Chronology
← Preceded by Followed by → "The Impossible Astronaut" "The Curse of the Black Spot"

"Day of the Moon" is the second episode of the sixth series of the British science fiction television series Doctor Who. Written by show runner Steven Moffat, and directed by Toby Haynes, the episode was first broadcast on 30 April 2011 on BBC One in the United Kingdom and on BBC America in the United States. The episode is the second of a two-part story that began with "The Impossible Astronaut".

In 1969 America, alien time traveller the Doctor (Matt Smith) attempts, alongside newlyweds Amy (Karen Gillan) and Rory (Arthur Darvill), companion River Song (Alex Kingston) and FBI agent Canton Everett Delaware III (Mark Sheppard), to lead the human race into a revolution against the Silence, a race of aliens who cannot be remembered after they are encountered.

"The Impossible Astronaut" and "Day of the Moon" were designed to be a darker opener to the series and were partially filmed in the United States, a first for the programme. Moffat was keen on incorporating Area 51, the moon landing, and President Richard Nixon (played by Stuart Milligan) into the plot. The episode received final viewing figures of 7.3 million in the UK. It received generally positive reviews from critics, though many worried about the number of questions that had been left unanswered.
