In Casino Royale, he is said to have bought a car in 1933 and to have been an experienced gambler before the Second World War. Two books later, in Moonraker, he is said to be in his middle thirties; the setting of this book can be no earlier than 1954 as it refers to the South Goodwin Lightship, which was lost in that year. There is a further reference to Bond’s age in You Only Live Twice, when Tanaka tells him he was born in the Year of the Rat (1924/25 or 1912/13).The books were written over a twelve-year period during which Bond’s age, when mentioned, thus varies, but is usually around forty.Other sources say Bond’s date of birth was November 16, 1924. As is also the case with the birthdays of Sherlock Holmes and his longtime biographer, Dr. John H. Watson, different people offer conflicting guesses on when to celebrate.

Really, though, whenever you choose to recognize Mr. Bond’s first appearance in the world is just fine with us.
