Hola all!
This is just something I worked out for my own amusement: A timeline of events from the late 20th and early 21st Centuries in Doctor Who, as chronicled between the episodes "Rose" and "The Eleventh Hour."
I'm afraid it doesn't include much information from The Sarah Jane Adventures or Torchwood.
Some of it is speculative -- I just don't think that the Barack Obama seen in "The End of Time" could be the same individual who was the U.S. President in Children of Earth, as he was obviously a popular individual, and I don't buy for one second that anyone would celebrate an American President (or anyone else from his/her administration) who conspires to kidnap children and illegally take control of a major foreign ally's government. My theory is that the President and Vice President during Children of Earth -- like Prime Minister Green -- would have been forced to resign, and Obama would have then ascended to the Presidency from Congress after.
Also, while many characters referred to Arthur Coleman Winters from "The Sound of Drums" as U.S. President, or referred to his plane as Air Force One, Winters himself only called himself the President-elect. I don't buy that other characters would know his proper title and he wouldn't, and so I've chosen to base my timeline for Series Three on the assumption that Winters won the 2008 Presidential Election but had not taken yet taken office when Harold Saxon became Prime Minister, placing Series Three some time between 4 November 2008 and 20 January 2009. Since I try to assume that December is reserved for Christmas specials, I decided to place Series Three in mid-November, placing the 2008 U.K. General Election the second Thursday after the U.S. election.
While there is no evidence within the episode, promotional material for "The Eleventh Hour" has apparently indicated that the Doctor first met Amelia Pond in 1996; I base my timeline for Series Five on that assumption.
Another chronological assumption is that any episode set in the present takes place during the month that episode was first aired, unless there is evidence otherwise. Thus, for instance, I assume that the Battle of Canary Wharf took place in July because that's when the Series Two finale was first aired.
Anyway, here's my timeline!
1986: The Doctor and Rose attend the wedding of Pete and Jackie Tyler. (DW: "Father's Day")
