In Act V, scene I of Shakespeare's" Hamlet", the First Gravedigger is asked by Hamlet at about line 147 and following, how long he has "been a grave-maker." His reply appears to determine the age of Hamlet in a roundabout but very explicit manner. The Gravedigger says that he has been in his profession since the day that Old Hamlet defeated Old Fortinbras, which was "the very day that young Hamlet was born." Then, a little later, he adds that "I have been sexton here, man and boy, thirty years." According to this logic, Hamlet must be thirty years old. Yorick, the dead jester whose skull Hamlet holds during this scene, is said to have been in the earth "three-and-twenty years," which would make Hamlet no more than seven years old when he last rode on Yorick's back.
