22 April

5:02 PM on 22 April, 2011, at Lake Silencio, Utah, was a still point in time, which made it easier for the Silence to create a fixed point in time.

On that day, River Song, in a space suit emerged from the lake and supposedly killed the 1103-year-old Eleventh Doctor, before he was able to regenerate. In reality, the Doctor was in a Tesselecta during the murder, and remained unharmed during the whole process. (TV: The Impossible Astronaut, The Wedding of River Song)

The Eleventh Doctor, at age 1103, recruited via numbered envelopes a 909 year old version of himself (1), an older River Song (2), Amy Pond and Rory Williams (3), and Canton Delaware (4). All arrived in Utah and, except the younger Doctor, met up with the older Doctor. After his supposed death, they cremated his death on a boat and let it float away.

After cremating the Teselecta, River, Amy and Rory went to a diner where they encountered his younger self. They left in the Doctor's TARDIS to the Oval Office in 1969. (TV: The Impossible Astronaut)

An alternate timeline was created when River instead exhausted the weaponry of the astronaut suit, and didn't "kill" the Doctor. Immediately, a new reality came into being where all of history happened at once, and the time remained 5:02 PM on 22 April, 2011 forever. In this reality, the Eleventh Doctor and River Song got married. The timeline was reverted when the Doctor and River, the opposite poles of the disruption, kissed, the proximity shorting out the differential, and letting time continue its course.
