Larkin at Sixty (1982) is a collection of original essays and poems published to celebrate the sixtieth birthday of the English poet Philip Larkin. It was edited and introduced by Anthony Thwaite and published by Larkin's publishers, Faber and Faber. A poetic dramatisation of the launch of the book was written by Russell Davies.
Philip Larkin was born in January 1922.
We know he was born in 1922 because they were celebrating his 60th birthday in 1982, but it's never mentioned what month he was born in. It's difficult because the system was probably able to figure out that he must have been born in 1922 and ignored the month aspect of the question.
