and ended up in the TARDIS. The Angel took the torch with the flame, but the Doctor destroyed the Angel with his screwdriver and received a gold medal for saving the Olympics. (TV: Good as Gold)

Rory was sent back in time by the Weeping Angels to New York City in 1938. After creating a paradox that destroyed the "battery farm" Winter Quay that year, he was sent back in time again from 2012 by a survivor of that event. Amy allowed the Angel to send her to Rory, and they "lived to death" together, forever separated from the Eleventh Doctor. (TV: The Angels Take Manhattan)

October - December
The United States held its presidential election. Earlier in the year, Diana Goddard suggested that the Democratic candidate would win, indicating that she found Democrats "funny". (TV: Dalek)

In Utah, in an underground facility called the Vault, the "last Dalek", nicknamed the Metaltron by its billionaire collector, Henry van Statten, used the DNA of the time traveller, Rose Tyler, to recover itself. Not having any orders from above, it killed most of the base, but hesistated once it approached Rose. Believing the humanity Rose had given it was "sickness", it allowed itself to be destroyed. Afterward, Adam Mitchell accepted an invitation to join the Ninth Doctor and Rose on their travels. Van Statten was stripped of his power and was ordered to have his memory erased. (TV: Dalek) At some point after this incident, the Vault was sealed and a BBC Radio documentary crew did an investigative report on the creatures known as Daleks. (AUDIO: The Dalek Conquests)
 * As the 2012 US election is referenced as having not happened yet, this means these events occurred prior to November.

The Ninth Doctor returned Adam Mitchell to his own time zone after expelling him from the TARDIS for sending information about future technology to his home era; Adam immediately caused a panic in his household when an advanced biochip implant from the year 200,000 was revealed in his forehead. (TV: The Long Game)
