Some of the dates listed below are provided quite differently in the novel; most, however, have been deduced by comparisons between events whose dates are known and events whose dates are not known. For example, the novel does not state when Jack Burden was born, but it does indicate that he was twenty-one in 1918; thus, he must have been born in 1897. In the following chronology, a question mark (?) beside a date indicates that no sure means of determining the exact date can be found in the novel.
