This page lists appearances of the Twelfth Doctor in the order in which he experienced them. This timeline is based upon observations of the Doctor Who universe and the events that occur during each of these stories. From these observations we have attempted to build a concise timeline. It is assumed that for each novel, comic, audio or television series, they're published, broadcast or numbered order is the order they occur in.

The layout of this timeline is in part based on the observations on Doctor Who - The Complete Adventures, as well as Lance Parkin's AHistory and other sources that allow us to make observations, such as Doctor Who Reviews, Clive Banks databanks, Whopix, and the Big Finish forums. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Timeline

Previous page: Eleventh Doctor

Early experiences

The Doctor regenerates from his previous incarnation.
Immediately after his regeneration, the Doctor decides to "take matters into [his] own hands" upon discovering that he still isn't ginger.
Follows directly on from The Time of the Doctor. After fending off Clockwork Droids with the Paternoster Gang in Victorian London, Clara sends the Doctor for coffee in 2010s Glasgow. As he settles into his new body, the Doctor refurbishes the TARDIS console room, such as changing the blue neon piping in the time rotor to amber, and begins to further ponder who gave Clara the TARDIS phone number.
During Deep Breath, after the Half-Face Man falls to his death, the Doctor stops to wonder if he remembered to cancel the milk before he left Gallifrey.
The Doctor helps in the saving of Gallifrey on the last day of the Last Great Time War, and, in the novelisation, travels to the War Room to coordinate disaster relief for Gallifrey. He is alone, has short hair, and his console room is glowing blue, suggesting this takes place after he left Clara, and before he redecorated the TARDIS, during Deep Breath.
The Doctor is getting coffee at the Intergalactic Coffee Roasting Station for Clara, setting this immediately after Deep Breath.
En route to deliver coffee to Clara, the Doctor saves Journey Blue from the Daleks, and is asked to venture into a broken Dalek to see if they can be redeemed. The Doctor picks up Clara from Coal Hill School, three weeks later from her perspective and after she meets Danny Pink, to help him, as he is unsure if he is still a "good man". After the Dalek sees hatred in him, the Doctor returns Clara to Coal Hill, both still unsure if he is "good", but convinced he is trying to be.
The Doctor is contemplating what he would be like as a Dalek, setting this immediately after Into the Dalek.

After travelling alone for a while, the Doctor learns that Danny was killed in a hit and run when Clara called him to explain everything to do with her travels. Deciding to help Clara find closure, the Doctor takes her to the 3W Institute and learns that the Master, now in a female body and calling herself "Missy", is preparing to invade London with the Cybermen, leading directly into Death in Heaven.
