2010

April

 * 3 - The Number 200 bus travels from Earth to San Helios. The Doctor later saves everyone by getting them off the world. (DW: Planet of the Dead) There is no solid proof this happens a year after the events of Journey's End meaning that there is no proof this occurs in 2010. This could be the start of RTD moving the series back to the 'present' for Series 5.
 * 24 - Bernice Summerfield and Jason Kane are married at St. Christopher's Church, Cheldon Bonniface. (NA: Happy Endings)

Unknown dates

 * An alien race called the Samarands invade Greece (DWM: Hotel Historia).

Other timelines

 * Mickey Smith, Jake Simmonds and Pete travel from a parallel world back to the Doctor's universe. They and Rose and Jackie Tyler are stuck in Pete's World after the tear through the Void closes.
 * Due to time differences between the two worlds, they appear in 2007 in the other world. See also Pete's World.

Real World

 * The 5th series of Doctor Who is scheduled for broadcast this year, consisting of 13 episodes with Steven Moffat taking over from Russell T Davies as executive producer, and Matt Smith taking over the role of the Doctor from David Tennant. Production of the season is expected to begin in 2009, and is expected to carry over into 2010 per the precedent of previous seasons.
 * Assuming it is renewed, production of Series 6 of Doctor Who will presumably begin in the second half of 2010, for broadcast in 2011. As of January 2009 it has not yet been announced as to whether this will include another Christmas special, which would air around December 25, 2010.
 * It is likely that, barring any decision to release the specials earlier, that the 2009 specials will receive DVD release in a box set in early 2010, after the broadcast of David Tennant's final special.
 * Broadcast of the first season of the spin-off series K-9 is expected to continue into 2010 in its country of production, Australia. Broadcast plans for elsewhere in the world have yet to be announced.

"Early 2010"

 * According to media reports in October 2008, the final "gap year" special episode of Doctor Who may not be broadcast until early 2010, contradicting earlier reports that they would all air in 2009. This final special, whenever it airs, will be the last under the watch of producers Russell T. Davies and Julie Gardner and the last to feature David Tennant as the Tenth Doctor; it is not yet known whether the actor chosen to play the Eleventh Doctor, Matt Smith will appear in the special as well.
 * In March 2009 it was learned via a Russell T. Davies interview in SFX Magazine that the final three specials of the gap year would air around "Christmas/late 2009". As the exact airdates have yet to be announced as of March 2009, a New Year's Day broadcast is possible for one of the specials.

March

 * 26 - Fifth anniversary of the return of Doctor Who to television.

December

 * According to an announcement made by IDW Publishing at the New York Comic Con in February 2009, the comic book series Doctor Who Ongoing is scheduled to begin publishing original adventures featuring the Eleventh Doctor as of its 18th issue, scheduled for publication this month.
