3 April

On 3 April 1938, in New York City, Rory Williams was sent back in time by the Weeping Angels from 2012. Later, baby Weeping Angels displaced him in space to Winter Quay, a "battery farm" for humans the Angels could send back in time. Seeing an older Rory die in one of Winter Quay's rooms that day, Rory and his wife, Amy, created a temporal paradox by jumping off Winter Quay's roof, undoing the older Rory's death and destroying the hotel. Amy, Rory, their son-in-law, the Eleventh Doctor, and their daughter, River Song, were returned to 2012. (TV: The Angels Take Manhattan)

Saturday 3 April 1926 was the date that the Third Doctor read on a copy of The Illustrated London News after they arrived on the SS Bernie. It was in fact on 4 June that they arrived, indicating the newspaper had been lying there for quite some time. (TV: Carnival of Monsters)
